derivatives 1c–j, was synthesized, and their affinity towards cannabinoid receptors was determined. Representative terms were evaluated using in vitro tests and isolated organ assays. Among the derivatives, 1d and 1e resulted in the most potent CB1 receptor ligands (KiCB1 = 35 nM and 21.70 nM, respectively). Interestingly, both in vitro tests and isolated organ assays evidenced CB1 antagonist activity
在这项工作中,大麻素受体 1 中性拮抗剂 8-chloro-1-(2,4-dichlorophenyl)-N-piperidin-1-yl-4,5-dihydrobenzo-1H-6-oxa-cyclohepta 的合成[1] ,2-c]pyrazole-3-carboxamide 1a 及其脱氮 N-环己基类似物 1b 已导致对此类化合物的结构-活性研究的深入。合成了一系列新型 1a,b 的 4,5-二氢苯并氧杂环庚吡唑类似物,衍生物 1c-j,并测定了它们对大麻素受体的亲和力。使用体外测试和离体器官分析评估了代表性术语。在衍生物中,1d 和 1e 产生了最有效的 CB1 受体配体(分别为 KiCB1 = 35 nM 和 21.70 nM)。有趣的是,体外试验和离体器官试验都证明了大多数新化合物的 CB1 拮抗剂活性,排除化合物 1e,其显示出 CB1 部分激动剂行为。1b 的 CB1
