Y-27632 dihydrochloride, Tocris Bioscience™

Y-27632 dihydrochloride is a selective ROCK inhibitor (Ki values are 0.14-0.22, 0.3, 25, 26 and > 250 μM for ROCK1 (p160 ROCK), ROCK2, PKA, PKC and MLCK respectively). Also inhibits PRK2 (IC50 = 600 nM). Increases survival rate of human embryonic stem (hES) cells and iPSC undergoing cryopreservation. Used in combination with CHIR99021, RepSox, Forskolin, SP 600125, Go 6983 and VPA to reprogram fibroblasts to mature neurons. Also optimizes naive human pluripotent stem cell growth and viability following naive cell derivation from primed ESCs and iPSCs using naive human stem cell medium (NHSM). Used as component of growth media for urothelial organoids. Cell-permeable, orally bioavailable and active in vivo. Y-27632 synthesized to cGMP guidelines also available.
