γlinolenic acid ethyl ester

γ-Linolenic acid ethyl ester (Ethyl γ-linolenate) is a leukotriene B4 receptor 4 (LTB4) antagonist with potential anti-inflammatory effects[1].

Ethyl dihomo-γ-linolenic acid ethyl ester (ethyl DGLA), an ω-6 fatty acid intermediate ester form, elevates prostaglandin E1(PGE1) and PGE2 secretion in rabbit renal papilla when administered dietarily at a dosage of 1 g/kg per day for 25 days. Additionally, this dosage of ethyl DGLA increases triglyceride levels and enhances the proportion of 20:3ω6 and 20:4ω6 phospholipids in the renal medulla of rabbits. Ethyl DGLA formulations have been employed in managing eczema and inflammatory disorders.

Ethyl linolenate is a fatty acid ethyl ester that exhibits anti-melanogenic properties by suppressing cellular melanin synthesis with an IC50 of 70 μM.Ethyl linolenate inhibit forskolin-stimulated melanogenesis and reduces tyrosinase enzymatic activity. Its antimelanogenic profile supports the utilization of Ethyl linolenate in pigmentation disorder research and skin-lightening mechanism studies.
