K252a is an alkaloid isolated from Nocardiopisis bacteria. This staurosporine analog is a highly potent cell permeable inhibitor of CaM kinase and phosphorylase kinase (IC50 = 1.8 and 1.7 nmol/L, respectively). At higher concentrations it is also an efficient inhibitor of serine/threonine protein kinases (IC50 of 10 to 30 nmol/L).[2][3][4][5][6][7][8][9]

K252a is reported to promote myogenic differentiation in C2 mouse myoblasts[6] and has been shown to block the neuronal differentiation of rat pheochromocytoma PC12 cells by inhibition of trk tyrosine kinase activity.[10]

K252a has been reported in preclinical research as a potential treatment for psoriasis [11]

K252a inhibits tyrosine phosphorylation of Trk A induced by NGF. PC12 cells were incubated in the presence or absence of 10 ng/ml NGF with or without various concentrations of K252a.
