Biological Activity

Description GSK269962A HCl is a selective ROCK(Rho-associated protein kinase) inhibitor with IC50 values of 1.6 and 4 nM for ROCK1 and ROCK2, respectively.
Targets
ROCK1 [1]
(Cell-free assay)		 ROCK2 [1]
(Cell-free assay)		 MSK1 [1]
(Cell-free assay)		 RSK1 [1]
(Cell-free assay)
1.6 nM 4 nM 49 nM 132 nM
In vitro GSK269962A completely abolished the actin stress fiber formation induced by angiotensin II in human smooth muscles. Such suppressive effect on actin fiber formation was observed beginning at around 1 μM GSK269962A. GSK269962A induced vasorelaxation in preconstricted rat aorta(tissue baths) with an IC50 of 35 nM. the relaxation induced by GSK269962A is reversible. GSK269962A suppressed IL-6 mRNA transcription and reduced LPS-induced IL-6 and TNF-α protein production in macrophages[1].
In vivo Oral administration of GSK269962A produced a profound dose-dependent reduction of systemic blood pressure in spontaneously hypertensive rats. The reduction of blood pressure was acute and substantial. The maximal effect on blood pressure was observed approximately 2 h after oral gavages. The reduction of blood pressure was accompanied by an acute, dose-dependent increase in heart rate, presumably due to the activation of baroreflex mechanism[1]. ROCK inhibition with the use of GSK 269962 in the 10 mg/kg dose, in turn, triggered an increase in VV(voided volume), PVR(post-void residual), VT(volume threshold), VE(voiding efficiency), ICI(intercontraction interval), BC(bladder compliance), and VTNVC(volume threshold to elicit NVC). The inhibition of the ROCK pathway through GSK 269962 appeared to have no effect on either HR(heart rate), SBP(systolic blood pressure), MBP(systolic blood pressure), or DBP(diastolic blood pressure)[2]. NVC:nonvoiding contractions.

Protocol (from reference)

Cell Assay:[1]
  • Cell lines

    Human primary smooth muscle cells

  • Concentrations

    3 μM

  • Incubation Time

    150 min

  • Method

    Human primary smooth muscle cells were serum-starved(cells were grown on coverslips, and at approximately 50% confluence, they were serum-starved overnight) and stimulated with AngII (100 nM) for 2 h. ROCK inhibitors (3 μM for SB-772077-B or GSK269962A) were added 30 min before AngII stimulation, and cells were fixed and stained with rhodamine phalloidin. Confocal images of actin stain were obtained.
Animal Study:[2]
  • Animal Models

    female Wistar rats

  • Dosages

    5 or 10 mg/kg

  • Administration

    intra-arterially
