Biological Activity for Y-27632 dihydrochloride

Y-27632 dihydrochloride is a selective ROCK inhibitor (K_i 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 CHIR 99021, 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. Also used in a protocol to generate brain organoids from human iPSCs. Cell-permeable, orally bioavailable and active in vivo.

Y-27632 in solution and Y-27632 synthesized to cGMP guidelines also available.

Scientific Data Examples for Y-27632 dihydrochloride

	Application of Y-27632 in MESP1+ Mesoderm. ROCK inhibition by Y-27632 (1 μM) promotes skeletal myogenic differentiation of MESP1+ mesoderm, as shown by immunostaining for Myosin Heavy Chain+ (Green) and Myogenin (Red), and counterstaining with DAPI (Catalog # 5748; Blue, Tocris).
