Objective To synthesize a new series of triazole compounds with naphthalene benzyl as side chain and evaluate the antifungal activity. Methods Nine title compounds were synthesized and determined by the ¹H NMR and MS spectra. According to the method recommended by the national committee for clinical laboratory standards(NCCLS), the RPMI-1640 test medium was used,the antifungal activities of all the compounds were evaluated against eight human pathogenic fungi in vitro. Results The title compounds exhibited potent antifungal activities. Compound 1c showed high activities against 7 funguses except Aspergillus fumigatus with the MIC₈₀ values less than 0.125 μg/ml, which was 16 times higher than that of Voriconazole. Conclusion The title compounds with naphthalene and alkyl substituent showed potent antifungal activities.
