›FIELD OF THE INVENTION

The present invention relates to novel arylsulphonamides having affinity to dopaminergic, serotoninergic, adrenergic, sigma and serotonine transporter receptors, pharmaceutical compositions containing the same and to the use thereof. The compounds may be useful for the treatment of diseases of the central nervous system, such as schizophrenia, bipolar affective disorder, depression, anxiety disorders, sleep disorders or Alzheimer disease.

›STATE OF THE ART · 1 of 4

CNS disorders are considered a global medical problem. A number of people suffering from those diseases constantly grows, particularly in highly developed countries and intensively developing ones. Approximately 20% of population in highly developed societies suffers from CNS disorders. In addition a cost of treatment of such disorders represents nearly 35% of total expenses spent for treatment of all medical diseases in seven countries considered as the biggest pharmaceutical markets.

Among all psychiatric diseases, schizophrenia, bipolar disorder, depression, anxiety, sleep disorders and addictions are the major ones. The main neurologic disorders are Alzheimer's disease, Parkinson's disease, epilepsy and different pain disorders.

Antipsychotic drugs, which are main treatment of schizophrenia, are divided into two main classes on the basis of their liability to induce neurological side effects after long-term treatment. Typical antipsychotic drugs, such as chlorpromazine and haloperidol, induce after repeated administration various extrapyramidal side effects (EPS) including Parkinson-like symptoms and tardive dyskinesia. Repeated treatment with so called atypical antipsychotic drugs, such as clozapine, risperidone, olanzapine, quetiapine, ziprasidone and aripiprazole, is associated with a lower incidence of neurological side effects. Typical antipsychotics reduce positive symptoms but do not reduce negative symptoms and cognitive dysfunctions. Plasma prolactin levels are increased in humans, and there is a gain in bodyweight potentially leading to the development of metabolic syndrome. Atypical antipsychotic drugs effectively reduce positive symptoms and also to some extent negative symptoms and cognitive disturbances producing less serious EPS. Atypical antipsychotic drugs differ in their propensity to elevate plasma prolactin levels in humans. Typical antipsychotic drugs block dopamine D2 receptors in the mesolimbic and nigrostriatal system. This mechanism is responsible for the antipsychotic effect (reduction of positive symptoms) as well as induction of EPS. Clinical support for the dopamine hypothesis of antipsychotic drug action was provided by PET findings of high dopamine D2 receptor occupancy in the striatum of patients responding to different antipsychotic drug treatments. Patients with a good response show dopamine D2 receptor occupancy of more than 65% (Nord and Farde 2010). The occurrence of EPS seems to be related to a higher occupancy of dopamine D2 receptors (above 80%). Atypical antipsychotics, also called second generation antipsychotic drugs, have clinical approvals for the treatment of psychosis and mania. Each drug has a unique pharmacodynamic and pharmacokinetic profile. Some of atypical antipsychotic drugs have additional antidepressant, anxiolytic or hypnotic profile (Schwartz and Stahl 2011). Atypical antipsychotic drugs have in common a potent serotonin 5-HT2A receptor antagonism in relation to a weaker dopamine D2 receptor antagonism. This pharmacodynamic property is the basis of “atypicality” (Meltzer 1989). Antagonism of 5-HT2A receptors likely allows more dopamine activity and neurotransmission to occur in the nigrostriatal system to avoid EPS. The same mechanism may allow small improvement in negative symptoms, and 5-HT2 antagonism in the tuberoinfundibular pathway may help to avoid hyperprolactinemia (Schwartz and Stahl 2011).

The atypical antipsychotics have not fulfilled the initial expectations of improved negative symptoms and cognitive dysfunctions in schizophrenia. Therefore, more molecular targets are presently under investigation for the development of new drugs for the treatment of schizophrenia (Gray and Roth 2007; Schizophrenia Research Forum 2007).

Dopaminergic D3 receptors are localized in limbic cortex and thus a preferential blockade of these receptors offers locally selective antidopaminergic activity. This results in increased effectiveness in reducing positive symptoms of schizophrenia sparing the blockade of extrapyramidal system and therefore reduces the risk of the main side effect such as pseudoparkinson's syndrome. Moreover, several preclinical data suggests that D3 dopamine receptor antagonism is more efficient in reducing the negative symptoms of schizophrenia and improves working memory.

Agonism or partial agonism of 5-HT1A receptors is considered a possible mechanism associated with the activity of some atypical antipsychotics such as aripiprazole and ziprasidone. It is assumed that stimulation of 5-HT1A receptors takes part in the antipsychotic effect in combination with D2 receptor blockade, especially in the safety profile of drug as well as is beneficial in fighting mood and cognitive symptoms of schizophrenia (Kim D., Building a Better Antipsychotic: Receptor Targets for the Treatment of Multiple Symptom Dimensions of Schizophrenia, Neurotherapeutics, 6(1), 78-85, 2009).

