discovery of the oxazolidone derivative as a novel scaffold for NAAA inhibitors, and studied the structure–activity relationship (SAR) by modification of the side chain and terminal lipophilic substituents. The results showed that the link chain length of C5, straight and saturated linkages were the preferred shape patterns for NAAA inhibition. Several nanomolar NAAA inhibitors were described, including
N-乙酰乙醇胺水解酸酰胺酶(NAAA)是一种溶酶体酶,可催化内源性脂肪酸乙醇酰胺(FAE)(例如N-棕榈酰乙醇酰胺(PEA)。PEA通过与过氧化物酶体增殖物激活的受体α(PPAR-α)结合表现出抗炎和镇痛作用。已经提出通过抑制NAAA来防止PEA降解是治疗炎症和疼痛的新策略。在本研究中,我们报道了恶唑烷酮衍生物作为NAAA抑制剂的新型支架的发现,并通过修饰侧链和末端亲脂性取代基研究了结构-活性关系(SAR)。结果表明,C5的链长,直链和饱和键是抑制NAAA的优选形状。描述了几种纳摩尔NAAA抑制剂,包括2f,3h,3i和3jIC 50值分别为270 nM,150 nM,100 nM和190 nM。酶促降解研究表明2f以选择性,非竞争性和可逆的方式抑制NAAA。此外,在全身和口服给药后,2f表现出很高的抗炎和镇痛活性。
