(2) and (S)-N-(2-oxo-3-oxetanyl)-biphenyl-4-carboxamide (3) inhibit NAAA, prevent FAE hydrolysis in activated inflammatory cells, and reduce tissue reactions to pro-inflammatory stimuli. Recently, our group disclosed ARN077 (4), a potent NAAA inhibitor that is active in vivo by topical administration in rodent models of hyperalgesia and allodynia. In the present study, we investigated the structure–activity
N-乙酰乙醇胺酸酰胺酶(NAAA)是一种溶酶体半胱氨酸水解酶,参与了过氧化物酶体增殖物激活受体-α的内源性脂质激动剂家族的饱和和单不饱和脂肪酸乙醇酰胺(FAE)的降解,其中包括油酰基乙醇酰胺(OEA)和棕榈酰乙醇酰胺(PEA)。β-内酯衍生物(S)-N-(2-氧代-3-氧杂环丁烷基)-3-苯基丙酰胺(2)和(S)-N-(2-氧代-3-氧杂环丁烷基)-联苯-4-羧酰胺(3)抑制NAAA,防止FAE在活化的炎性细胞中水解,并减少组织对促炎性刺激的反应。最近,我们小组披露了ARN077(4),一种有效的NAAA抑制剂,在痛觉过敏和异常性疼痛的啮齿动物模型中通过局部给药在体内具有活性。在本研究中,我们研究了苏氨酸衍生的化合物4的β-内酯类似物的结构-活性关系(SAR)。这项工作的主要结果是增强了β-内酯氨基甲酸酯衍生物对NAAA的抑制能力,并鉴定了(4-苯基苯基)-甲基-N -[(2 S,3 R)-2-甲基-4-
