In the present study, some isoxazole-(benz)azole derivatives (3a–3j) were synthesized by considering antimicrobial and anticancer potencies of azole compounds. Chemical structures of obtained compounds (3a–3j) were confirmed by the data of spectral and elemental analyses. Anticancer activity evaluation was performed at two steps. Initially, cytotoxic effects of the compounds (3a–3j) on HT-29 (colon
