Investigation of 4-position side chains in the indolopyrimidines confirmed that m-bromoaniline was an optimal substituent for potency. Investigation of substitution within the C-(benzo)ring of benzothienopyrimidines confirmed that introduction of an extra ring can change sharply the effects of substituents when compared to similar bicyclic nuclei, and only two substituents were found which even moderately
据报道,基本的苯胺基嘧啶药效基团的几种精制方法是表皮生长因子受体(EGFr)酪氨酸激酶的有效和选择性抑制剂。本文报道了一系列抑制剂,其中一些6,5-双环杂芳族系统通过其C-2和C-3位置与该苯胺嘧啶药效团融合。尽管产生的三轮车并未产生某些(5/6),6,6-双环系统的巨大效能,但最好的三轮车的EGFr TK的IC(50)约为1 nM。对吲哚并嘧啶中4-位侧链的研究证实,间溴苯胺是效力的最佳取代基。
