AMG 925 is a dual inhibitor of FMS-related tyrosine kinase 3 (FLT3) and cyclin-dependent kinase 4 (Cdk4; IC50s = 1 and 3 nM, respectively). It is selective for FLT3 and Cdk4 over Cdk1 (IC50 = 2.22 μM). AMG 925 also binds to FLT3ITD, FLT3D835Y, FLT3D835H, FLT3K663Q, and FLT3N841I (Kds = 1-4 nM). It inhibits proliferation of MOLM-13, COLO 205, and U937 cancer cells (IC50s = 19, 55, and 52 nM, respectively). AMG 925 (50, 75, and 150 mg/kg) reduces intratumor levels of pSTAT5 and pRb and inhibits tumor growth in a MOLM-13 acute myeloid leukemia (AML) mouse xenograft model.
AMG 925 is a FLT3 and CDK4 Dual Kinase Inhibitor with Preferential Affinity for the Activated State of FLT3.
ChEBI: AMG-925 is an organic heterotricyclic compound that is 9H-pyrido[4',3':4,5]pyrrolo[2,3-d]pyrimidine which is substituted by a [6-(hydroxyacetyl)-5,6,7,8-tetrahydro-1,6-naphthyridin-2-yl]nitrilo group at position 2 and by a trans-4-methylcyclohexyl group at position 9. It is a FLT3 and CDK4 dual kinase inhibitor that has antineoplastic activity. Currently under clinical investigation in patients with relapsed or refractory acute myeloid leukemia (AML). It has a role as an antineoplastic agent, an apoptosis inducer, an EC 2.7.11.22 (cyclin-dependent kinase) inhibitor and an EC 2.7.10.1 (receptor protein-tyrosine kinase) inhibitor. It is a secondary amino compound, a tertiary amino compound, a naphthyridine derivative, a primary alpha-hydroxy ketone and an organic heterotricyclic compound.
