A novel series of thiophenes having biologically active sulfonamide (2-11), 3-methylisoxazole (12), 4-methoxybenzo[d]thiazole (13), quinoline (14, 15), benzoylphenylamino (16) and anthracene-9,10-dione (17) moieties were prepared. Structures of the newly synthesized compounds were established by elemental analysis and spectral data. All newly synthesized compounds were evaluated for their in vitro anticancer activity against human breast cancer cell line (MCF7). Most of the screened compounds showed cytotoxic activities compared to doxorubicin as a positive control. Compounds 6, 7, 9 and 13 (IC50 values 10.25, 9.70, 9.55 and 9.39 µmol L–1 revealed higher cytotoxic activities than that of doxorubicin (IC50 = 32.00 µmol L). Also, compounds 5, 8 and 10 were found nearly as active as doxorubicin (IC50 values 28.85, 23.48 and 27.51 µmol L–1).
