Sitravatinib Usage And Synthesis

Description

Sitravatinib is a multi-kinase inhibitor. It inhibits 35 kinases (IC₅₀s = 0.5-5,550 nM) in a panel of 55 receptor tyrosine kinases (RTKs). Sitravatinib reduces proliferation of A-673, LPS141, MPNST, DDLS, and Saos-2 cancer cells (IC₅₀s = 1,750, 340.1, 705.7, 266, and 1,830 nM, respectively) and decreases phosphorylation of insulin-like growth factor 1 receptor (IGF1-R), PDGFRβ, and Akt in these same cells when used at concentrations ranging from 62.5 to 4,000 nM. It decreases tumor growth in LPS141 and MPNST mouse xenograft models when administered at a dose of 15 mg/kg per day.

Description

Sitravatinib, known as MGCD516, is a multikinase (MET, RET, AXL, NTRK1, or NTRK3 genes) inhibitor used in a phase 1/1b clinical trial (NCT02219711) for patients with advanced cancers (NCT02219711).

Uses

MGCD 516 is an intermediate used to prepare substituted thienopyridines as inhibitors of protein tyrosine kinase activity.
