化合物K是三七总皂苷的活性代谢产物之一,可通过激活LXRα抑制小鼠动脉粥样硬化的形成。本文合成了一系列短链脂肪酸修饰的含氮化合物K衍生物,并对其进行了评价。该类化合物K衍生物的所有结构均表现出与化合物K相当或更好的生物活性。尤其是结构1表现出最好的功效(胆固醇酯含量:41.51%; ABCA 1 mRNA表达:319%)和低细胞毒性。
Compound K is one of the active metabolites of Panaxnotoginseng saponins, which could attenuate the formation of atherosclerosis in mice modelsvia activating LXRα. We synthesized and evaluated a series of ginsenoside compound K derivatives modified with short chain fatty acids. All of the structures of this class of ginsenoside compound K derivative exhibited comparable or better biological activity than ginsenoside compound K. Especially structure 1 exhibited the best potency (cholesteryl ester content: 41.51%; expression of ABCA1 mRNA: 319%) and low cytotoxicity.
