Description

MGCD-265 is a potent, multi-target and ATP-competitive inhibitor of Met, VEGFR1, VEGFR2, VEGFR3, Ron, and Tie2 with IC50 of 1 nM, 3 nM, 3 nM, 4 nM, 2 nM and 7 nM, respectively.

In Vitro

MGCD-265 is a multi-target inhibitor of receptor tyrosine kinases. MGCD-265 potently inhibits Met, Met^Y1235D, Met^M1250T, VEGFR1, VEGF2, VEGF3, Ron, and Tie2, with IC50 values ranging from 1 nM to 7 nM. ^[1]MGCD-265 inhibits cell proliferation both in c-Met-driven tumor cells (MKN45, MNNG-HOS, and SNU-5) and in non-c-Met-driven tumor cells (HCT116 and MDA-MB-231), with IC50 values of 6 nM–30 nM and 1 μM–3 μM, respectively. In serum starved MKN45 cells, MGCD-265 (40 nM–5 μM) effectively inhibits c-Met phosphorylation and its downstream signaling pathways, including Erk, Akt, Stat3, and Fak. MGCD-265 (6 nM–1 μM) also induces apoptosis in MKN45 cells. ^[2]

In Vivo

In c-Met-driven or non-c-Met-driven mice xenograft models of MKN45, U87MG, MDA-MB-231, COLO205, and A549 tumor cells, MGCD-265 (20 mg/kg–60 mg/kg) inhibits tumor growth and c-Met signaling. MGCD-265 (40 mg/kg) also downregulates genes involved in angiogenesis, including VEGF and IL-8, both in tumor and plasma of mice with U87MG xenograft. MGCD-265 also inhibits the plasma level of shed-Met. ^[2]

Clinical Trials

A Phase I clinical trial of MGCD-265 in advanced malignancies has been completed. Currently, MGCD-265, in combination of erlotinib or docetaxel, is under investigation in a Phase I/II clinical trial for advanced malignancies or non-small cell lung cancer.
