  摘要：

  进行了我们原始毒蕈碱型M（3）受体拮抗剂1的胺部分的优化，以鉴定出优于1的M（3）受体拮抗剂。对氮原子上带有疏水取代基的各种二胺部分的化合物进行了筛选。 M（3）受体的结合亲和力和M（3）超过M（1）和M（2）受体的选择性。该过程导致了4-氨基哌啶酰胺（2l），其K（i）值为5.1 nM，M（3）受体的选择性比M（2）受体大46倍。通过插入间隔基或将烷基引入胺部分进一步2l衍生化，从而鉴定出K（i）值为3的4-（氨基乙基）哌啶酰胺2l-b。

  Synthesis, biological evaluation and SAR studies of benzimidazole derivatives as H1-antihistamine agents

  摘要：

  A series of benzimidazole derivatives have been designed, synthesized and evaluated for H-1 antihistamine activity. Six compounds have showed potent antihistamine H-1 activity. The primary SAR analysis indicated that benzyl or benzylidinyl substituted on the exo-nitrogen atom and C2 of the benzimidazole were significant. Further experiments indicated that compound 17d displayed excellent activity to reduce mast cell degranulation, moderate anti-PAF activity and decreased potency on hERG compared to astermizole. Hence compound 17d could serve as anti-allergic agent for further development. (C) 2012 Da Li Yin. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
