DDD00033325

A cell-permeable, pyrrolidine small molecule that promotes single human embryonic stem cell survival up to 20-fold over background (EC₅₀ = 3.9 M), with equal or higher potency than Y-27632 (Cat. No. 688000) in 5 cell lines (SA461, SA181, SA167, SA121 and SA002) tested at 10 M. An in vitro high-content screening assay, which profiles a panel of more than 70 protein kinases, indicates that this small molecule is more selective than Y-27632 and only displays an inhibitory effect toward ROCK2 (>83% inhibition, ROCK1 was not included in the panel) and PRK2 (76% inhibition) at 10 M. Furthermore, it exhibits less cytotoxicity at a greater concentration of 30 M than Y-27632 without marked adverse effects for up to 120 hours.