Serotoninergic receptors type 5-HT6 are exclusively localized in the central nervous system (CNS). Both the localization of the 5-HT6 receptors in limbic and cortical brain areas and relatively potent affinity and antagonistic activity of several antipsychotics (clozapine, olanzapine, sertindole) and antidepressants (mianserin, amitryptiline) at 5-HT6 receptors are suggestive of a potential role in pathophysiology and treatment of CNS disorders. Recent data in the literature indicate that blockade of 5-HT6 receptors may be implicated in a pro-cognitive effect due to the increase in cholinergic transmission, in antidepressant activity due to the increase in noradrenergic and dopaminergic one, as well as in an anxiolytic effect. It is evident that the 5-HT6 receptor has emerged as a very interesting molecular target and antagonists of that receptor may serve as potential drugs in treatment of disorders characterized by cognitive impairments, such as Alzheimer's disease, schizophrenia, depression, anxiety is (Liu K. i Robichaud A., 5-HT6 Antagonists as Potential Treatment for Cognitive Dysfunction, 2009; Wesotowska A. i Nikiforuk A., Effects of the brain-penetrant and selective 5-HT6 receptor antagonist SB-399885 in animal models of anxiety and depression, 2007). Moreover, 5-HT6 receptor antagonists have been demonstrated to be active in reduction of food intake and body weight by clinically approved mechanism that is consistent with an enhancement of satiety. Hence, several compounds with 5-HT6 receptor antagonistic activity are currently being clinically evaluated for the treatment of obesity (Heal D. et al., Selective 5-HT6 receptor ligands: progress in the development of a novel pharmacological approach to the treatment of obesity and related metabolic disorders, 2008).

›STATE OF THE ART · 2 of 4

Intensive research conducted since 1993 indicates that serotoninergic 5-HT7 receptors may play some role in the control of circadian rhythms, sleep, thermoregulation, cognitive processes, pain and migraine, as well as in neuronal excitability. Potent affinity and antagonistic activity of several antipsychotic and antidepressant drugs at 5-HT7 receptors suggest a potential role of these receptors in the pathophysiology of many neuropsychiatric disorders. Taking account of the behavioral data presented in the literature, it has been established that selective 5-HT7 receptor antagonists produce antidepressant and anxiolytic activity in rats and mice (Wesotowska A. et al., Effect of the selective 5-HT7 receptor antagonist SB-269970 in animal models of anxiety and depression, 2006). Using mouse models of antipsychotic activity, Galici et al. showed that a selective 5-HT7 receptor antagonist SB-269970 may also evoke antipsychotic-like effects (Galici R. et al., Effects of SB-269970, a 5-HT7 receptor antagonist, in mouse models predictive of antipsychotic-like activity, 2008).

Serotoninergic 5-HT2C and histaminergic H1 receptors localized in hypothalamus play an important role in food intake regulation. Blockade of both types of these receptors produced by antipsychotic drugs is most closely correlated with an increased risk of weight gain and diabetes. On the other hand, blockade of 5-HT2C receptors, mostly localized in cortical areas and in the hippocampus, striatum, septal nuclei, thalamic and midbrain nuclei, may produce profitable antidepressant and pro-cognitive effects. In the substantia nigra, 5-HT2C receptors are co-localised with GABA, indicating that they so yield indirect control of dopaminergic transmission. Consequently, the blockade of 5-HT2C receptors, together with the 5-HT2A receptor one, would potentiate the D2 receptor-mediated tonic inhibitory control of dopaminergic projection, with protective effect against extrapyramidal symptoms (Kim D., Building a Better Antipsychotic: Receptor Targets for the Treatment of Multiple Symptom Dimensions of Schizophrenia, 2009). Histaminergic H1 receptor blockade produced by antipsychotic drugs may be implicated in sedative effect that is clinically profitable in controlling arousal accompanies the acute phase of psychosis. It seems that simultaneous reduction in affinity of new molecule for both types of these receptors may be an element that protects against excessive body weight. However, the total elimination of affinity for these receptors may not be necessary because of certain benefits of blockade of 5-HT2C and H1 receptors.

Blockade of alpha1 adrenergic receptors, despite potential peripheral adverse effects involving hypotension, may cause some central nervous system benefits involving decrease in the risk of extrapyramidal side effects caused be antipsychotics. This may be associated with interaction between noradrenergic and serotoninergic neurons (Horacek J. et al., Mechanism of Action of Atypical Antipsychotic Drugs and the Neurobiology of Schizophrenia, CNS Drugs, 20(5), 389-409, 2006).

Blockade of alpha2 adrenergic receptors potentiates antidepressants-induced increase of extracellular monoamines. This may suggest that substances inhibiting monoamine transporters and simultaneously blocking alpha2 adrenergic receptors may be potent and fast acting new antidepressants. Moreover, alpha2 antagonists potentiate acetylcholine secretion in the frontal cortex and may improve cognitive functions, what may provide additional advantages both in antidepressant therapy and antipsychotic therapy (especially improvement in negative symptoms). Blockade of alpha2 adrenergic receptors may also counteract sexual dysfunctions caused by serotonin reuptake inhibitors (Millan M., Dual- and Triple-Acting Agents for Treating Core and Co-morbid Symptoms of Major Depression: Novel Concepts, New Drugs, 2009). Alpha2 antagonists may also be beneficial in reducing extrapyramidal symptoms caused by blockade of D2 receptors in the striatum.

