  探索第一个Rimonabant类似物-阿片肽杂合化合物，作为CB1和阿片受体的二价配体。

  摘要：

  大麻素（CB）和阿片类药物系统均与镇痛，食物摄入，情绪和行为有关。由于在中枢神经系统（CNS）的各个区域中，μ阿片类药物（MOR）和CB1受体共定位，并且它们具有形成异二聚体的能力，因此针对这两个系统的二价配体可能是研究是否存在阿片类药物的良好候选者。在次有效剂量下也可能产生串扰或协同效应。在这项工作中，我们从一小部分新的Rimonabant类似物中选择一种CB1R反向激动剂与阿片样物质Tyr-D-Ala-Gly-Phe-NH2偶联。二价化合物（9）已用于体外结合测定，体内抗伤害感受模型和体外下丘脑灌注试验，以评估神经递质的释放。

  Synthesis, Cannabinoid Receptor Affinity, and Molecular Modeling Studies of Substituted 1-Aryl-5-(1H-pyrrol-1-yl)-1H-pyrazole-3-carboxamides

  摘要：

  The new 1-phenyl-5-(1H-pyrrol-1-yl)pyrazole-3-carboxamides were compared with the reference compounds AM251 and SR144528 for cannabinoid hCB(1) and hCB(2) receptor affinity. Compounds bearing 2,4-dichlorophenyl or 2,4-difluorophenyl groups at position 1 and 2,5-dimethylpyrrole moiety at position 5 of the pyrazole nucleus were generally more selective for hCB(1). On the other hand, the N-cyclohexyl group at the 3-carboxamide was the determinant for the hCB2 selectivity, in particular when a 3,4-dichlorophenyl group was also present at position 1. Compound 26 was the most selective ligand for the hCB(1) receptor (K-i (CB2)/K-i (CB1) = 140.7). Derivative 30, the most potent hCB(1) ligand (Ki = 5.6 nM), was equipotent to AM251 and behaved as an inverse agonist in the cAMP assay (EC50 similar to 1 nM). The carbonyl oxygen of both 26 and 30 formed a H-bond with K3.28(192), while the substituents at the nitrogen fitted in a pocket formed by lipophilic residues. This H-bonding interaction was proposed to account for the high affinity for receptors' inactive state and the inverse agonist activity.

  New substituted 1-aryl-5-(1H-pyrrol-1-yl)-1H-pyrazole-3-carboxamides were synthesized by replacing the 2,4-dichlorobenzyl and cyclohexyl moieties at the 3-carboxamide nitrogen of the previously reported CB1 receptor antagonists/inverse agonists 4 and 5. Several ligands showed potent affinity for the hCB1 receptor, with Ki concentrations comparable to the reference compounds 1, 4 and 5, and exhibited

  A series of N-alkyl 1-ary1-5-(1H-pyrrol-1-yl)-1H-pyrazole-3-carboxamides were synthesized as new ligands of the human recombinant receptor hCB(1). n-Alkyl carboxamides brought out different SARs from the branched subgroup. Unsubstituted pyrrole derivatives bearing a tert-alkyl chain at the 3-carboxamide nitrogen showed greater hCB1 receptor affinity than the corresponding unbranched compounds. In particular, the tert-butyl group as a chain terminal moiety strongly improved hCB(1) receptor affinity (compound 24: K-i; = 45.6 nM; 29: K-i = 37.5 nM). Acute administration of either compound 12 or 29 resulted in a specific, dose-dependent reduction in food intake in rats. Such results provide an useful basis for the design of new CB1 ligands.
