New pyrazoline derivatives bearing an oxadiazole moiety were synthesized via the reaction of 1-(chloroacetyl)-3-(2-furyl/thienyl)-5-aryl-2-pyrazolines with 5-substituted-1,3,4-oxadiazole-2(3H)-thiones in the presence of potassium carbonate. Compounds 1 - 32 were screened for their antifungal activity against various Candida species and compared with ketoconazole. Among these compounds, the most effective derivatives were evaluated for their cytotoxicity against NIH/3T3 cells. 2-({2-[5-(4-Bromophenyl)-3-(2-furyl)-4,5-dihydro-1H-pyrazol-1-yl]-2-oxoethyl}thio)-5-(2-cyclopentylethyl)-1,3,4-oxadiazole (23) can be identified as the most potent antifungal agent against C. tropicalis due to its inhibitory effect on C. tropicalis and low toxicity to NIH/3T3 cells.
