IHMT-15137
IHMT-15137 is a BMX inhibitor with an IC50 of 26.97 nM. IHMT-15137 covalently binds to BMX Cys496 within the ATP-binding pocket, inhibits BMX phosphorylation at Tyr566, and disrupts the BMX-ERK1/2-Cyclin D1/CDK4/6-E2F1 signaling axis. IHMT-15137 reduces E2F1 protein stability via decreased Ser332/337 phosphorylation, increased ubiquitination, and ubiquitin-proteasome pathway degradation. IHMT-15137 induces cell cycle arrest, apoptosis, DNA damage, and suppresses cell migration and invasion. IHMT-15137 can be used for the research of small cell lung cancer.

Biological Activity
IHMT-15137 (3 μM; 24-168 h) synergizes with cisplatin (5-30 μM) to reduce viability, induce S-phase cell cycle arrest, suppress proliferation, promote apoptosis, increase DNA damage, and disrupt the BMX-ERK1/2-Cyclin D1-E2F1 signaling axis in SCLC patient-derived cells C23084 and LUC22009[1].
IHMT-15137 potentiates the cytotoxic and antiproliferative effects of Cisplatin + Etoposide (HY-13629) chemotherapy in SCLC patient-derived cells C23084 and LUC22009[1].