Sigma receptors are a separate group of CNS receptors; however their physiological role is still unknown. It has been shown that some psychotomimetic substances like phencyclidine, metamphetamine, heroin or dextrometorphan are potent sigma receptor agonist. On the other hand, a classic antipsychotic drug, haloperidol, is a strong antagonist of sigma receptors, what may be important for its antipsychotic potential. It has been established that selective sigma receptor agonists may produce antidepressant effect (Cobos E. et al., Pharmacology and Therapeutic Potential of Sigma Receptor Ligands, 2008). The above findings provide evidence that sigma receptors affinity may contribute to the overall beneficial pharmacological profile of a new psychotropic drug.

Because of important role of cholinergic system in the cognitive processes, current research is focused on substances which can directly or indirectly potentiate the activity of cholinergic system. This includes substances which are agonists of selected subtypes of nicotinic or muscarinic receptors and antagonists of 5-HT6 receptors. On the other hand, potential procognitive effects evoked by interaction with the above receptors may be masked by cholinolytic activity. Thus, in the scope of interest are substances free of antagonistic properties against cholinergic receptors. Moreover this strategy allows elimination of many undesired peripheral autonomic effects like constipations, dry mouth or tachycardia (Miamoto S., Treatments for schizophrenia: a critical review of pharmacology and mechanisms of action of antipsychotic drugs, 2005). In addition, it has been found that M3 muscarinic receptors are engaged in the control of insulin secretion, and their activation stimulates pancreas to secrete insulin. Hence, it can be expected that M3 receptors blockade may be unfavorable in terms of the risk of development of type II diabetes in patients treated with second generation antipsychotics (ex. olanzapine, clozapine, quetiapine). Recent research is focused on substances free of this undesired effect (Silvestre J. i Prous J., Research on adverse drug events. I. Muscarinic M3 receptor binding affinity could predict the risk of antipsychotics to induce type 2 diabetes, 2005).

›STATE OF THE ART · 3 of 4

Another serious side effects caused by antipsychotic drugs, e.g. sertindole, ziprasidone, are cardiac arrhythmias associated with delayed repolarization of cardiomyocytes. This condition appears on electrocardiograms (ECG) as prolonged corrected QT interval (QTc), what is most often evoked by substances which block hERG potassium channels. To prevent introduction to the developmental pipelines drugs with pro-arrhythmic potential, at a very early stage of research new substances are screened in vitro for their potency to block hERG potassium channels, using electrophysiological methods (Recanatni M., QT Prolongation Through hERG K+ Channel Blockade: Current Knowledge and Strategies for the Early Prediction During Drug Development, 2005).

Despite the advances that have been made in the development of antidepressants, there are clearly still unmet clinical needs with respect to both efficacy and side effects. These needs range from efficacy in treatment resistant patients (about 30%) to improved onset, to reductions in side effects such as sexual dysfunction, gastrointestinal events, sedation, weight gain. There are multiple approaches to improve current pharmacological means of modulating biogenic amines neurotransmission by either combining mechanisms or alternatively selectively stimulating/blocking receptor subtypes that may trigger improved efficacy or fewer side effects. One of them is combination therapies that maintain the benefits associated with selective serotonin reuptake inhibitors (SSRIs) (blockers of serotonin transporter) but attempt to either improve efficacy or reduce side effects by adding additional mechanism involving blockade of 5-HT2A or 5-HT2C receptors (Millan M., Dual- and Triple-Acting Agents for Treating Core and Co-morbid Symptoms of Major Depression: Novel Concepts, New Drugs, Neurotherapeutics, 6(1), 53-77, 2009). 5-HT2A receptor antagonists administered alone may produce antidepressant activity and also co-administered with SSRIs augment their antidepressant effects. The mechanism for this interaction may be a further increase in extracellular serotonin levels produced when SSRIs are given with 5-HT2A antagonists. Moreover, blockade of 5-HT2A receptors is part of the pharmacological profile of antidepressant drugs such as mianserin and mirtazapine. Presynaptic 5-HT1A receptors are associated with the risk for depressive behavior and their blockade augments the effects of SSRIs. Postsynaptic 5-HT1A receptors are essential for producing the antidepressant effects of 5-HT1A receptor agonists and possibly SSRIs. Thus partial agonism of 5-HT1A receptors is a preferred feature for new molecules the more that this mechanism occurs in approved anxiolytic buspirone and antidepressant/anxiolytic tandospirone.

Although introduction of new psychotropic drugs (among others narcoleptics, antidepressants, benzodiazepines, acetylocholinesterase inhibitors) since 50-thies of the XX century was an unquestioned breakthrough, therapy of neuropsychiatric disorders is still far from satisfactory both because of limited efficacy and wide spectrum of side effects evoked by available drugs. These disadvantages are a challenge for modern pharmacotherapy and there is a continuous effort to search for new, more effective psychotropic drugs.

b) General Procedure for Compounds Wherein in Formula (IIa) Represents Double Bond.

0.2 Mmol of amine (IIa) was dissolved in 5 ml of anhydrous N,N-dimethylformamide, and then 4 mmol of N,N-diisopropylethylamine was added. The mixture was purged with argon, and 0.24 mmol of appropriate arylsulphonyl chloride was subsequently added (IIb). After 30 minutes of stirring at room temperature the mixture was poured into is about 20 ml of ice water. The mixture was extracted with ethyl acetate or methylene chloride. Organic layer was washed with brine, dried over anhydrous sodium sulphate, and then concentrated under reduced pressure. Crude sulphonamides were usually purified by means of crystallization (from methanol), and some of them using column chromatography on silica gel with using methylene chloride/methanol 20:1 as eluent. Structure of prepared compounds was confirmed by MS data, and purity by HPLC analysis. For selected compounds structure identification was further confirmed by 1 H-NMR analysis.

