antiallergic activity in vitro. Ethanolamides of omega-3 fatty acids (α-linolenic acid, EPA, and DHA) were found to possess promising antiallergic activity, whereas free fatty acids and ethanolamides of other fatty acids exhibited no or weak potency. Based on this finding, structure–activity relationships of DHA-ethanolamide (DHEA) derivatives were investigated to yield better fatty acid derivatives with enhanced
探索了鱼油中的一系列不饱和脂肪酸及其相应的乙醇酰胺代谢物,以发现具有抗过敏活性的活性鱼油成分。发现ω-3脂肪酸的乙醇酰胺(α-亚麻酸,EPA和DHA)具有良好的抗过敏活性,而游离脂肪酸和其他脂肪酸的乙醇酰胺则没有或表现出弱的功效。基于这一发现,研究了DHA-乙醇酰胺(DHEA)衍生物的结构-活性关系,以在体内和体外产生具有增强的抗过敏活性的更好的脂肪酸衍生物。当DHEA的乙醇酰胺部分被取代的磺酰胺官能团取代时,在体外提供了非常有前途的效价。化合物59在体内显示出比DHEA更高的抗过敏活性。结果表明,优化的DHEA衍生物在体内和体外具有增强的抗过敏活性,并且所得结构将成为进一步开发具有良好抗过敏活性的生物利用性衍生物的重要基础。
