A set of CB2R ligands, based on the thiophene scaffold, was synthesized and evaluated in in vitro assays. Compounds 8c-i, k, l, bearing the 3-carboxylate and 2-(adamantan-1-yl)carboxamido groups together with apolar alkyl/aryl substituents at 5-position or at 4- and 5-positions of the thiophene ring possess high CB2R affinity at low nanomolar concentration, good receptor selectivity, and agonistic
合成了一组基于
噻吩骨架的CB2R
配体,并在体外分析中进行了评估。在
噻吩环的5-位或4-和5-位带有3-
羧酸根和2-(
金刚烷-1-基)羧酰胺基以及非极性烷基/芳基取代基的化合物8c-i,k,l具有在低纳摩尔浓度下具有高CB2R亲和力,良好的受体选择性和激动性功能活性。在过敏性接触性皮炎的实验模型中对全受体激动剂8g(在受体亲和力和选择性之间取得了最佳平衡)进行了体外测试,结果证明能够以10μM的浓度阻断HaCaT细胞中MCP-2的释放。
