Thiazovivin is a highly potent, selective, and cell-permeable small molecule Rock inhibitor with effective cellular activity ~ 2 μM. It can enhance survival of human embryonic stem cells (hESCs) or iPSCs after single cell dissociation by trypsin, and dramatically improve the reprogramming efficiency of iPSC (>200 folds) from human fibroblasts when used in combination with SB431542 and PD0325091. It has been shown to exhibit better activity than Y27632 in many stem cell assays.
