Glesatinib hydrochloride (C09-1134-761)

Glesatinib hydrochloride (MGCD265 hydrochloride) is an orally active, potent MET/SMO dual inhibitor. Glesatinib hydrochloride, a tyrosine kinase inhibitor, antagonizes P-glycoprotein (P-gp) mediated multidrug resistance (MDR) in non-small cell lung cancer (NSCLC).In VitroGlesatinib hydrochloride (MGCD265 hydrochloride; 0.01-5 μM; for 72 hours) results in a dose-dependent inhibition of cancer cell growth and shows the low IC 50 value of 0.08 μM on NSCLC H1299 cells. Glesatinib hydrochloride (0.01, 0.1, 0.5, 1 μM) significantly increases by several-fold the percentage of apoptotic cells in NSCLC H1299 cells. Glesatinib hydrochloride has the cytotoxicity to P-gp overexpressing cancer cells KB-C2, SW620/Ad300, HEK293/ABCB1, and their parent cells KB-3-1, SW620, HEK293 cells with the IC 50 s fell between 5 and 10 μM. Glesatinib hydrochloride (1, 3 μM; 120 mins) increases the intracellular [ 3 H]-Paclitaxel accumulation and inhibits [ 3 H]-Paclitaxel efflux in cancer cell lines overexpressing P-gp. Glesatinib hydrochloride (0-40 μM) stimulates the ATPase activity of P-gp transporters in a dose-dependent manner. MCE has not independently confirmed the accuracy of these methods.
