in the search for effective therapeutic agents. One of these, antagonism of the cannabinoid 1 (CB1) receptor, rose to prominence following reports demonstrating the positive modulation of food intake by the CB1 antagonist, rimonabant (3) (SR141716A). In the present study, various diaryl-pyrazole derivatives containing cycloalkyl building blocks were synthesized and tested for CB1 receptor binding affinities
肥胖是西方世界的主要临床问题,在寻找有效的治疗剂中已经探索了许多分子靶标。其中之一是对大麻素1(CB1)受体的拮抗作用,在有报道表明CB1拮抗剂利莫那班(3)(SR141716A)对食物摄入有积极调节作用后,这种作用日益突出。在本研究中,合成了各种含有环烷基结构单元的二芳基-吡唑衍生物,并测试了其与CB1受体的结合亲和力。彻底的结构-活性关系(SAR)研究优化了吡唑取代基,导致了几种新型的K i CB1拮抗剂≤5 nM,并且与人肝微粒体具有可接受的代谢稳定性。在这些类似物中,我们鉴定出5-(4-环丙基苯基)-1-(2,4-二氯苯基)-4-乙基-N-吡咯烷-1-基-1H-吡唑-3-羧酰胺(11r),它们具有与临床参考文献相比,具有良好的药理作用,在降低代谢综合征的血脂参数方面具有出色的功效。
