10.0mg/ml Taking the 1 mL working solution as an example, take 10 mg of this product, add it to 1 ml of 15% Captisol+citrate vehicle clear solution, and mix evenly to make it a uniform suspension. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description GSK429286A (RHO-15) is a selective inhibitor of ROCK1 and ROCK2 with IC50 of 14 nM and 63 nM, respectively.
Targets
ROCK1 [1]
(Cell-free assay)		 ROCK2 [2]
(Cell-free assay)
14 nM 63 nM
In vitro 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. [1] 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). Like GSK269962A but not sunitinib, GSK429286A treatment at 10 μM ablates basal or G14V-Rho mutant induced phosphorylation of MYPT at Thr850 in HEK-293 cells to a similar extent as H-1152 and Y-27632, consistent with ROCK mediating this phosphorylation, whereas GSK429286A does not inhibit ERM protein phosphorylation either in the presence or absence of G14V-Rho. [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]
Features Greater selectivity than Y-27632.
