  7-Alkyl-3-benzylcoumarins: A Versatile Scaffold for the Development of Potent and Selective Cannabinoid Receptor Agonists and Antagonists

  摘要：

  A series of 7-alkyl-3-benzylcoumarins was designed, synthesized, and tested at cannabinoid CB1 and CB2 receptors in radioligand binding and cAMP accumulation studies. 7-Alkyl-3-benzylcoumarins were found to constitute a versatile scaffold for obtaining potent CB receptor ligands with high potency at either CB1 or CB2 and a broad spectrum of efficacies. Fine-tuning of compound properties was achieved by small modifications of the substitution pattern. The most potent compounds of the present series include 5-methoxy-3-(2-methylbenzyl)-7-pentyl-2H-chromen-2-one (19a, PSB-SB-1201), a selective CB1 antagonist (K-i CB1 0.022 mu M), 5-methoxy-3-(2-methoxybenzyl)-7-pentyl-2H-chromen-2-one (21a, PSB-SB-1202), a dual CB1/CB2 agonist (CB1 K-i 0.032 mu M, EC50 0.056 mu M; CB2 K-i 0.049 mu M, EC50 0.014 mu M), 5-hydroxy-3-(2-hydroxybenzyl)-7-(2-methyloct-2-yl)-2H-chromen-2-one (25b, PSB-SB-1203), a dual CB1/CB2 ligand that blocks CB1 but activates CB2 receptors (CB1 K-i 0.244 mu M; CB2 K-i 0.210 mu M, EC50 0.054 mu M), and 7-(1-butylcyclopentyl)-5-hydroxy-3-(2-hydroxybenzyl)-2H-chromen-2-one (27b, PSB-SB-1204), a selective CB2 receptor agonist (CB1 K-i 1.59 mu M; CB2 K-i 0.068 mu M, EC50 0.048 mu M).

  香豆素衍生物作为大麻素受体拮抗剂和反向激动剂的合成及药理评价

  摘要：

  在本研究中，我们使用取代的水杨醛和α，β-不饱和醛衍生物作为起始化合物，利用最近开发的本体化多米诺反应合成了36种香豆素和2 H-色烯衍生物。在放射性配体结合研究中，5取代的3-苄香豆素衍生物显示出对大麻素CB 1和CB 2受体的亲和力，并被确定为新的前导结构。在进一步的GTPγS结合研究中，选定的化合物显示为拮抗剂或反向激动剂。

  In the present study we synthesized 36 coumarin and 2H-chromene derivatives applying a recently developed umpoled domino reaction using substituted salicylaldehyde and α,β-unsaturated aldehyde derivatives as starting compounds. In radioligand binding studies 5-substituted 3-benzylcoumarin derivatives showed affinity to cannabinoid CB1 and CB2 receptors and were identified as new lead structures. In
