Biological Activity

GS-444217 reduces ASK1 phosphorylation and prevents the phosphorylation of MKK3/6, MKK4, p38, and JNK at concentrations of 0.3 μM and above with full suppression of ASK1 activity at 1 μM.

In vivo, GS-444217 reduces oxidative stress (OS)-induced ASK1 signaling in kidney and inhibits acute renal tubular injury in rats. GS-444217 (30 mg/kg) inhibits activation of ASK1, p38, and JNK in rat kidney. GS-444217 has an in vivo EC50 of approximately 1.6 μM for inhibiting the ASK1 pathway in rodent kidney.

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.
