GSK429286A is a selective inhibitor of ROCK1 and ROCK2 with IC50 value of 14 nM and 63 nM, respectively [1].

Rho-kinase (ROCK) is a member of AGC (protein kinase A, protein kinase G and protein kinase C) family and plays an important role in promoting actin-myosin-mediated contractile force generation [2].

GSK429286A is a potent ROCK inhibitor and has a different activity with the reported ROCK inhibitor Y27632. Using GST method, it is shown that GSK429286A treatment (10 μM) increased MYPT phosphrylation at Thr850 via inhibiting ROCK which mediated this phosphorylation process [3].

In male Sprague-Dawley rat model with spontaneously hypertensive, oral administration of GSK429286A (30 mg/kg) marks reduced mean arterial pressure and the maximum decreased was as 50 mmHg after nearly 2 h treatment [4].

Cell experiment: [1]

Cell lines

MDA-MB-231 (TRPM7 shRNA) cells and MCF7 (TRPM7 shRNA) cells

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months.

Reaction Conditions

1 μM, 24 hours


GSK429286A caused Rho-kinase inhibition restored serum-induced transwell migration of TRPM7 knockdown cells without affecting MDA-MB-231 control cell migration. Likewise, gap-closure speed of MFC7 TRPM7 shRNA cells was rescued by Rho-kinase inhibition. In contrast to MDA- MB-231 cells, low concentrations of GSK429286A significantly increased gap-closure speed of MCF7 control cells.

Animal experiment: [2]

Animal models

Male Sprague-Dawley rats

Dosage form

Oral gavage, 30 mg/kg


GSK429286A with 61% oral bioavailability, dramatically reduced mean arterial pressure in spontaneously hypertensive rats after oral administration dose-dependently. A maximum decrease of 50 mmHg was observed approximately 2 h after oral administration at 30 mg/kg.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
