| 生物活性 | Y-27632 dihydrochloride is an orally active, ATP-competitive inhibitor of ROCK-I and ROCK-II, with Kis of 220 and 300 nM, respectively. Y-27632 dihydrochloride attenuates Doxorubicin-induced apoptosis of human cardiac stem cells. Y-27632 also suppresses dissociation-induced apoptosis of murine prostate stem/progenitor cells. Y-27632 dihydrochloride primes human induced pluripotent stem cells (hIPSCs) to selectively differentiate towards mesendodermal lineage via epithelial-mesenchymal transition-like modulation. |

| 体内研究 | Y-27632 (5 and 10 mg/kg) significantly prolongs the onset time of myoclonic jerks when compare with saline group. Y-27632 (5 and 10 mg/kg) significantly prolongs the onset time of clonic convulsions when compare with saline group. Treatment with Dimethylnitrosamine (DMN) causes a significant decrease in rat body and liver weight (DMN-S group) compared with control animals (S-S group). Oral Y27632 (30 mg/kg) essentially prevents this DMN-induced rat body and liver weight loss (DMN-Y group). |
| 体外研究 | Y-27632 inhibits the ROCK family of kinases 100 times more potently than other kinases including protein kinase C, cAMP-dependent kinase and myosin light chain kinase. Y-27632 prolongs the lag time and delays the appearance of BrdU-labeled cells in a concentration-dependent manner, delays of about 1 and 4 h are noticed in the Swiss 3T3 cells treated with 10 and 100 μM Y-27632, respectively. Y-27632 promotes neuronal differentiation of adipose tissue-derived stem cells (ADSCs). Compared to 1.0 and 2.5 μM Y-27632 induced groups, percentages of neuroal-like cells achieved a peak in the 5.0 μM Y-27632 induced group. Extracellular matrix (ECM) molecules decreases apoptosis markers and inhibiting the ROCK pathway blocks ECM stimulated actin cortical mat reformation and increases apoptosis in embryonic corneal epithelial cells. |
