and the SARaround three key areas: (1) the amine attached to the butynyl linker (R3R4N–); (2) the benzylamine moiety (R1R2N–); and (3) the point of attachment of the benzylamine group (R1R2N– in the ortho, meta, or para positions) was examined. One compound, 4-[3-(4-piperidin-1-yl-but-1-ynyl)-benzyl]-morpholine (9s) was chosen for further profiling and found to be a selective histamine H3 antagonist
制备了一系列(4-氨基丁炔-1-基)苄胺,SAR围绕三个关键区域:(1)与丁炔基连接基(R 3 R 4 N–)相连的胺;(2)苄胺部分(R 1 R 2 N–);(3)检查了苄胺基团的连接点(R 1 R 2 N–在邻位,间位或对位)。选择一种化合物4- [3-(4-哌啶-1-基-丁-1-炔基)-苄基]-吗啉(9s)进行进一步分析,结果发现它是一种选择性的组胺H 3拮抗剂,具有所需的药物-像属性。离体受体占用研究确定口服后9s确实在大鼠的大脑中占据了H 3结合位点。在自然睡眠阶段皮下注射的9s(10 mg / kg)表现出强大的促醒作用。
