3-HydroxyMidostaurin (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-HydroxyMidostaurin is less selective but more cytotoxic than PKC412[1].
3-HydroxyMidostaurin-D5 (CGP52421-D5) is a deuterium-labeled 3-HydroxyMidostaurin which is a metabolite of PKC412. PKC412 effectively inhibits FMS-like tyrosine kinase-3 (FLT3) autophosphorylation (IC50s: 132 nM and 9.8 μM in culture medium and plasma).
(R)-3-HydroxyMidostaurin 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).
