picomolar FAAH inhibitors (4c, IC50 = 0.3 ± 0.05 nM; 4d, IC50 = 0.8 ± 0.1 nM) were developed. Compound 4c inhibited FAAH in a rapid, selective, noncompetitive, and irreversible pattern. This study provides several highly potent and selective FAAH inhibitors and an optimized chemical scaffold for the development of FAAH inhibitors. We anticipate that these FAAH inhibitors will enable new possibilities in
脂肪酸酰胺水解酶(FAAH)是参与内源性大麻素(尤其是anandamide)生物降解的关键酶之一。FAAH的药理学阻断作用可恢复内源性大麻素的水平,从而在治疗炎症,抑郁和多发性硬化症方面提供治疗益处。在这项研究中,设计并合成了一系列尿嘧啶脲衍生物作为FAAH抑制剂。N-己基-2,4-二氧代-3,4-二氢嘧啶-1(2 H)-羧酰胺(1a的C5位置和侧链的结构修饰)导致FAAH抑制剂具有更高的效能和选择性。结构-活性关系(SAR)研究表明,C5吸电子取代基优选具有最佳效能,但不具有选择性,而用苯基烷基基团或联苯基取代烷基链可显着提高抑制效力和对FAAH的选择性。开发了两种高效的皮摩尔FAAH抑制剂(4c,IC 50 = 0.3±0.05 nM; 4d,IC 50 = 0.8±0.1 nM)。化合物4c以快速,选择性,非竞争性和不可逆的方式抑制FAAH。这项研究提供了几种高效和选择性的FAAH抑
