Catalog Number: 1254
Chemical Name: trans-4-[(1R)-1-Aminoethyl]-N-4-pyridinylcyclohexanecarboxamide dihydrochloride
Biological Activity
Selective p160ROCK inhibitor (Ki values are 0.14, 26, 25 and > 250 μM for p160ROCK, PKC, PKA and MLCK respectively). Also inhibits PRK2 (IC50 = 600 nM). Smooth muscle relaxant and orally active in vivo. Increases survival rate of human embryonic stem (hES) cells and iPSC-BMECs undergoing cryopreservation. Also optimizes naïve human pluripotent stem cell growth and viability following naïve cell derivation from primed ESCs and iPSCs using naïve human stem cell medium (NHSM).
