RESUMO
The preparation, determination of isomeric configuration, and antifungal properties of (E)-1-(5-chlorothien-2-yl)-2-(1H-imidazol-1-yl)ethanone 2,6-dichlorophenylhydrazone hydrochloride (1) are described. In vitro, compound 1 has been shown to have activity against Candida albicans comparable with miconazole. When administered orally to animals with experimentally induced vaginal candidiasis or systemic candidiasis, compound 1 produced results approaching those produced by ketoconazole. In addition, topical administration of compound 1 to rats with vaginal candidiasis produced results comparable with those produced by similar administration of clotrimazole. Unlike ketoconazole, which is active by a mechanism that is essentially fungistatic, compound 1 shares with miconazole a mode of action that is fungicidal. However, unlike miconazole, compound 1 exhibits activity following oral administration. Compound 1 has been found to be negative in the Ames test.
