bioassays to investigate their inhibitory activity against advanced glycation end products (AGEs). Among them, vinyl 4-hydroxycinnamate (17VP), vinyl 4-hydroxy-3-methoxycinnamate (18VP), vinyl 4-hydroxy-3,5-dimethoxycinnamate (20VP), ascorbyl 4-hydroxy-3-methoxycinnamate (18AP) and ascorbyl 3,4-dimethoxycinnamate (19AP) showed 2–10 times stronger inhibitory activities than positive control (aminoguanidine
这项研究成功地建立了化学合成两步法合成1-抗坏血酸酚酯的可行性。中间乙烯基酚首先化学方法生产的,然后例行反式与-esterification升中的Novozyme435®(存在抗坏血酸南极假丝酵母脂肪酶B)作为催化剂。对20种乙烯基酚盐和11种抗坏血酸酚盐进行了体外生物测定,以研究其对晚期糖基化终产物(AGEs)的抑制活性。其中,乙烯基-4-羟基肉桂酸酯(17VP),乙烯基4-羟基-3-甲氧基肉桂(18VP),乙烯基-4-羟基-3,5-酯二甲氧基(20VP),抗坏血酸4-羟基-3-甲氧基肉桂(18AP)和抗坏血酸3,4-酯二甲氧基(19AP)表现出比阳性对照(氨基胍和它的前体的2-10倍强的抑制活性)。这些结果表明化学合成的化合物具有AGE抑制作用,因此在预防或延迟糖基化蛋白质的形成方面是有效的。
