The following needs copyediting, relies too much on primary sources, and has unsourced content. Moved here til it can be improved.

General information[edit | edit source]

Y-27632 is a selective rho-associated protein kinase (ROCK) inhibitor, first discovered by Yoshitomi Pharmaceutical Industries[1]. it has been comprehensively used to describe capacity to ROCK2. It's considered as a potential helpful operator.

Y-27632 inhibits both ROCK1 and ROCK2 in vitro, by competing with ATP for binding to the catalytic site.

-Y-27632 improved survival of human embryonic stem cells (ESCs)when they are separated to single cells by forestalling separation prompted apoptosis, along these lines expanding their cloning proficiency[2].

-Embryoid body formation enhanced by using forced aggregation treatment 

-Increases the survival of cryopreserved single human ES cells[3].

Apoptosis of Moses ES-derived neural prevented after transplantation by Y-27632 also improves the survival of human ES cell at the beginning of differentiation process. 

ROCK inhibitor Y-27632 may be used in treating acute corneal endothelial damage(CECs) [4]and cardiac stem cells (CSCs)[5]. also, improve the survival in transplantation of ES cell-determined neural precursors.

Rock1 protein can be identified by Y-27632 and the premier characterization shows that Y-27632 inhibits the ROCK family of kinases 100 times more effectively than other kinases including protein kinase C, cAMP-dependent kinase and myosin light chain kinase (MLCK).

The mechanism and the selectivity of the Rho kinase inhibition of Y-27632 within the group of Rho family activity have not been fully understood.

Mechanisms[edit | edit source]

Y-27632 inhibit ROCK kinase via vie with ATP to bind to the kinases. This selectivity of the Y-27632 to inhibit the kinases various type comes from the variance in their Ki value to the kinases.

  • The first mechanism used to Detect ROCK kinases Labeling by photoactivatable of Y-27632 exclusive cellular binding protein to specific compounds that have a similar cellular action to those compounds.
  • Second, the dominant negative form of ROCK, Y-27632 express certain blocking of stress fiber induction nor neurite retraction[6].
  • Third, Y-27632 added to allow the smooth muscle with ATP to inhibit smooth muscle contraction which Ca21 mediated by ROCK kinase.
