›TECHNICAL FIELD

The present invention relates to novel compounds of the Formula (1), containing thieno-[2,3-d]pyrimidin-4(3H)-ones moieties and pharmaceutically acceptable salts thereof, methods for preparing these compounds, the use of these compounds in prevention and treatment of fungal infections, and to pharmaceutical preparations containing these novel compounds.

›BACKGROUND AND PRIOR ART

Fungal infections are the major problem in the treatment of immuno-compromised patients and those suffering from AIDS. The current antifungal agents belong to various groups like polyenes, allylamines, antimetabolites, azoles, glucan synthesis inhibitors etc. Fluconazole is a member of the family of azole antifungals. Fluconazole is orally active and has low toxicity but its extensive use has resulted in emergence of fluconazole-resistant fungal strains. Therefore, it is necessary to meet the long-felt need to develop novel fluconazole analogues which exert high anti-fungal activity against various fungi including Candida albicans, Aspergillus niger and Fusarium proliferatum with MIC values 2 to 8 fold lower than that of fluconazole.

The presence of one triazole ring, halogenated phenyl ring and tertiary alcoholic oxygen functionality in fluconazole is necessary for activity. The present invention seeks to provide novel azoles and process thereof as an effort to come up with antifungal agents with broad spectrum of antifungal activity. Fluconazole analogues have been reported having antifungal activity in the literature.

A series of fluconazole analogues incorporating azaindole and indole moieties were described in “Synthesis and anti-fungal activities of new fluconazole analogues with azoheterocycle moiety”, Bioorg Med Chem Lett 2007 Jul. 1; 17(13), 3686-9.

›OBJECTS OF THE INVENTION

›SUMMARY OF THE INVENTION

Accordingly, to meet the above stated objective, the present invention discloses novel fluconazole analogues of Formula (1) containing thieno-[2,3-d]pyrimidin-4(3H)-one moieties, which are useful as antifungal compounds with MIC values 2 to 8 fold lower than that of fluconazole.

Antifungal Activity Testing

The compounds of Formula 1 are antifungal agents effective against Candida albicans . In vitro evaluation of antifungal activity was performed by determining the minimum inhibitory concentration (MIC). Anti-fungal susceptibility testing of these anti-fungal compounds was done by broth dilution method using RPMI 1640 medium with MOPS buffer. Known anti-fungal agents like fluconazole and amphotericin-B were used as positive control. End points were determined after 48 hours visually and by using spectrophotometer wherever necessary. Different dilutions were, tried and various sets of experiments performed. The activity parameters are enumerated in Table 1:

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative examples and that the present invention may be embodied in other specific forms without departing from the essential attributes thereof, and it is therefore desired that the present embodiments and examples be considered in all respects as illustrative and not restrictive, reference being made to the appended claims, rather than to the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
