Scientific background

K252a is an alkaloid isolated from Nocardiopisis sp. soil fungi. This ATP analogue is a highly potent cell permeable inhibitor of CaM kinase and phosphorylase kinase (IC50= 1.8 and 1.7 nM respectively). At higher concentrations it is also an efficient inhibitor of serine/threonine protein kinases (IC50 of 10 to 30 nM).1-8It is reported to promote myogenic differentiation in C2 mouse myoblasts5 and has been shown to block the neuronal differentiation of rat pheochromocytoma PC12 cells by inhibition of trk tyrosine kinase activity.9 Paradoxically K252a exerts neurotrophic effects on primary sensory neurons, neuroblastoma cells, PC12 cells, and central neurons.10,11
