  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.

  小分子磷酸二酯酶探针：发现有效和选择性的CNS穿透性PDE1喹唑啉抑制剂†

  摘要：

  PDE1是在中枢神经系统和周围区域表达的钙激活双底物磷酸二酯酶家族，在细胞内钙和环状核苷酸信号级联反应的整合中发挥作用。由于缺乏有效，选择性和脑穿透性的PDE1抑制剂，阻碍了针对这种酶家族治疗神经精神疾病的潜力的探索。为了鉴定此类化合物，我们使用了高通量筛选，基于结构的设计和针对性的合成化学，以发现4-氨基喹唑啉7a（PF-04471141）和4-茚满基喹唑啉27（PF-04822163）每种都是易于穿越血脑屏障的PDE1抑制剂。这些基于喹唑啉的PDE1选择性抑制剂代表了有价值的新工具，可用于研究PDE1调节的生物学过程并开始确定此类化合物治疗神经精神疾病的潜在治疗作用。
