Activity of two benzofuran-imidazoles, IM/B/4-62 and IM/B/4-66, against experimental infections with Candida albicans and Trichophyton mentagrophytes.

The therapeutic activity of two new benzofuran-imidazoles, IM/B/4-62 and IM/B/4-66, formulated as 1% cream, has been evaluated against Candida albicans and Trichophyton mentagrophytes by inducing experimental vaginal candidosis in female rats and dermatophytosis in female guinea pigs. Results of the treatment were compared with those obtained by the same therapeutic regimen carried out with bifonazole. IM/B/4-66 proved to possess superior antimycotic activity to that of IM/B/4-62 and similar to that of bifonazole in both infections. Nmaley vaginal candidosis was cured in all the treated in animals at 6 days post-inoculation and skin lesions were healed in 9 of 10 animals at 15 days after infection, with negative cultures from all the infected sites.
