kinetic analysis suggested that oxazolidone derivatives with different terminal phenyl moieties inhibited NAAA via different mechanisms. This study identified several highly potent NAAA inhibitors, including 1a (F215, IC50 = 0.009 μM), 1o (IC50 = 0.061 μM) and 2e (IC50 = 0.092 μM), and also determined structural requirements of oxazolidone derivatives for potent inhibition against NAAA.
ñ-酰基乙醇胺酸酰胺酶(NAAA)是半胱氨酸水解酶,参与脂肪酸乙醇酰胺(如棕榈酰乙醇酰胺(PEA))的失活。NAAA抑制可为治疗需要更高PEA水平的疾病提供潜在的治疗策略。在本研究中,我们报道了恶唑烷酮衍生物作为NAAA抑制剂的结构-活性关系(SAR)研究。研究了恶唑烷酮衍生物的末端苯环的一系列取代基或烷基取代基。结果表明,这些恶唑烷酮衍生物对NAAA的抑制能力取决于末端基团的大小,柔韧性和亲脂性。SAR结果表明,较小的亲脂性3-苯基取代基或含羟基的4-苯基取代基对于获得最佳效价是优选的。此外,出于高抑制效力,也优选远端脂肪族替代物。快速稀释和动力学分析表明,具有不同末端苯基部分的恶唑烷酮衍生物通过不同的机理抑制NAAA。这项研究确定了几种高效的NAAA抑制剂,包括1a(F215,IC 50 = 0.009μM ),1o(IC 50 = 0.061μM)和2e(IC 50 = 0.0
