Biological Activity for CS 640

CS 640 is a potent calmodulin-dependent kinase I (CaMKI) inhibitor (IC50 values are 1 nM, 1 nM, 3 nM and 8 nM at CAMK1A, CAMK1G, CAMK1B and CAMK1D respectively). Improves insulin sensitivity and glucose control in a mouse model of diet-induced obesity. Orally bioavailable in rodents.
