Abstract: AimA series of triazole antifungals were synthesized to search for novel triazole antifungals with more potent activity, less toxicity and broader spectrum. MethodsNineteen 1-(1,2,4-triazolyl-1H-1-yl)-2-(2,4-diflurophenyl)-3-(4-substituted benzyl-1-piperazinyl)-2-propanols were designed and synthesized, on basis of the three dimensional structure of P450 cytochrome 14α-sterol demethylase(CYP51) and their antifungal activities were also evaluated. ResultsAll the title compounds were first reported. Results of preliminary biological tests showed that most of the title compounds exhibited high activity against the eight common pathogenic fungi and the activities against deep fungi were higher than that against shallow fungi. ConclusionMost of the title compounds showed higher antifungal activities than Fluconazole and Terbinafine. Compound VIII-1, 10, 12, 17 showed best antifungal activity with broad antifungal spectrum and were chosen for further development.
