内源性大麻素(eCB)信号传导的药物增强是一种新兴的治疗方法,用于治疗广泛的病理生理学病症。迄今为止,药理学方法主要集中在抑制经典的 eCB 失活途径、anandamide 的脂肪酸酰胺水解酶和 2-花生四烯酰甘油的单酰基甘油脂肪酶。在这里,我们回顾了环氧合酶 2 介导的 eCB 氧合代表了终止 eCB 对大麻素受体作用的第三种机制的实验证据。我们描述了“底物选择性”COX-2 抑制剂的开发、分子机制和体内验证,该抑制剂可防止 COX-2 使 eCB 失活,而不影响花生四烯酸产生前列腺素。最后,我们回顾了底物选择性 COX-2 抑制剂潜在治疗应用的最新数据,重点关注神经精神疾病。
Pharmacologic augmentation of endogenous cannabinoid (eCB) signaling is an emerging therapeutic approach for the treatment of a broad range of pathophysiological conditions. Thus far, pharmacological approaches have focused on inhibition of canonical eCB inactivation pathways, fatty acid amide hydrolase for anandamide and monoacylglycerol lipase for 2-arachidonoylglycerol. Here we review experimental evidence that cyclooxygenase-2-mediated eCB oxygenation represents a third mechanism for terminating eCB action at cannabinoid receptors. We describe the development, molecular mechanisms, and in vivo validation of “substrate-selective” COX-2 inhibitors that prevent eCB inactivation by COX-2 without affecting the prostaglandin generation from arachidonic acid. Lastly, we review recent data on the potential therapeutic applications of substrate-selective COX-2 inhibitors with a focus on neuropsychiatric disorders.
