N-8 of the pyrido[2,3-d]pyrimidine core provided several analogues that retained potency, including derivatives that were biased toward inhibition of the TK activity of PDGFr. Analogues of 2a with a 3-thiophene or an unsubstituted phenyl group at C-6 were the most potent inhibitors. Compound 54, which had IC50 values of 31, 88, and 31 nM against PDGFr, FGFr, and c-src TK activity, respectively, was
化合物库的筛选导致鉴定出2-氨基-6-(2,6-二氯苯基)-8-甲基吡啶并[2,3-d]嘧啶(1)作为血小板衍生的生长因子受体的抑制剂( PDGFr),成纤维细胞生长因子受体(FGFr)和c-src酪氨酸激酶(TKs)。用4-(N,N-二乙基氨基乙氧基)苯基氨基取代C-2为1的伯氨基得到2a,其对所有三个TK的活性均大大提高。在目前的工作中,吡啶并[2,3-d]嘧啶核的C-6处的芳族基团和N-8处的烷基基团的变化提供了几种保留效力的类似物,包括偏向于抑制甲壳素的衍生物。 PDGFr的TK活性。2a在C-6处带有3-噻吩或未取代的苯基的类似物是最有效的抑制剂。化合物54的IC50值为31,
