Sixteen tyrosol derivatives were synthesized and characterized by NMR and HR-MS. The antioxidant activity of those compounds was evaluated using four different assays. The results showed that some target compounds displayed better antioxidant activity than L-ascorbic acid and Trolox. Five target compounds exhibited more potent α-glucosidase inhibition activity (18.1–56.7 μM) than acarbose (60.9 μM). Eight target compounds showed some anticholinesterase activities.
合成并表征了十六种酪醇衍生物,采用NMR和高分辨质谱(HR-MS)进行检测。这些化合物的抗氧化活性通过四种不同的测定方法进行评估。结果表明,一些靶向化合物的抗氧化活性优于L-抗坏血酸和Trolox。五种靶向化合物展现出比阿卡波糖更强的α-葡萄糖苷酶抑制活性(18.1–56.7 μM),而阿卡波糖的活性为60.9 μM。有八种靶向化合物显示出一定的抗胆碱酯酶活性。
