GS-444217 是一种有效的，可口服的，选择性 ATP 竞争性凋亡信号调节激酶 1 (ASK1) 抑制剂，IC₅₀ 为 2.87 nM。

GS-444217 is a potent, orally available and selective ATP-competitive inhibitor of apoptosis signal-regulating kinase 1 (ASK1) with an IC 50 of 2.87 nM.

Solid

ASK1 2.87 nM (IC50)

Treatment with 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. GS-444217 (1 μM) reduces ASK1 activity within 5 minutes of addition to the cultures, reaching a maximum level of inhibition by 30 minutes. Removal of GS-444217 from the cultures results in reactivation of ASK1 autophosphorylation within 10 minutes and near-complete recovery 2 hours after drug washout. has not independently confirmed the accuracy of these methods. They are for reference only.

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 EC 50 of approximately 1.6 μM for inhibiting the ASK1 pathway in rodent kidney. has not independently confirmed the accuracy of these methods. They are for reference only.
