families of previously unrecognized saturated hydroxy fatty acids (SHFAs), namely, hydroxystearic and hydroxypalmitic acids, consisting of isomers with the hydroxyl group at different positions, were identified in milk. Among the various regio-isomers synthesized, those carrying the hydroxyl at the 7- and 9-positions presented growth inhibitory activities against various human cancer cell lines, including
生物活性脂质的领域不断扩大,发现了促进人类健康的新型脂质分子。通过脂质组学方法,在牛奶中鉴定了两个新的先前无法识别的饱和羟基脂肪酸(SHFA)家族,即羟基硬脂酸和羟基棕榈酸,它们由羟基位置不同的异构体组成。在合成的各种区域异构体中,那些在7和9位带有羟基的异构体表现出针对各种人类癌细胞系(包括A549,Caco-2和SF268细胞)的生长抑制活性。此外,7-和9-羟基硬脂酸能够抑制促炎性细胞因子诱导的β细胞凋亡,从而增加了它们在抵抗自身免疫性疾病(例如1型糖尿病)中的可能性。7-(R)-羟基硬脂酸在抑制细胞生长和抑制β细胞死亡方面均显示出最高的效力。我们建议,这种天然存在的SHFA可能在促进和保护人类健康中发挥作用。
