(E)-2-(3-(3-((3-Bromophenyl)amino)-2-cyano-3-oxoprop-1-en-1-yl)-1H-indol-1-yl)acetic acid (1) was discovered in a HTS campaign for CRTh2 receptor antagonists. An SAR around this hit could be established and representatives with interesting activity profiles were obtained. Ring closing tactics to convert this hit series into a novel 2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole based CRTh2 receptor antagonist series is presented. (C) 2012 Elsevier Ltd. All rights reserved.
(E)-2-(3-(3-((3-溴苯基)氨基)-2-羰基-3-丙酮-1-烯-1-yl)-1H-苯并azole-1-yl)乙酸(1)在HTS对CRTh2受体拮抗剂筛选中被发现。围绕此初筛物形成的SAR(结构活性关系研究)可以进行,可获得代表活性特性有趣的系列物。通过环闭合策略,将此初筛物系列转化为一种新型的2,3,4,5-四氢-1H-苯并[4,3-b]苯并azole基CRTh2受体拮抗剂系列。2012ElsevierLtd.所有权利保留。
