GSK-25

GSK-25 is a potent, selective and orally bioavailable ROCK1 inhibitor (IC50=7 nM). GSK-25 maintains good selectivity against a panel of 31 kinases (>100 fold), as well as RSK1 and p70S6K (RSK1: IC50=398 nM, p70S6K: IC50=1 μM). GSK-25 inhibits P450 profile (IC50s of 2.5, 5.2, 2.5 µM for CYP2C9, CYP2D6, CYP3A4, respectively).

How to use

In Vitro:

GSK-25 (Rat aorta IC50=256 nM) is profiled in a spontaneously hypertensive rat (SHR) model of hypertension. At 30 mg/kg (p.o.), GSK-25 induces a 25 mmHg (t=3 hours) drop in blood pressure. GSK-25 has promising oral bioavailability (49% in male Sprague-Dawley rats and 19% in monkey), good half-life (1.8 hours in rat and 2.2 hours in monkey).
