6-naphthyridin-2(1H)-ones showed broadly similar activity to the analogous pyrido[2,3-d]pyrimidin-7(8H)-ones, whereas the 1, 8-naphthyridin-2(1H)-ones were at least 10(3)-fold less potent. These results, indicating that the 3-aza atom in the pyrido[2, 3-d]pyrimidin-7(8H)-ones is mandatory, whereas the 1-aza atom is not, support the published binding model for these compounds to c-Src (J.

7-取代的3-(2,6-二氯苯基)-1,6-萘啶-2(1H)-ones是有效的蛋白酪氨酸激酶抑制剂,对c-Src具有选择性。化合物的制备方法是:将4,6-二氨基乙醛与2,6-二氯苯基乙腈缩合,并通过在50%氟硼酸水溶液中进行长时间的重氮化,分别将产物的2-和7-氨基分别转化为羟基和氟代。N-甲基化,然后用脂族二胺,芳族胺或其衍生的锂阴离子处理,得到所需化合物。为了评估相关吡啶并[2,3-d]嘧啶-7(8H)-的两个环A氮杂原子对化合物的相对贡献,还制备了所选的异构体1,8-萘啶-2(1H)-对。抑制活性。评价了化合物通过c-Src,FGF-1受体和PDGF-β受体酶防止模型底物磷酸化的能力。总体而言,针对不同激酶的活性具有高度相关性,其中c-Src通常对结构变化最敏感。1,带有基本脂肪族侧链的6-萘啶-2(1H)-one类似物[7-NH(CH(2))(n)()NRR,7-NHPhO(CH(
