AZ12672857 is an orally active inhibitor of EphB4 (IC50=1.3 nM) and Src kinases. AZ12672857 shows good inhibition of proliferation of c-Src transfected 3T3 cells (IC50=2 nM) as well as autophosphorylation of EphB4 in transfected CHO-K1 cells (IC50=9 nM)[1].
AZ12672857 shows only modest inhibition of CYP P450 (IC50=5 μM against 2C9 and 3A4, >10 μM against 1A4, 2D6 and 2C19). AZ12672857 inhibits p-KDR in HUVEC with an IC50 of 240 nM and inhibits p-PDGFR-βin MG63 cell line with an IC50 of 58 nM[1].
