Abstract

Cannabinoid type 2 receptor (CB2R), belonging to the endocannabinoid system, is overexpressed in pathologies characterized by inflammation, and its activation counteracts inflammatory states. Fatty acid amide hydrolase (FAAH) is an enzyme responsible for the degradation of the main endocannabinoid anandamide; thus, the simultaneous CB2R activation and FAAH inhibition may be a synergistic anti-inflammatory strategy. Encouraged by principal component analysis (PCA) data identifying a wide chemical space shared by CB2R and FAAH ligands, we designed a small library of adamantyl-benzamides, as potential dual agents, CB2R agonists, and FAAH inhibitors. The new compounds were tested for their CB2R affinity/selectivity and CB2R and FAAH activity. Derivatives , , and , displaying the best pharmacodynamic profile as CB2R full agonists and FAAH inhibitors, decreased pro-inflammatory and increased anti-inflammatory cytokines production. Molecular docking simulations complemented the experimental findings by providing a molecular rationale behind the observed activities. These multitarget ligands constitute promising anti-inflammatory agents.

摘要

2型大麻素受体(CB2R)属于内源性大麻素系统,在以炎症为特征的病理状态中过度表达,其激活可对抗炎症状态。脂肪酸酰胺水解酶(FAAH)是一种负责降解主要内源性大麻素花生四烯乙醇胺的酶;因此,同时激活CB2R和抑制FAAH可能是一种协同抗炎策略。受主成分分析(PCA)数据的鼓舞,这些数据确定了CB2R和FAAH配体共享的广阔化学空间,我们设计了一个金刚烷基苯甲酰胺小文库,作为潜在的双重作用剂、CB2R激动剂和FAAH抑制剂。对新化合物进行了CB2R亲和力/选择性以及CB2R和FAAH活性测试。作为CB2R完全激动剂和FAAH抑制剂表现出最佳药效学特征的衍生物、和,减少了促炎细胞因子的产生并增加了抗炎细胞因子的产生。分子对接模拟通过提供观察到的活性背后的分子原理补充了实验结果。这些多靶点配体构成了有前景的抗炎剂。
