KBP-7018
KBP-7018 is an orally active, tyrosine kinase-selective multi-kinase inhibitor with an IC50 value of 10 nM against c-KIT, 7.6 nM against RET, and 25 nM against human PDGFR. KBP-7018 improves survival rates in a mouse model of pulmonary fibrosis. KBP-7018 can be used in research related to idiopathic pulmonary fibrosis.

KBP-7018 potently and selectively inhibits c-KIT (IC50 = 10 nM), RET (IC50 = 7.6 nM) and PDGFR (IC50 = 25 nM) in cell-free kinase assays. Meanwhile, it shows extremely weak inhibitory activity against hERG K+ and exhibits high kinome selectivity[1].
KBP-7018 inhibits h-PDGF-bb-stimulated proliferation of 3T3 fibroblasts in cell-based assays, with an IC50 of 100 nM[1].
KBP-7018 potently inhibits purified PDGFRα (IC50 = 26 nM) and PDGFRβ (IC50 = 34 nM)[2].
KBP-7018 (0.05-80 μM; 10 min) potently inhibits human CYP3A4 (testosterone probe, IC50 = 0.087 μM), weakly inhibits human CYP2C9 (IC50 = 35.2 μM), and shows no inhibitory effect on human CYP1A2, CYP2C19 or CYP2D6 at concentrations up to 80 μM[2].