Following the general procedure described above and starting from appropriate compounds amine (IIa) and arylsulphonyl chloride (IIb), the following compounds were obtained.

›EXAMPLE 6

Ability to block hERG potassium channels was determined using the electrophysiological method and cloned hERG potassium channels (KCNH2 gene, expressed in CHO cells) as biological material. The effects were evaluated using IonWorks™ Quattro system (MDS-AT).

hERG Test Procedures

hERG current was elicited using a pulse pattern with fixed amplitudes (conditioning prepulse: −80 mV for 25 ms; test pulse: +40 mV for 80 ms) from a holding potential of 0 mV. hERG current was measured as a difference between the peak current at 1 ms after the test step to +40 mV and the steady-state current at the end of the step to +40 mV.

Data Analysis

Data acquisition and analyses was performed using the IonWorks Quattro™ system operation software (version 2.0.2; Molecular Devices Corporation, Union City, Calif.). Data were corrected for leak current.

The hERG block was calculated as: % Block=(1−I TA/(Control)×100%, where IControl and ITA were the currents elicited by the test pulse in control and in the presence of a test compound, respectively. Results are presented in Table 24.

›EXAMPLE 7

Guinea-Pig Ileum Test

Ileum was prepared from male guinea-pigs with 300-350 g of body weight, fasted for 24 h before experiment with free access to drinking water. Terminal ileum was dissected and placed into a Krebs solution (NaCl 120 mM, KCl 5.6 mM, MgCl 2 2.2 mM, CaCl 2 2.4 mM, NaHCO 3 19 mM, glucose 10 mM) and 2 cm-long fragments were cut. Each segment of the gut was placed in 30 ml chamber filled with the Krebs solution at 37 C, pH 7.4, with constant oxygenation (O 2 /CO 2 , 19:1), fixed by the lower end to a glass rod and by the upper end to the force-displacement transducer FDT 10-A (Biopac Systems, COMMAT, Ltd., Turkey). The preparation was allowed to stabilize in organ baths for 60 min under a resting tension of 0.5 g, washing every 15 min with fresh Krebs solution. All responses were recorded using software Biopac Systems Inc MP-35 Data Acquisition, Turkey.

Stock solutions of test and reference compounds were prepared in concentration 10 −3 M. About 1 mg of each tested compound was weighed and dissolved in appropriate volume of dimethyl sulfoxide, ethanol or water or in a mixture of them (depending on the solubility). In next step, stock solutions were diluted 10× in water.

The equilibration period a cumulative concentration-response curve was constructed in so each tissue for respective agonist—carbachol (3×10 −9 −3×10 −6 M) or histamine (10 −8 -10 −5 M) by the method of van Rossum (Ref. 24). Following the first agonist curve, tissues were incubated with one of the concentrations of tested compounds for 15 min and the next cumulative concentration curve to agonist was obtained. Only one concentration of the antagonist was tested in each piece of tissue. Experiments were repeated three to eight times.

After the equilibration period a cumulative concentration-response curve was constructed in each tissue for histamine (10 −8 -10 −5 M) by the method of van Rossum. Following the first histamine curve, tissues were incubated with one of the concentrations of tested compounds for 15 min and the next cumulative concentration curve to histamine was obtained. Only one concentration of the antagonist was tested in each piece of tissue. Experiments were repeated three to seven times.

Concentration-response curves were analysed using GraphPad Prism 4.0 (GraphPad Software Inc., San Diego, Calif., USA). Contractile responses to carbachol (in the presence or absence of tested compounds) are expressed as a percentage of maximal carbachol effect (Emax=100%), reached in the concentration-response curves obtained before incubation with the tested compounds. The data are expressed as the mean±SEM of at least four separate experiments. The affinity was estimated with the equation pKB=log(concentration ratio−1)−log(molar antagonist concentration), where the concentration ratio is the ratio of equieffective agonist concentrations in the absence and in the presence of the antagonist.

Results of in vitro tests as described in Examples 4-7 show that compounds of the invention display high affinity for dopamine and serotonin receptors, especially D2, D3, 5-HT1A, 5-HT2A, 5-HT6 and 5-HT7 subtypes, adrenergic alpha2C and alpha1A as well as sigma receptors and serotonin transporter. Most of the tested compounds possess antagonistic profile for all of the receptors they have affinity for, with some of them showing partially agonistic properties for D2 and/or D3 receptors as well as fully or partially agonistic activity towards 5-HT1A receptors. This confirms their potential usefulness in the treatment of diseases connected with disturbances in dopaminergic, serotoninergic and noradrenergic transmission, e.g. psychoses, depression as well as anxiety disorders etc. It should be stressed that some of the compounds possess parallel (simultaneous) affinity for D2, 5-HT6 and 5-HT7 receptors, displaying efficient antagonistic properties for all of them, which particularly differentiates them from the compounds currently used for treatment of abovementioned diseases. Such a pharmacological profile suggests possible efficacy in the treatment of psychoses as well as precognitive and antidepressant activity. In the same time compounds of the invention possess weak affinity for potassium hERG channel and muscarine receptors as well as moderate affinity for H1 and 5-HT2C receptors, what may potentially contribute to reduced side effects such as, arrhythmia, vegetative disorders, weight gain and metabolic disorders, which are frequently caused by many of the currently used drugs for treatment of the abovementioned diseases.

