SMILES: O=C(NC1)C2=C1C3=C4C5=C2C6=C(C=CC=C6)N5[C@](C[C@]7(O)C(OC)=O)([H])O[C@]7(C)N4C8=C3C=CC=C8
Biological Activity: K-252a, a staurosporine analog, inhibits protein kinase, with IC50 values of 470 nM, 140 nM, 270 nM, and 1.7 nM for PKC, PKA, Ca2+/calmodulin-dependent kinase type II, and phosphorylase kinase, respectively[1][2]. K-252a is a potent inhibitor (IC50 of 3 nM) of the tyrosine protein kinase (TRK) activity of the NGF receptor gp140trk, the product of the trk protooncogene[3].
