3-arylquinoxalines were prepared and tested for inhibition of platelet-derived growth factor receptor tyrosine kinase (PDGF-RTK) activity. The potency of the inhibitors was found to be quinoxalines > quinolines > indoles. Lipophilic groups (methyl, methoxy) in the 6 and 7 positions and phenyl at the 3 position of quinoxalines and quinolines were essential for potency, in contrast to the hydrophilic catechol
制备了一系列3-吲哚丙烯腈酪氨酸酪蛋白,2-氯-3-苯基喹啉和3-芳基喹喔啉,并测试了其对血小板衍生的生长因子受体酪氨酸激酶(PDGF-RTK)活性的抑制作用。发现抑制剂的效力为喹喔啉>喹啉>吲哚。喹喔啉和喹啉在6和7位上的亲脂基团(甲基,甲氧基)和3位上的苯基对于效价至关重要,而酪蛋白中的亲水邻苯二酚基团在不同位点具有抑制EGFR激酶活性。抑制剂对PDGF具有选择性,对EGF受体和HER-2 / c-ErbB-2受体无活性。
