5(z),11(z),14(z)eicosatrienoic acid

5(Z),11(Z),14(Z)-Eicosatrienoic acid is a polyunsaturated fatty acid found in various natural sources including maritime pine (Pinus pinaster) seed oil (MPSO), gymnospermae leaves and seeds, and freshwater gastropods. A diet containing MPSO lowered high-density lipoprotein and ApoA1 levels in transgenic mice expressing human ApoA1. MPSO was found to diminish cholesterol efflux in vitro. 5(Z),11(Z),14(Z)-Eicosatrienoic acid methyl ester, when topically applied, reduces inflammatory processes, potentially by displacing arachidonic acid from phospholipid pools and reducing downstream inflammatory products such as prostaglandin E2 and leukotrienes.

5(Z),8(Z),14(Z)-Eicosatrienoic acid is a polyunsaturated fatty acid that can be a substrate for 5-lipoxygenase (5-LO). 5-LO from RBL-1 cells converts this fatty acid to 5-hydroxy-6,8,14-eicosatrienoic acid and 5-hydroperoxy-6,8,14-eicosatrienoic acid. Due to the lack of a double bond at C-11, this particular fatty acid cannot be used in leukotriene A formation.

11(Z),14(Z)-Eicosadienoic acid methyl ester is a more lipid soluble form of the ω-6 C20-2 fatty acid 11(Z),14(Z)-eicosadienoic acid , a naturally occurring PUFA. 11(Z),14(Z)-Eicosadienoic acid competitively inhibits inosine 5'-monophosphate dehydrogenase (Ki = 3.1 μM) and inhibits the binding of LTB4 to its receptor on neutrophils (Ki = 3.0 μM). Also, serum levels of eicosadienoic acids negatively correlate with degree of sleep disturbance. Eicosadienoic acids are converted by desaturases, in vivo, to eicosatrienoic acids, which are potent vasodilators.

8(S),9(R)-EET是由细胞色素P450从花生四烯酸 (AA) 转化得到的二十烷酸产物。此化合物能以浓度依赖的方式扩张犬心外膜小动脉，其EC50为121 nM。

8(R),9(S)-EET，一种Epoxyeicosatrienoic acid的异构体，通过胞质环氧水解酶 (CEH) 的催化作用生成，其亲和力Km值为41μM。
