On account of the reported anticancer activity of pyrazoles and oxadiazoles, we have designed and synthesized a novel combinatorial library of S-substituted-1,3,4-oxadiazole bearing N-methyl-4-(trifluoromethyl)phenyl pyrazole moiety and tested for in-vitro cytotoxic activity by MTT assay. Amongst the tested compounds, the compound 5e was the most promising anticancer agent with IC50 value of 15.54 μM in MCF-7 cells, compared to Doxorubicin as standard drug. The newly synthesized compounds were characterized by NOE, IR, 1H NMR, 13C NMR and LC–MS analysis.