Male CD-1 mice weighing 20-22 g derived from accredited animal facility localized at Medical College of Jagiellonian University, male C57BL/6J mice weighing 20-21 g and male Swiss Albino mice weighing 21-22 g derived from the licensed dealer (Staniszewska; Ilkowice, Poland) were group-housed for 3-4 day period in polycarbonate Makrolon type 3 cages (dimensions 26.5×15×42 cm) in an environmentally controlled, experimental room (ambient temperature 22-20 C; relative humidity 50-60%; 12:12 light:dark cycle, lights on at 8:00), in groups of 15. Male Wistar rats weighing 205-225 g upon arrival from accredited animal facility Charles River (Sulzfeld, Germany) were group-housed for 6 day period in polycarbonate Makrolon type 3 cages (dimensions 26.5×15×42 cm) in an environmentally controlled room (ambient temperature 20-22′C; relative humidity 50-60%; 12:12 light:dark cycle, lights on at 8:00), in groups of 4. Standard laboratory food (LSM-B) and filtered water were freely available. Standard laboratory food (Ssniff M-Z) and filtered water were freely available. On the day before experiments the equipment produces “white noise” was turned on for 30 minutes and mice or rats were weighted exact to 1 g. Animals were assigned randomly to treatment groups. All the experiments were performed by two observers unaware of the treatment applied between 9:00 and 14:00 on separate groups of animals. All animals were used only once and were killed immediately after the experiment. All the experimental procedures were approved by the IV Local Bioethics Commission in Warszawa.

d-Amphetamine-Induced Locomotor Hyperactivity

The locomotor activity was recorded with an Opto M3 multi-channel activity monitor (MultiDevice Software v. 1.3, Columbus Instruments). The mice were individually placed in plastic cages (22×12×13 cm) for 30 minutes habituation period, and then the crossings of each channel (ambulation) were counted during 1 h with data recording every 5 minutes. The cages were cleaned up with 70% ethanol after each mouse. Drugs were administered to 10 mice per treatment group. d-Amphetamine was administered 30 minutes before the test. Compound 22 was given 30 minutes before the experiment, and other compounds were given 60 minutes before the experiment.

MK-801-Induced Locomotor Hyperactivity

The locomotor activity was recorded according to method described above. Instead of d-Amphetamine, MK-801 was administered 15 min before the test. Compound 22 was given 30 minutes before the experiment.

Tail Suspension Test in C57BL/6J Mice

The testing procedure was based on a method of Steru et al. (The tail suspension test: a new method for screening antidepressants in mice, Psychopharmacology 85, 367-370, 1985). An automated device (Kinder Scientific) was used. Mice were suspended by the tail with tape to an aluminum hook connected to a strain gauge. Mice were positioned such that the base of their tail was aligned with the bottom of the hook. This positioning was found to decrease the propensity for mice to climb their tail during the test. A strain gauge connected to computer software detected any movements by the mouse in order to record the number of times (events) each subject enters into an escape behavior (struggling episodes), the duration of the event, and the average strength of each event during a 6-min test session. The total duration of immobility was calculated as the time the force of the mouse's movements was below a preset threshold. An optimum threshold was determined by comparing manually scored videotapes with automated scores. The following settings were used in all experiments: threshold 0, 20 Newtons, off delay 30 msec. Drugs were administered to 7-8 mice per treatment group. Compound 22 was given 30 minutes, while Compound 36 was given 60 minutes before the experiment.

Four-Plate Test in Swiss Mice

The four-plate test (BIOSEB, France) was performed in a cage (25×18×16 cm) floored by four identical rectangular metal plates (8×11 cm) separated from one another by a gap of 4 mm. The top of the cage was covered by a transparent Perspex lid that prevented escape behaviour. The plates were connected to a device that can generated electric shocks. Following a 15-s habituation period, the animal's motivation to explore a novel environment was suppressed by an electric foot shock (0.8 mA, 0.5 s) every time it moved from one plate to another during a 1-minute test session (Aron et al., Evaluation of a rapid technique for detecting minor tranquilizers, Neuropharmacology 10, 459-469, 1971). This action is referred to as a ‘punished crossing’, and was followed by a 3 s shock interval, during which the animal could move across plates without receiving a shock. Drugs were administered to 8-10 mice per treatment group. Compound 22 was given 30 minutes, while Compound 36 was given 60 minutes before the experiment.

›EXAMPLE 9 · 1 of 3

Activity Testing in Rats

Drug-naive male Wistar rats (Charles River, Sulzfeld, Germany) weighing 250-400 g were used in all experiments. Rats were housed two per standard plastic cage and kept in a room with constant environmental conditions (21-22′C, relative humidity 60%, a 12:12 light-dark cycle with lights on at 7:00 a.m.). Animals were supplied by the breeder two weeks before the onset of behavioral procedures. During this time, the subjects were weighed and handled several times. Tap water and standard lab chow (Labofeed H, WPIK, Kcynia, Poland) was available ad libitum.

