nitro-fatty acids, acting as partial agonist of PPARγ, are able to lower the insulin and glucose levels without the side effects associated with common antidiabetic drugs. (E)-12-Nitrooctadec-12-enoic acid, a potent activator of this peroxisome receptor, was synthesized in a very efficient sequence via a Henry−retro-Claisen ring fragmentation, followed by a novel enzymatic cleavage of methyl esters. The latter
内源性硝基脂肪酸作为PPARγ的部分激动剂,能够降低胰岛素和葡萄糖水平,而没有常见抗糖尿病药的副作用。(E)-12-硝基十八烷基-12-烯酸,一种过氧化物酶体受体的有效活化剂,是通过亨利-复古-克莱森环断裂,然后通过新的甲酯酶解以非常有效的顺序合成的。然后将后一种方法应用于一些不稳定的天然产物(如前列腺素,异前列腺素和植物前列腺素)的合成的最后一步。
