9 nitrooleate

Nitrated unsaturated fatty acids, such as 10- and 12-nitrolinoleate , cholesteryl nitrolinoleate, and nitrohydroxylinoleate, represent a new class of endogenous lipid-derived signalling molecules. LNO2 isomers serve as potent endogenous ligands for PPARγ and can also decompose or be metabolized to release nitric oxide. 9-Nitrooleate is one of two regioisomers of nitrooleate, the other being 10-nitrooleate (OA-NO2; used for the mixture of isomers), which are formed by nitration of oleic acid in approximately equal proportions in vivo. Peroxynitrite, acidified nitrite, and myeloperoxidase in the presence of H2O2 and nitrite, all mediate the nitration of oleic acid. OA-NO2 is found in human plasma as the free acid and esterified in phospholipids at concentrations of 619 ± 52 nM and 302 ± 369 nM, respectively. OA-NO2 activates PPARγ approximately 7-fold at a concentration of 1 μM and effectively promotes differentiation 3T3-L1 preadipocytes to adipocytes at 3 μM.

9(10)-Nitrooleate，一个内源性脂质信号分子混合体，主要由9-硝基油酸和10-硝基油酸组成。在过氧亚硝酸、酸化亚硝酸和髓过氧化物酶的作用下，该化合物通过与过氧化氢（H2O2）和亚硝酸反应，硝化油酸而形成。

10-Nitrooleate是一种高纯度生化试剂，适合作为生物材料或有机合成中间体，广泛应用于生命科学领域的研究与实验。
