We previously reported diarylurea derivatives as cannabinoid type-1 receptor (CB1) allosteric modulators, which were effective in attenuating cocaine-seeking behavior. Herein, we extended the structure-activity relationships of PSNCBAM-1 (2) at the central phenyl ring directly connected to the urea moiety. Replacement with a thiophene ring led to 11 with improved or comparable potencies in calcium
我们先前曾报道过二芳基脲衍生物是大麻素1型受体(CB1)变构调节剂,可有效减弱可卡因的寻找行为。在这里,我们扩展了PSNCBAM-1(2)在直接连接到脲部分的中心苯环上的构效关系。噻吩环取代导致11在钙动员,[35S]GTPγS结合和cAMP分析方面具有改进或相当的效力,而非芳香环取代则导致调节活性显着降低。这些化合物在[35S]GTPγS结合中没有反向激动作用,这一特征通常被认为会导致不良的精神病学效应。尽管11在大鼠肝微粒体中具有良好的代谢稳定性,但显示出适度的溶解度和血脑屏障通透性。
