alkyl linker were designed and synthesized. Herein we report the synthesis and structure–activity relationships (SARs) of this novel class of arylthiourea derivatives that showed potent inhibitory activities against HCV in the cell-based subgenomic HCV replicon assay. Among compounds tested, the new carbazole derivative 64, which has an eight-carbon linkage between the phenyl and carbazole rings and a tolyl

The inhibition of the mammalian solubleepoxidehydrolase (sEH) is a promising new therapy in the treatment of hypertension, inflammation, and other disorders. However, the problems of limited water solubility, high melting point, and low metabolic stability complicated the development of 1,3-disubstituted urea-based sEH inhibitors. The current study explored the introduction of the substituted piperazino
Histamine has been converted into a non‐imidazole H3‐receptor histamineantagonist 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。