Test Compounds

Compounds 22 and 36 were prepared as a suspension in 1% aqueous solution of Tween 80, whereas d-amphetamine and MK-801 were dissolved in distilled water immediately before administration. An injection volume of 10 ml/kg (mice) or 2 ml/kg (rats) was used throughout and all compounds were administered intraperitoneally (i.p.), except d-amphetamine that was given subcutaneously (s.c.).

Statistical Analysis

All the data are expressed as the mean±SEM. The statistical significance of effects was evaluated using separate one-way analysis of variance (ANOVA) with comparison between individual groups by Dunnett's test (when only one drug was given) or by the Tukey's test when two drugs were used; p<0.05, p<0.01 and p<0.001 were considered statistically significant. ED 50 values were calculated using Graph Pad Prism 5 Software.

Apomorphine-Induced Stereotyped Behaviour

All tests were carried out in a sound-attenuated experimental room between 9:00 a.m. and 3:00 p.m. Within 24 h prior to testing, rats were habituated to glass observation so cages (25×25×40 cm, W×H×L) with wood chip bedding on the floor for 20 min. On the day of testing, stereotyped behaviour was observed 20 to 25 min. after apomorphine injection (s.c.) as described by Bristow et al. (L-745,870, a subtype selective dopamine D4 receptor antagonist, does not exhibit a neuroleptic-like profile in rodent behavioral tests. J Pharmacol Exp Ther, 1997; 283:1256-63) and Feldman et al. (Mixed D2/5-HT2 antagonism differentially affects apomorphine- and amphetamine-induced stereotyped behavior. Pharmacol Biochem Behav. 1997; 58:565-72). Rats were injected with apomorphine (0.6 mg/kg) and placed in the observation cages. Views of other rats in the experiment were prohibited. Twenty minutes later, the time spent licking/biting and sniffing downward was recorded by a trained observer for 5 minutes (300 s). Rats were pre-injected i.p. with a test drug 60 min. before the start of the 5-min. test session (the observation period).

The duration of stereotyped sniffing and licking/biting was analyzed with the aid of the Kruskal-Wallis analysis of variance (ANOVA). The Mann-Whitney U test was used for individual post hoc comparisons. P values lower than 0.05 were considered significant.

MK-801-Induced Stereotyped Behaviour

All tests were carried out in a sound-attenuated experimental room between 9:00 a.m. and 3:00 p.m. Within 24 h prior to testing, rats were habituated to glass observation cages (25×25×40 cm, W×H×L) with wood chip bedding on the floor for 20 min. On the day of testing, stereotyped behaviour was observed 15 min. after MK-801 so administration. Rats were injected with MK-801 (0.6 mg/kg, i.p.) and placed in the observation cages. Views of other rats in the experiment were prohibited. Fifteen minutes later, the time spent circling/head waving was recorded by a trained observer for 5 min. (300 s). Rats were pre-injected with a test drug 60 min. before the start of the observation period.

The duration of stereotyped circling was analyzed with the aid of the Kruskal-Wallis analysis of variance (ANOVA). The Mann-Whitney U test was used for individual post hoc comparisons. P values lower than 0.05 were considered significant.

2,5-Dimethoxy-4-Iodoamphetamine (DOI)-Induced Head Twitches

All tests were carried out in a sound-attenuated experimental room between 9:00 a.m. and 3:00 p.m. as described above for spontaneous head twitches. DOI-induced head twitches were scored as described by Millan et al. (518327 (1-[2-[4-(6-fluoro-1,2-benzisoxazol-3-yl)piperid-1-yl]ethyl]3-phenyl imidazolin-2-one), a novel, potential antipsychotic displaying marked antagonist properties at alpha(1)- and alpha(2)-adrenergic receptors: II. Functional profile and a multiparametric comparison with haloperidol, clozapine, and 11 other antipsychotic agents. J Pharmacol Exp Ther 2000; 292:54-66). Rats were pre-injected i.p. with a test drug 60 min. before the start of the test session. Fifty five minutes later, rats were injected with DOI (2.5 mg/kg, i.p.) and placed in glass observation cages (25×25×40 cm, W×H×L) with wood chip bedding on is the floor. Five minutes later, head twitches were counted for 5 minutes. (300 s) by a trained observer.

Total numbers of head twitches (n/5 min.) were analyzed by means of the Kruskal-Wallis analysis of variance (ANOVA). The Mann-Whitney U test was used for individual post hoc comparisons. P values lower than 0.05 were considered significant but values lower than 0.1 are also reported.

Conditioned Avoidance Response (CAR)

The effects of a test drug on conditioned response in rats were evaluated using active avoidance responding test. The apparatus consisted of six identical shuttle boxes (PACS-30, Columbus Instruments, USA). Each stainless steel box was 22.8 cm wide, 48.3 cm long and 27.6 cm high and was divided into two equal-sized compartments, separated by a sliding door end equipped with an overhead lights audio generator. An infrared-type beam assembly was used for detecting subject transfers. Each chamber floor was composed of stainless steel grid wired for presentation of a scrambled electric food shock (0.5 mA).

