Description
Amuvatinib (also known as MP-470 or 850879-09-3), is a multi-targeted inhibitor of receptor tyrosine kinases that inhibits c-Kit, platelet-derived growth factor receptor α (PDGFRα), and c-Met (IC50s = 10, 40, and 81 nM, respectively). It inhibits growth and induces apoptosis in prostate cancer cell lines, with additive effects achieved when combined with erlotinib . Amuvatinib sensitizes cancer cells to radiation and chemotherapeutic compounds, in part by inhibiting homologous recombination.
Uses
MP-470 (Amuvatinib) is a potent and multi-targeted inhibitor of c-KitD816H, PDGFαV561D and Flt3D835Y with IC50 of 10 nM, 40 nM and 81 nM, respectively.
Definition
ChEBI: N-(1,3-benzodioxol-5-ylmethyl)-4-(4-benzofuro[3,2-d]pyrimidinyl)-1-piperazinecarbothioamide is a N-arylpiperazine.
Clinical Use
Amivantamab is the first drug approved by the FDA for the treatment of patients with NSCLC and EGFR exon 20 insertion mutations.
Mode of action
Μechanisticly, amuvatinib inhibits tyrosine kinase receptor KIT through occupying its ATP binding domain (IC50 < 0.1 μM) and disrupts DNA repair through suppression of homologous recombination protein Rad51 as well as synergistic effects in combination with double stranded DNA damaging agents.
