  优化和表征 4-甲基取代的吡唑-3-甲酰胺，产生外周大麻素 1 受体反向激动剂 TM38837

  摘要：

  由相应的 4-氰基甲基吡唑制备了几个系列的用 4-甲基酰胺、4-甲基羧酸和 4-甲基四唑功能化的不同吡唑-3-甲酰胺，并作为大麻素受体 1 (CB1) 拮抗剂和反向激动剂进行了研究，目的是制备化合物与利莫那班相比，CNS（中枢神经系统）介导的副作用更少。对这些化合物的亲脂性、溶解度、CB1 效力、代谢、大脑和肝脏分布以及对饮食诱导小鼠模型体重减轻的影响进行了评估和优化。一些羧酸和四唑被选择为特别有前途的四唑TM38837，随后在各种肥胖动物模型中表现出令人印象深刻的功效，产生显着的体重减轻并改善炎症和葡萄糖稳态的血浆标志物，其剂量显然产生可忽略不计的脑暴露。 TM38837 成为第一个进入临床试验的外周限制性 CB1 拮抗剂或反向激动剂，支持其缺乏 CNS 作用，现在认为非 CNS 介导的功效与高肝脏暴露有关。这为探索非酒精性脂肪肝（NAFLD）和脂肪性肝炎（NASH）等其他适应症提供了机