Rats trained to avoid the foot shock were placed in the experimental chambers for a 3 min. habituation period followed by 50 CAR trials presented on a 15-s variable interval (VI) schedule. Each trial consisted of a 10 s warning tone and stimulus light (conditioned stimulus) followed by 10 s electric shock (0.5 mA). If during the initial 10 s of the trial an animal crossed through the sliding door, the tone and light were terminated, no shock was applied, and the response was considered as “an avoidance response”. If the animal crossed through the sliding door after a foot shock was initiated, the response was considered as an escape response. If the animal did not cross the sliding door the response was considered as “none”. If a response was made during an intertrial interval, it was punished with 0.5 s shock (0.5 mA). The PACS-30 software (Columbus) controlled the sessions and counted the number of trials in which a rat avoided the shock, escaped or did not respond. A stable demonstration of >80% of correct avoidance responses after 14-18 training sessions was a criterion for inclusion in subsequent drug tests. On test days, a tested drug was administered i.p. 60 minutes before the start of the test session. Each drug was tested at 3-4 different doses in the same group of eight animals. A 7-day wash-out period was introduced between the subsequent tests. Two CAR sessions were conducted during the wash-out in order to maintain stable conditioned responding. The number of CAR trials during the test and wash-out sessions was reduced to 30.

›EXAMPLE 9 · 2 of 3

Avoidances, escapes, and “none” responses were analyzed with the aid of a one-way analysis of variance (ANOVA). The Newman-Keuls test was used for individual post hoc comparisons.

Passive Avoidance Procedure

Potentially impairing effects of test substance on learning and memory function in rats were evaluated using a step-through passive avoidance (PA) test. The apparatus consisted of 6 identical shuttle boxes divided into lighted and dark compartments (220×240×270 mm) and equipped with grid floors (PACS-30, Columbus Instruments, USA). The two compartments were separated by a sliding door.

In the training session (acquisition), animals were placed in the lighted compartment and allowed to explore it freely for 10 s. The sliding door was then opened, and the step-through latency for a rat to enter the dark compartment was measured. As soon as the rat entered the dark compartment, the door was closed. Three seconds later, an inescapable foot-shock (0.5 mA for 3 s) was delivered through the grid floor with a constant current shock generator. All animals entered the dark compartment within 300 s (a cut-off) and received a foot-shock.

Rats were pre-injected a test drug 60 minutes before the start of the training session.

The test (expression) session was performed 24 h after the training session. The same procedure was used (see above) but no foot-shock was delivered. A step-through latency for animals to enter the dark compartment was measured with a cut-off of 300 s.

Weights and step-trough latencies were analyzed with the aid of a one-way analysis of variance (ANOVA). The Newman-Keuls test was used for individual post hoc comparisons.

Prepulse Inhibition (PPI) Procedure

The PPI apparatus consisted of eight startle chambers (SR-LAB, San Diego Instruments, San Diego, Calif., USA). Each chamber consisted of a Plexiglas cylinder (8.9 cm diameter×20 cm long) resting on a Plexiglas frame in a sound attenuated, ventilated enclosure. Background noise and acoustic stimuli were presented via a loudspeaker mounted 24 cm above the animal. Startle responses, reflecting the motion of animals in the cylinder so following the acoustic stimulus, were detected by a piezoelectric transducer mounted below the frame. The administration of stimuli and response recording were controlled by the SR-LAB software. Test sessions started with a 5-minutes acclimatization period. Throughout the whole session, the chamber light was on, and the background white noise was set at 70 dB. The test session included 3 initial startling stimuli (intensity: 120 dB, duration: 40 ms) to accustom the rat to the experimental procedure. The initial stimuli were followed by 60 trials (6×10 trials) presented in a random order:

10 background trials (B) which involved a presentation of a sham stimulus (intensity: 70 dB, duration: 40 ms), two types (2×10) of prepulse trials (PP) which included only a prepulse stimuli (84 dB or 90 dB, 20 ms), pulse trials (P) which included only a pulse startling stimulus (120 dB, 40 ms), two types (2×10) of prepulse-and-pulse trials (PP-P) which involved a prepulse (84 db or 90 dB, 20 ms) followed 100 ms later by a 120-dB pulse stimulus (P).

The average inter-trial interval was 22.5 s (range: 15-30 s). This interval was randomized by the SR-LAB software. Startle responses were measured for 100 ms after the onset of the last trial stimulus. For each type of stimulation, startle amplitudes were averaged across the 10 trials. The magnitude of PPI was calculated as a percent inhibition of the startle amplitude in the pulse trial (treated as 100%) according to the formula: [(startle amplitude in P trials−startle amplitude in PP-P trials) startle so amplitude in P trials]×100%. Startle responses to the 3 initial stimuli were excluded from the statistical analyses.

Effects of Tested Compounds on PPI and on Amphetamine-Induced PPI Deficits

Rats were pre-injected with the test drug (60 min.). Each compound was tested in two separate experiments performed over two consecutive days (Experiments 1-2) in separate groups of drug-naive rats. Fifteen minutes before the start of the PPI session, rats were injected with saline (Experiment 1) or amphetamine (Experiment 2).

