GW788388 is a selective inhibitor of transforming growth factor-β type I receptor (ALK5) (IC50 values are 0.018 and 0.093 μM for ALK5 binding and for TGF-β cellular assay respectively). GW788388 inhibits esophageal squamous cell carcinoma (ESCC)-induced neoangiogenesis. GW788388 is orally available with a half-life of approximately 4 hours. GW788388 blocked TGF-beta-induced Smad activation and target gene expression, while decreasing epithelial-mesenchymal transitions and fibrogenesis. Treatment with GW788388 significantly reduced TGF-beta activity, leading to the attenuation of systolic dysfunction and left ventricular remodeling in an experimental rat model of MI.

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.
