docosahexaenoic acid methyl ester

Docosahexaenoic Acid methyl ester (all cis-DHA methyl ester) 是甲基化的二十二碳六烯酸类似物，能够插入膜磷脂中而不被氧化或水解。

Resolvin D1 is produced physiologically from the sequential oxygenation of docosahexaenoic acid by 15- and 5-lipoxygenase . It reduces human polymorphonuclear leukocyte transendothelial migration, the earliest event in acute inflammation, with an EC50 value of ~30 nM. RvD1 methyl ester is a methyl ester version of the free acid that may act as a lipophilic prodrug form that will alter its distribution and pharmacokinetic properties. The methyl ester moiety is susceptible to cleavage by intracellular esterases, leaving the free acid.

Resolvin D2 (RvD2) is a lipid mediator biosynthesized by the sequential oxygenation of docosahexaenoic acid by 15- and 5-lipoxygenase. It evokes diverse anti-inflammatory effects which may mediate the resolution of inflammation. RvD2 methyl ester is a methyl ester version of the free acid which may act as a lipophilic prodrug form that will alter its distribution and pharmacokinetic properties. The methyl ester moiety is susceptible to cleavage by intracellular esterases, leaving the free acid.

Resolvin D5是一种从DHA中提取的氧化脂质介质，具有抗炎作用，在LPS刺激的THP-1细胞中通过ERK-NF-κB信号通路抑制IL-6和CCL5的产生。

Heneicosapentaenoic Acid (HPA) is a fatty acid found in small amounts in Bryopsis pennata Lamouroux green algae and fish oils, with a structure similar to eicosapentaenoic acid (EPA), but with an additional carbon at the carboxyl end, resulting in the first double bond being in the Δ6 position. HPA is important for researching the impact of double bond positions in n-3 fatty acids, as it integrates into phospholipids and triacylglycerol in vivo as effectively as EPA and docosahexaenoic acid (DHA), while strongly inhibiting the synthesis of arachidonic acid from linoleic acid. Despite being a poor substrate for prostaglandin H (PGH) synthase and 5-lipoxygenase, HPA can rapidly deactivate PGH synthase. HPA methyl ester, in certain formulations, acts as a prodrug to enhance cellular uptake of HPA before being converted into free acid by esterases, and serves as a useful reference standard.

omega-3 Arachidonic Acid methyl ester 主要包括二十二碳六烯酸、二十碳五烯酸和 α-亚油酸，是正常生长发育所需的必需膳食营养素。omega-3 Arachidonic Acid methyl ester 是一种中性脂溶性的稀有脂肪酸，属于ω-3花生四烯酸。作为一个组，ω-3脂肪酸与炎症及自身免疫活动的降低有关，同时也减少血栓形成和血小板活化。
