COX/5-LO-IN-2 is a COX2, EGFR, COX1, 5-LOX, BRAF and FAK inhibitor with IC50 of 1.22 µM, 2.5 µM, 2.95 µM, 4.65 µM, 7.4 µM, 12.2 µM, respectively. COX/5-LO-IN-2 induces cell growth arrest at G2/M phase. COX/5-LO-IN-2 triggers apoptotic activity by up-regulating proapoptotic proteins p53, Bax, and caspase-7 and down-regulating anti-apoptotic protein Bcl-2. COX/5-LO-IN-2 can be used for the research of breast cancer[1].
