Biological Activity for CDK8/19i

CDK8/19i is a potent and selective CDK8 and CDK19 inhibitor (IC₅₀ values are 2.9 and 14.1 nM, respectively). CDK8/19i maintains pluripotency of mouse PSCs in culture. It induces the formation of dome-shaped colonies and upregulates Nanog-GFP reporter and endogenous Nanog expression in mouse ESCs in vitro.
