γ-Linolenic Acid methyl ester
(Synonyms: r-亚麻酸甲酯,Methyl GLA,Methyl γ-Linolenate) 目录号 : GC10020A dietary ω-6 PUFA
Cas No.:16326-32-2
Sample solution is provided at 25 µL, 10mM.
γ-Linolenic Acid methyl ester is a weak leukotriene B4 (LTB4) receptor antagonist.
LTB 4, a potent neutrophil chemoattractant, is present at high concentrations in psoriatic lesions, bronchoalveolar lavage in asthmatics and rectal dialysates in patients with inflammatory bowel disease.
In vitro: γ-Linolenic acid methyl ester is an esterified version of the free acid which is less water soluble but more amenable for the formulation of GLA-containing diets and dietary supplements. GLA was identified as an ω-6 fatty acid which could be elongated to arachidonic acid for endogenous eicosanoid synthesis. GLA was found to be a weak leukotriene B4 (LTB4) receptor antagonist, which was able to inhibit [3H]-LTB4 binding to porcine neutrophil membranes with a Ki of 1 μM [1].
In vivo: In an in-vivo model of LTB4-induced bronchoconstriction, ricinelaidic acid andγ-Linolenic acid methyl ester at a 1 mg/kg i.v. dose could result in 46% and 53% inhibition, respectively, indicating that essential fatty acids are LTB4 receptor antagonists, which may account in part for their reported anti-inflammatory activities [1].
Clinical trial: So far, no clinical study has been conducted.
