c-Fms-IN-10 is the derivative of thieno [3,2-d] pyrimidine, a kinase inhibitor of FMS (Colony-stimulating factor-1 receptor, CSF-1R; IC50: 2 nM) with anti-tumor activity.
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].
