Histamine has been converted into a non‐imidazole H3‐receptor histamine antagonist by addition of a 4‐phenylbutyl group at the Nα‐position followed by removal of the imidazole ring. The resulting compound, N‐ethyl‐N‐(4‐phenylbutyl)amine, remarkably has a Ki = 1.3 μM as an H3 antagonist. Using this as a lead compound, a novel series of homologous O and S isosteric tertiary amines was synthesised and
通过在 Nα-位添加 4-苯基丁基,然后去除咪唑环,组胺已转化为非-咪唑 H3-受体组胺拮抗剂。所得化合物 N-乙基-N-(4-苯基丁基)胺作为 H3 拮抗剂具有显着的 Ki = 1.3 μM。使用它作为先导化合物,合成了一系列新的同源 O 和 S 等排叔胺,结构-活性研究提供了 N-(5-苯氧基戊基)吡咯烷(Ki = 0.18 ± 0.10 μM,用于 [3H] 组胺从大鼠中释放大脑皮层突触体),更重要的是,它在体内是活跃的。将 NO2 取代到苯氧基的对位得到 N-(5-p-硝基苯氧基戊基)吡咯烷,UCL 1972 (Ki = 39 ± 11 nM),ED50 = 1.1 ± 0.6 mg / kg per os in 脑远程小鼠甲基组胺水平。
