to mice improves glucose homeostasis and increases energy expenditure, indicating that this pathway might be useful for treating obesity and associated disorders. We report the full account of the synthesis and mitochondrial uncoupling bioactivity of lipidated N-acyl amino acids and their unnatural analogues. Unsaturated fatty acid chains of medium length and neutral amino acid head groups are required
N-酰基氨基酸直接结合线粒体并充当不依赖于 UCP1 的呼吸的内源解偶联剂。我们发现给小鼠施用N-酰基氨基酸可以改善葡萄糖稳态并增加能量消耗,表明该途径可能有助于治疗肥胖和相关疾病。我们报告了脂化N-酰基氨基酸及其非天然类似物的合成和线粒体解偶联生物活性的完整说明。中等长度的不饱和脂肪酸链和中性氨基酸头基是哺乳动物细胞上最佳解偶联活性所必需的。一类非天然N-酰基氨基酸类似物,其特征为异吲哚啉-1-羧酸酯头基(37),能够抵抗 PM20D1 的酶促降解,并在细胞和小鼠体内保持解偶联生物活性。
