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 (K_i = 3.1 μM) and inhibits the binding of LTB₄ to its receptor on neutrophils (K_i = 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.

ChEBI: Cis-11,14-eicosadienoic acid methyl ester is a fatty acid methyl ester resulting from the formal condensation of the carboxy group of (11Z,14Z)-icosadienoic acid with methanol. It has a role as an animal metabolite. It is a fatty acid methyl ester and a polyunsaturated fatty ester. It is functionally related to an (11Z,14Z)-icosadienoic acid.
