Amuvatinib

Description

Amuvatinib 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.

The Uses of Amuvatinib

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.

What are the applications of Application

Amuvatinib is a multi-targeted tyrosine kinase inhibitor of PDGF and c-Kit

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.
