  Tyrosine Kinase Inhibitors. 8. An Unusually Steep Structure−Activity Relationship for Analogues of 4-(3-Bromoanilino)-6,7-dimethoxyquinazoline (PD 153035), a Potent Inhibitor of the Epidermal Growth Factor Receptor

  摘要：

  4-(3-Bromoanilino)-6,7-dimethoxyquinazoline (32, PD 153035) is a very potent inhibitor (IC50 0.025 nM) of the tyrosine kinase activity of the epidermal growth factor receptor (EGFR), binding competitively at the ATP site. Structure-activity relationships for close analogues of 32 are very steep. Some derivatives have IC(50)s UP to 80-fold better than predicted from simple additive binding energy arguments, yet analogues possessing combinations of similar phenyl and quinazoline substituents do not show this ''supra-additive'' effect. Because some substituents which are mildly deactivating by themselves can be strongly activating when used in the correct combinations, it is proposed that certain substituted analogues possess the ability to induce a change in the conformation of the receptor when they bind. There is some bulk tolerance for substitution in the 6- and 7-positions of the quinazoline, so that 32 is not the optimal inhibitor for the induced conformation. The diethoxy derivative 56 [4-(3-bromoanilino)-6,7-diethoxyquinazoline] shows an IC50 Of 0.006 nM, making it the most potent inhibitor of the tyrosine kinase activity of the EGFR yet reported.

  4-[(3-bromophenyl)amino]-6,7-dimethoxyquinazoline (4; PD 153035) as an extremely potent (IC(50) 0.025 nM) inhibitor of the tyrosine kinase activity of the epidermal growth factor receptor (EGFR), several fused tricyclic quinazoline analogues have been prepared and evaluated for their ability to inhibit the enzyme. The most potent compound was the linear imidazo[4,5-g]quinazoline (8), which exhibited an IC(50) of 0

  发现4-[（（3-溴苯基）氨基] -6,7-二甲氧基喹唑啉（4; PD 153035）作为表皮生长因子受体酪氨酸激酶活性的极强抑制剂（IC（50）0.025 nM） （EGFR），已经制备了几种稠合的三环喹唑啉类似物，并对其抑制酶的能力进行了评估。最有效的化合物是线性咪唑并[4,5-g]喹唑啉（8），其IC（50）为0.008 nM，可抑制磷脂酶C-gamma-1片段作为底物的磷酸化。虽然8的N-甲基类似物显示出相似的效价，但类似的N- [2-（二甲基氨基）乙基]衍生物效果较差。接下来最有效的化合物是线性吡唑并喹唑啉（19和20）（IC（50）s为0.34和0.44 nM）和吡咯并喹唑啉（21）（IC（50）为0.44nM），而其他几个几何形状类似于8的线性三环系统（三唑并，噻唑并和吡嗪并喹唑啉）的效果则较差。在咪唑并[4,5-g]喹唑啉和吡咯并喹唑啉系列中，相应的角型异构体的效力也远低于
