inflammation and pain. Thus, blocking the degradation of PEA with NAAA inhibitors results in augmentation of the PEA/PPAR-α signaling pathway and regulation of inflammatory and pain processes. We have prepared a new series of NAAA inhibitors exploring the azetidine-nitrile (cyanamide) pharmacophore that led to the discovery of highly potent and selective compounds. Key analogs demonstrated single-digit nanomolar
N-酰基乙醇胺酸酰胺酶(NAAA)抑制代表了一种激动人心的新颖方法,用于治疗炎症和疼痛。NAAA是半胱氨酸酰胺酶,可优先水解内源性生物脂质棕榈酰乙醇酰胺(PEA)和油酰乙醇酰胺(OEA)。PEA是核过氧化物酶体增殖物激活受体-α(PPAR-α)的内源性激动剂,PPAR-α是炎症和疼痛的关键调节剂。因此,用NAAA抑制剂阻止PEA的降解会导致PEA /PPAR-α信号传导途径的增强以及炎症和疼痛过程的调节。我们准备了一系列新的NAAA抑制剂,用于研究氮杂环丁烷-腈(氰胺)药效团,从而发现了高效且选择性强的化合物。关键类似物显示出hNAAA的一位数纳摩尔效价,并显示> 对丝氨酸水解酶FAAH,MGL和ABHD6和半胱氨酸蛋白酶组织蛋白酶K的选择性是100倍。此外,我们已经确定了有效的和选择性的双重NAAA-FAAH抑制剂来研究两种不同的抗炎分子途径PEA / PPAR之间的潜在协同作用-α抗炎
