Cenisertib (AS-703569) is a multi-kinase inhibitor that blocks the activity of Aurora-kinase-A/B, ABL1, AKT, STAT5 and FLT3. Cenisertib induces major growth-inhibitory effects by blocking the activity of several different molecular targets in neoplastic mast cells (MC)[1]. Cenisertib inhibits tumor growth in xenograft models of pancreatic, breast, colon, ovarian, and lung tumors and leukemia[2]. Aurora-A Aurora-B ABL1 Akt STAT5

Cenisertib (AS-703569) (1-1000 nM; for 48 hours) induces dose-dependent inhibition of proliferation in primary neoplastic mast cells (MC) [1].Cenisertib (5-100 nM; for 24 hours) induces a substantial G2/M cell cycle arrest at low nanomolar concentrations in all MC lines[1].Cenisertib (1-1000 nM; for 24 hours)induces apoptosis in HMC-1.1, HMC-1.2, C2, and NI-1 cells in a dose-dependent manner[1].Cenisertib (5-500 nM; for 24 hours) induces cleavage of caspase 3 in both HMC-1 sub-clones as well as in C2 and NI-1 cells[1]. Cell Proliferation Assay[1] Cell Line: HMC-1.1, HMC-1.2, ROSAKIT WT, ROSAKIT D816V and MCPV-1.1 mast cells

Cenisertib (AS-703569) (orally; 7 or 10 mg/kg/day; for 3 days) significantly suppresses tumor growth. Animal Model: Female CB17 Severe Combined Immunodeficiency (SCID) mice bearing NCI-MDR tumors[2]
