BMS-754807 is a potent and reversible inhibitor of the type-1 insulin-like growth factor receptor family kinases (Ki, <2 nmol/L). BMS-754807 effectively inhibits the growth of a broad range of human tumor types in vitro, including mesenchymal, epithelial and hematopoietic tumor cell lines (IC50, 5-365 nmol/L). In vitro, BMS-754807 showed a median EC(50) value of 0.62 μM against the PPTP cell lines. BMS-754807 caused apoptosis in a human rhabdomyosarcoma cell line, Rh41, as shown by an accumulation of the sub-G1 fraction, as well as by an increase in poly ADP ribose polymerase and Caspase 3 cleavage. BMS-754807 is active in vivo in multiple xenograft tumor models with tumor growth inhibition ranging from 53% to 115% and at a minimum effective dose of as low as 6.25 mg/kg dosed orally daily. BMS-754807 is currently in phase I development for the treatment of a variety of human cancers.

|Method||IGF1R/IR and AR antagonists|
|Cell Lines||TNBC cell|
|Incubation Time||48 h|
|Results||In this panel of TNBC cell lines, inhibition by BMS-754807 consistently induced cell death. These data suggest that inhibitors targeting IGF1R/IR homo- or heterodimers can prevent TNBC tumor growth.|

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
