Thiophene derivatives are studied intensively due to their anticancer, antimicrobial, antioxidant and some other clinically important properties. In this study, the biological properties of a new thiophene derivative, so called BMPT, with a moderate drug score of 0.29 were tested. BMPT showed selective cytotoxicity for LnCap, HepG2 and Caco-2 cancer cell lines with EC50 values of 138.573 mu M, 185.931 mu M, and 108.657 mu M, respectively, but not on the control cell line HEK293. The increased expressions were detected for caspase3, caspase8, caspase9 and Bax; but Bcl-2 expressions were decreased at cancer cell lines. BMPT decreased the total thiol content and total GST activities at HepG2 47 % and 40 %, respectively, and, molecular docking supported inhibitory models for GSTP1-1, GSTA1-1 and GSTM2-2 were mixed, uncompetitive and uncompetitive, respectively. BMPT also showed potent antibacterial activity against Staphylococcus aureus. Related with its selective inhibition on GST activities, BMPT is proposed to have significant apoptotic effect leaded by changes, especially, in caspase 3, Bcl-2 and Bax expressions.
