AMG 458 is a Potent, Selective, and Orally Bioavailable c-Met Inhibitor with Ki=2.0, IC50 (CT26)=120 nM significantly inhibited tumor growth in the NIH3T3/TPR-Met and U-87 MG xenograft models with no adverse effect on body weight.

|Cell Lines||A549 and H441 lung cancer cells|
|Incubation Time||2 h|
|Results||Treatment of H441 cells with 5-mmol/L AMG-458 before radiation caused a significant survival curve shift in H441 cells relative to DMSO-treated cells|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
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.