In Experiment 1, each reference compound, or its vehicle, was given in combination with physiological saline (0.9% NaCl). The purpose of this experiment was to assess effects of the reference drug on basic startle responses and PPI. Results of Experiment 1 determined a range of drug doses tested in Experiment 2. In Experiment 2, the so reference drug, or its vehicle, was administered in combination with amphetamine (6 mg/kg, i.p.). The purpose of Experiment 2 was to assess drugs effects on amphetamine-induced PPI deficits.

Startle responses (in manufacturer's arbitrary units), and magnitudes of PPI (%) were analyzed with the aid of a one-way analysis of variance (ANOVA). The Newman-Keuls is test was used for individual post hoc comparisons.

Forced Swimming Test (The Porsolt's Test)

The animals were individually subjected to two experimental trials during which they were forced to swim in a cylinder (40 cm high, 18 cm in diameter) filled with warm water (25° C.) to a height of 15 cm. A video camera was mounted 50 cm above the cylinder. The first (habituation) and second (test) trial lasted 15 and 5 minutes, respectively. There was a 24-h interval between the trials. The total duration of immobility was measured during the second trial by a trained observer located in a separate room.

Weights and time of immobility were analyzed with the aid of a one-way analysis of variance (ANOVA). The Newman-Keuls test was used for individual post hoc comparisons.

Elevated Plus Maze Test in Rats

The testing procedure was based on a method described by Pellow and File (1986). Plus-maze apparatus (an automated device produced by Kinder Scientific) made of durable, high density, non porous black plastic, elevated to a height of 50 cm, consisted of two open arms (50×10 cm) and two closed arms (50×10 cm, and 30 cm high walls), arranged so that the two arms of each type were opposite each other. Floor of the plus-maze was made of infrared transparent material what means that there are no visible sensors. The plus-maze was placed in a darkened room, and the center of the apparatus was illuminated with a 25 W electric bulb hanging 100 cm above. Plus-maze apparatus was connected to PC software by control chassis. Each rat was gently placed in the center of the plus-maze, facing one of the closed arms, immediately after a 5-min adaptation period in a plastic black box (60×60×35 cm). During a 5-minutes test period, automated Motor Monitor System recorded the number of entries into the closed and open arms, the time spent in and the distance (cm) covered by a rat in either type of the arms. After each trial the maze was wiped clean. All compounds were administered to 5-8 rats per treatment group. Compounds 22 and 36 were administered so 60 minutes before the experiment.

›EXAMPLE 9 · 3 of 3

Conflict Drinking Test (Vogel Test) in Rats

Anxiety Monitoring System “Vogel test” produced by TSE Systems was used. It was consisted of a polycarbonate cage (dimensions 26.5×15×42 cm), equipped with a grid floor made from stainless steel bars and a drinking bottle containing tap water. Experimental chambers (two) were connected to PC software by control chassis and a device that generates electric shocks. On the first day of the experiment, the rats were adapted to the test chamber for 10 min. After the adaptation period, the animals were deprived of water for 24 h and were then placed in the test chamber for another 10-min adaptation period during which they had free access to the drinking bottle. Afterwards, they were allowed a 30-min free-drinking session in their home cage. After another 24-h water deprivation period, the rats were placed again in the test chamber. Recording data started immediately after the first lick and every 20 licks rats were punished with an electric shock (0.5 mA, lasting 1 s). The impulses were released via the spout of the drinking bottle. If a rat was drinking when an impulse was released, it received a shock. The number of licks and the number of shocks received throughout a 5-min experimental session was recorded automatically. Compounds 22 and 36 were administered to 10 rats per treatment group, 60 min before the experiment.

Results of behavioral tests described in Example 8 confirm potential activity of the compounds of invention in therapy of psychotic symptoms.

Data for the representative compound 22 in Examples 8 and 9 show its wide antipsychotic activity in all applied rodent models. It is noteworthy that the compound was active in models utilizing psychotomimetic substances affecting either dopaminergic (d-amphetamine, apomorphine), serotoninergic (DOI) or glutamatergic transmission (MK-801) as well as in specific conditioning procedure (active avoidance response). Compound 22 was active in procedures indicative of efficacy in either so positive symptoms of schizophrenia, such as: d-amphetamine and MK-801 induced hyperlocomotion, stereotyped behavior induced by apomorphine and DOI, active avoidance response, as well as in procedure assessing ability to treat attention deficits and information filtering (dimensions of cognitive deficits), underlying the pathomechanism of schizophrenia—reversal of deficits in prepulse inhibition in rats. Moreover compound 22 was active in well established models for detecting substances with potential antidepressant activity, i.e. tail suspension test in mice and forced swim test (Porsolt) in rats as well as potential anxiolytic activity, i.e. four plates test in mice, elevated plus maze and conflict drinking test (Vogel) in rats. Such a wide pharmacological activity, beyond the purely antipsychotic effects is a particularly so desirable feature of modern antipsychotic drug, considering complexity of clinical conditions associated with schizophrenia, including depression and anxiety.

Data for compound 36 show its wide antidepressant and anxiolytic activity in all applied models in mice and rats (tail suspension test in mice and forced swim test (Porsolt) in rats, four plates test in mice and conflict drinking test (Vogel) in rats). This confirms its potential efficacy in treatment of depression and anxiety, as well as its potential use as add on therapy for currently used antipsychotics in treatment of negative symptoms of schizophrenia.
