GSK429286A is a selective inhibitor of ROCK1 and ROCK2 with IC50 values of 14 nM and 63 nM, respectively.

IC50 & Target

IC50: 14 nM (ROCK1), 63 nM(ROCK2)[1].

In Vitro

GSK429286A at 1 μM reduces ROCK2 activity over 20-fold, under conditions in which the only other kinase tested that is significantly inhibited is MSK1 whose activity is reduced ~5-fold. GSK429286A is a more selective ROCK2 inhibitor than the widely utilized ROCK inhibitor Y-27632 as assessed on kinase-specificity panel, and does not significantly inhibit LRRK2 even at doses as high as 30 μM (500-fold higher than IC50 of inhibition of ROCK2). GSK429286A slightly inhibits RSK and p70S6K with IC50 of 0.78 μM and 1.94 μM, respectively. GSK429286A significantly inhibits rat aortic ring dilation with IC50 of 190 nM[2].

In Vivo

GSK429286A has 61% oral bioavailability in male Sprague-Dawley rats. Oral administration of GSK429286A at single doses of 3-30 mg/kg dramatically reduces mean arterial pressure in the spontaneously hypertensive rats (SHRs) in a dose-dependent manner, with a maximum decrease of 50 mmHg after approximately 2 hours treatment at dose of 30 mg/kg[1].

Animal Administration

Rats: Spontaneously hypertensive rats (SHRs) are treated with GSK429286A to establish its effect on mean arterial pressure. Compound is administered by single dose oral gavage (3, 10, 30 mg/kg)[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
