BMS-754807 (C09-0785-291)

InformationBMS-754807 is a potent and reversible inhibitor ofIGF-1R/InsRwithIC50of 1.8 nM/1.7 nM in cell-free assays, less potent to Met (c-Met), Aurora A/B, TrkA/B and Ron, and shows little activity to Flt3, Lck, MK2, PKA, PKC etc. Phase 2.In vitroBMS-754807 effectively inhibits the growth of a broad range of human tumor cell lines of different histologic origins including mesenchymal (Ewing/'s, rhabdomyosarcoma, neuroblastoma, and liposarcoma), epithelial (breast, lung, pancreatic, colon, and gastric), and hematopoietic (multiple myeloma and leukemia), the IC50 values range from 5 nM to 365 nM for the most sensitive cell lines. BMS-754807 inhibits proliferation of IGF-1R-Sal cells and RH41 cells with IC50 of 7 nM and 5 nM. BMS-754807 inhibits phosphorylation of IGF-1R in IGF-1R-Sal cells, Rh41 and Geo with IC50 of 13 nM, 6 nM and 21 nM. BMS-754807 inhibits phosphorylation of Akt in IGF-1R-Sal cells, Rh41 and Geo with IC50 of 22 nM, 13 nM and 16 nM. BMS-754807 induces greater apoptosis in Rh41 cells by 24 hours as indicated by an increased sub-G1 peak (23.1%), compared with control (2.4%). BMS-754807 inhibits the phosphorylation of IGF-1R (IC50 = 13nM) and the downstream targets Akt (IC50 = 22nM) and MAPK (IC50 = 13nM) in the IGF-Sal cell line with IC50 consistent with the antiproliferative IC50 (7 nM) in this cell line. The crystal structure of BMS-754807 cocrystallized with the kinase domain of IGF-1R shows that the donor/acceptor/donor hydrogen bond triad with Met1052 and Glu1050 within the hinge region of the kinase. BMS-754807 shows a median EC50 value of 0.62 μM against 23 cell lines in the pediatric preclinical testing program (PPTP).In vivoBMS-754807 (12.5mg/kg, orally) inhibits IGF-1R phosphorylation in tumor and serum in IGF-1R-Sal tumor–bearing nude mice. BMS-754807 inhibits tumor growth in a selected group of epithelial (IGF-1R-Sal, GEO, and Colo205), hematopoietic (JJN3), and mesenchymal (RD1 and Rh41) xenograft tumor models with TGI ranging from 53% to 115%. BMS-754807 (6.25 mg/kg) achieves complete tumor growth inhibition in the transgenic-derived IGF-Sal tumor mouse model with correlated inhibition of pIGF-1R and pAKT. The protein binding for BMS-754807 ranges from of 98.5% in mouse plasma to 95.9% in human plasma. BMS-754807 results in clearance of 113 (mL/min)/kg, 20 (mL/min)/kg, 3.5 (mL/min)/kg and 41 (mL/min)/kg. BMS-754807 (25/u2009mg/kg) significantly inhibits tumor in KT-5 (Wilms), KT-14 (rhabdoid), Rh28 (rhabdomyosarcoma), and OS-1 xenografts mice model.Cell Datacell lines：Concentrations：365 nMIncubation Time：72 hoursPowder Purity:≥99%.
