In vitro試験 Y-27632 2HCl inhibits ROCK-II while displaying little activity against PKC, cAMP-dependent protein kinase and myosin light-chain kinase (MLCK) with Ki of 26 μM, 25 μM and > 250 μM, respectively, as well as PKA activated by another Rho-family GTPase member, Cdc42. Y-27632 2HCl inhibits smooth-muscle contraction induces by various agonists including phenylephrine, histamine, acetylcholine, serotonin, endothelin, and thromboxane with IC50 of 0.3-1 μM, by selectively inhibiting Ca2+ sensitization. Y-27632 2HCl suppresses Rho-induced, p160ROCK-mediated formation of stress fibres in cultured cells. [1] Y-27632 2HCl treatment blocks both Rho-mediated activation of actomyosin and LPA-stimulated invasive activity of MM1 cells in a concentration-dependent manner. [2] Y-27632 2HCl treatment is not only sufficient to initiate formation of exuberant axonal processes but also facilitates axonal maturation during the very early stages of axonogenesis, while largely sparing axon elongation. [3] In human embryonic stem (hES) cells, Y-27632 2HCl treatment at 10 μM markedly diminishes dissociation-induced apoptosis even in serum-free suspension (SFEB) culture, increases cloning efficiency (from ~1% to ~27%), facilitates subcloning after gene transfer, and enables SFEB-cultured hES cells to survive and differentiate into Bf1+ cortical and basal telencephalic progenitors. [4]
In vivo試験 Oral administration of Y-27632 2HCl at 30 mg/kg significantly decreases the blood pressure in a dose-dependent manner in spontaneous hypertensive rats, renal hypertensive rats, as well as deoxycorticosterone acetate (DOCA)-salt hypertensive rats. [1] When Y-27632 2HCl is continuously administered at a rate of 0.55 μL per hour by implanted pumps for 11 days tumor cell invasion (MM1 cells expressing Val14-RhoA in rats) is significantly delayed. [2] By inhibiting ROCK, Y-27632 2HCl treatment attenuates hypoxia-induced angiogenesis and vascular remodeling in the pulmonary circulation. [5] Pretreatment with Y-27632 has a protective effect against tumor formation in albino mice with Ehrlich ascites carcinoma. [7]

キナーゼアッセイ: [1]

Phosphorylation reactions The p160ROCK is expressed in COS cells as tagged full-length proteins, and immunoprecipitated by the use of anti-tag antibodies. The p160ROCK (30 ng) is incubated with 40 μM [γ-32P]ATP (3.3 Ci/mmol) and with 3 μg of either histone (HF2A), dephosphorylated casein or MBP in the presence of various concentrations of Y-27632 2HCl at 30 °C in a total volume of 31 μL. A 7 μL aliquot is taken at 0, 5, 10, and 20 minutes, mixed with an equal volume of 2 × Laemmli sample buffer, and applied to SDS-PAGE. The gel is stained with Commassie Blue, dried and subjected to analysis by a Bioimage Analyzer BAS2000. The Y-27632 2HCl concentration required to inhibit p160ROCK activity by 50% (IC50 value) is obtained. Ki value is calculated according to the equation, Ki = IC50/(1 + S/Km), where S and Km represent concentrations of and Km value for ATP.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Results In order to assess NCC migration, it measured the ROCK inhibitor Y27632, which could enhanced migration significantly. Remarkably, parallel loss of Xcnn2 through injection of Xcnn2MO reduced the Y27632-enhanced migration.

Concentrations 8 uM
Incubation Time 24 h
Results In mineralizing media, cyclic strain induces a dramatic elongation of cells coupled to F-actin reorganization. It studied the effect of ROCK inhibitors (HA1100 and Y27632) on stretch-induced morphological changes. Treatment with HA1100 and Y27632 completely abolished cell area reduction as well as cell elongation in response to mechanical strain (B). Quantitative analyses of cell area revealed that mechanical strain significantly reduced cell area (A and B). Cells were enlarged and they round up into a more circular shape (C).
