pungent alkaloid of black pepper, and several of its derivatives are modulators of gamma-amino butyric acid type A (GABAA) receptors. Concomitantly, this natural product has also been reported to activate transient receptor potential vanilloid type 1 (TRPV1) receptors. We have developed a Heck cross-coupling reaction of conjugated dienamides enabling the rapid assembly of piperine derivatives containing
黑胡椒的刺激性生物碱胡椒碱及其几种衍生物是 γ-氨基丁酸 A 型 (GABAA) 受体的调节剂。同时,据报道,这种天然产物还可以激活瞬时受体电位香草素 1 型 (TRPV1) 受体。我们开发了共轭二酰胺的 Heck 交叉偶联反应,能够快速组装含有改性芳香核心的胡椒碱衍生物。在评估重点化合物库后,确定了关键的芳香族取代基,选择性地影响 GABAA 或 TRPV1 受体。
