A novel series of 5′-benzylidene-3′-phenylspiro[indoline-3,2′-thiazolidine]-2,4′(1H)-diones 6a-d and spiro[indoline-3,2′-thiazolo[5,4-e]pyrimido[1,2-a]pyrimidin]-2(1H)-one 9a-d derivatives have been synthesized. All the newly synthesized compounds were evaluated for antifungal and anti-candidiasis activity by using Disc Diffusion and Modified Microdilution methods. The antimicrobial experiments have shown that the synthesized compounds demonstrated broad-spectrum antifungal activity in vitro. Among them, compounds 9a-9d had stronger antifungal activity against Trichophyton rubrum, Trichophyton mentagrophytes, and Candida albicans; compounds 6a-d also showed significant antifungal activity against selected fungal strains as compared to ketoconazole, the reference antifungal drug. The evaluation of antifungal activity against drug-resistant fungal variants showed that the designed compounds had significant antifungal activity against the tested variants. The combination of compounds (6a-d) and (9a-d) exhibited that the synthesized compounds had synergistic effects or additive effects. These results demonstrated that the synthesized compounds were putative chitin synthase inhibitors exhibiting broad spectrum antifungal activities. The present results indicate that novel spiro pyrimidine derivatives can be used as an active pharmaceutical ingredient for novel drug candidate for treatment of dermatophytosis and other fungal agents.
