A series of new arctigenin and 9-deoxy-arctigenin derivatives bearing different ester and ether side chains at the phenolic hydroxyl positions are designed, synthesized, and evaluated for activating AMPK potency in L6 myoblasts. Initial biological evaluation indicates that some alkyl ester and phenethyl ether arctigenin derivatives display potential activities in AMPK phosphorylation improvement. Further
设计,合成并评估了一系列在酚羟基位置带有不同酯和醚侧链的新arctigenin和9-deoxy-arctigenin衍生物对L6成肌细胞激活AMPK的作用。初步的生物学评估表明,某些烷基酯和苯乙基artigeninin衍生物在AMPK磷酸化改善中显示出潜在的活性。进一步的结构-活性关系分析表明,arctigenin酯衍生物3a,3h和9-脱氧arctigenin苯醚衍生物6a,6c,6d激活AMPK的能力比arctigenin更高。此外,6c的2-(3,4-二甲氧基苯基)乙基部分已证明作为改善AMPK磷酸化作用的潜在官能团。Arctigenin的结构优化导致6c被鉴定为有前途的先导化合物,在AMPK激活中表现出出色的活性。
