we reported the inhibition profiles of 4′‐acylpyrrole–5‐fluoroindolin‐2‐one 3 with a C‐3′ side chain for VEGFR2, PDGFR‐β, and FGFR‐1 protein kinases. The pyrrole‐fused cyclohexanone moiety provided 3 with the best potency to inhibit the three kinases, and the C‐3′ side chains contributed to the different inhibition profiles of 3. Compound 3b with a C‐3′ 2‐carboxylethyl side chain showed good potency
在这项研究中,我们报道4'-酰基吡咯-5-氟二氢-2-酮的抑制谱3与C-3'侧链VEGFR2,PDGFR-β,和FGFR-1蛋白激酶。吡咯-稠合的环己酮部分设置3具有抑制三种激酶最好的效力,并促成的不同抑制谱的C-3'侧链3。具有C- 3'2-羧乙基侧链的化合物3b对这三种激酶显示出良好的效价(IC 50:25–260 nM),具有N,N-二烷基-2-氨基甲酰基乙基侧链的化合物3g具有更高的活性。 VEGFR2(IC 50:59纳米)和PDGFR-β(IC 50:16 nM)比FGFR-1(IC 50:1.7μM)。C- 3'3- (二烷基氨基)丙基侧链可作为选择性PDGFR-β抑制剂在3h – j内完成(IC 50:7.8–13 nM)。对化合物3b进行了进一步研究,发现它具有抑制VEGF和FGF依赖性细胞增殖的作用,并具有中等的体内抗癌活性。从对接模拟结果表明的相互作用3B与VEGFR
