摘要: Abstract Based on the roles of Raf1 and JNK1 in hepatocarcinoma development, scaffold-based drug design was employed to produce a series compounds, which subsequently were synthesized explored as potential dual inhibitors kinases for anti-tumor treatment. The compound 1-(3-chloro-4-(6-ethyl-4-oxo-4 H -chromen-2-yl)phenyl)-3-(4-chloro-phenyl)urea ( 3d ) showed 66%, 67% 13% inhibition rate at 50 μM against Raf1, p38-alpha, respectively, but no effect ERK1 ERK2, inhibited expression pERK1/2 markedly HepG2 cells proliferation with IC 50 8.3 μM. Furthermore, lower toxicity normal liver cell-lines QSG7701 HL7702. Molecular docking study further that can fit into binding domain Raf1. Our data suggested activities associated kinases.
