able to inhibit the FAAH activity in rat basophilic leukemia cells as assessed by measuring either the hydrolysis of anandamide, the FAAH-dependent cellular accumulation of anandamide, or the FAAH-dependent recycling of tritium to the cell membranes. The compound also inhibited the activity of monoacylglycerol lipase (MGL), the enzyme responsible for the hydrolysis of the endogenous cannabinoid receptor
脂肪酸酰胺水解酶(FAAH)是内源性大麻素受体配体anandamide的关键水解酶。描述了一系列18种对乙酰氨基酚酯的FAAH抑制活性的合成和评估。构效关系研究表明,具有2-(4-(2-(三氟甲基)吡啶-4-基氨基)苯基)乙酸取代基的酯(33)是该系列中最有效的类似物。该化合物与K i以竞争性方式抑制FAAH活性。值为0.16μM。该化合物还能够抑制大鼠嗜碱性白血病细胞中的FAAH活性,方法是通过测量anandamide的水解,依赖于FAAH的anandamide的细胞蓄积或依赖于FAAH的recycling向细胞膜的再循环来评估。该化合物还抑制了单酰基甘油脂肪酶(MGL)的活性,该酶负责内源性大麻素受体配体2-花生四烯酸甘油的水解,IC 50值为1.9μM。结论是该化合物可能是设计有效的FAAH新型抑制剂的有用模板。
