Description
OverviewA cell-permeable aminothiazolo-carboxamide compound that is ~5-fold more potent than Y-27632 (Cat. Nos. 688000 & 688001) as a ROCK inhibitor (71% inhibition at 2 µM). Effectively prevents trypsinization-induced apoptosis in hESC cultures by stabilizing newly synthesized cell surface E-cadherin and cell-cell adhesion. Unlike, Ptn (Cat. No. 544049), Tzv protects dissociated hESCs even in the absence of ECM. Greatly augments SB431542 (Cat. No. 616461) and PD0325901 (Cat. No. 444966) in improving iPSCs generation efficiency from 4-TF- (Oct44, Klf4, Sox2, and c-Myc) transfected fibroblast cultures.

SynonymsN-Benzyl-2-(pyrimidin-4-ylamino)thiazole-4-carboxamide, Induced Pluripotent Stem Cells Induction Enhancer, Rho Kinase Inhibitor XII
DescriptionA cell-permeable aminothiazolo-carboxamide compound that is ~5-fold more potent than Y-27632 (Cat. Nos. 688000 & 688001) in inhibiting ROCK enzymatic activity (71% inhibition at 2 µM). Single-cell dissociation of cultured hESCs is demonstrated to hyperactivate Rho-ROCK signaling and result in cell death, while suppression of such hyperactivation by Tzv (2 µM) or Y-27632 (2 µM) stabilize newly synthesized cell surface E-cadherin, which in turn promotes cell-cell adhesion and prevents trypsinization-induced apoptosis (12% vs 81% TUNEL-positive cells after trypsinization in matrigel cultures with 2 µM Tzv or DMSO, respectively). Unlike, Ptn (Cat. No. 544049), Tzv protects dissociated individual hESCs even in the absence of ECM (24% vs 90% TUNEL-positive cells after trypsinization in non-coating plates with 2 µM Tzv or Ptn, respectively). Simultaneous blockage of TGFβ and MEK-ERK pathways by 2 µM SB431542 (Cat. No. 616461) and 0.5 µM PD0325901 (Cat. No. 444966) is reported to result in >50-fold improvement of human iPSCs (induced Pluripotent Stem Cells) generation from fibroblast cultures virally transfected with 4-TF (Oct44, Klf4, Sox2, and c-Myc), while the inclusion of 0.5 µM Tzv on top of SB431542 and PD0325901 is demonstrated to further improve the efficiency to an overall improvement of >200-fold from 4-TF-induction alone.
