cgp-52421

3-Hydroxy Midostaurin (CGP 52421), a metabolite of PKC412, effectively inhibits FMS-like tyrosine kinase-3 (FLT3) autophosphorylation with IC50s of approximately 132 nM and 9.8 μM in culture medium and plasma, respectively. 3-Hydroxy Midostaurin is less selective but more cytotoxic than PKC412[1].

(S)-3-Hydroxy Midostaurin is a potent inhibitor of kinases(IC50 of <400 nM for 13 kinases (VEGFR-2, TRK-A, FLT3, et)).

(R)-3-Hydroxy Midostaurin is a potent inhibitor of kinases,is a major metabolite of midostaurin undergoing by the hepatic CYP3A4 enzyme,has the potential for acute myeloid leukemia (AML).
