chains, and targeting P-glycoprotein (P-gp) to minimize access to the brain. Compound 6a is a P-gp substrate and a potent and highly selective CB1R inverse agonist, demonstrating excellent in vivo metabolic stability and a low brain to plasma ratio. However, brain receptor occupancy studies showed that compound 6a may accumulate in brain with repeat dosing. This was evidenced by compound 6a inhibiting food
基于高通量筛选命中化合物1a,发现了一系列新的6-苯甲酰基-4-氨基-喹啉-2-酮类化合物作为大麻素1型受体(CB 1 R)反向激动剂。研究了结构与活性之间的关系,以改善体外/体内药理作用,并限制其向外周循环的分布。我们采用了几种策略,例如增加拓扑极性表面积,合并离散的聚乙二醇侧链以及靶向P-糖蛋白(P-gp),以最大程度地减少对大脑的访问。化合物6a是P-gp底物和有效且高度选择性的CB 1R反向激动剂,具有出色的体内代谢稳定性和较低的脑浆比。然而,脑受体占用研究表明,化合物6a可能在重复给药时在脑中积累。化合物6a抑制饮食诱导的肥胖小鼠的食物摄入并诱导其体重减轻可以证明这一点。因此,基于P-gp外排的策略可能不足以限制所公开的喹啉酮系列的外围。
