Two cyclic diarylheptanoids, acerogenins A (1) and B (2) have been isolated from the bark of Acernikoense as inhibitors of Na+-glucose cotransporter (SGLT). Acerogenins A (1) and B (2) inhibited both isoforms, SGLT1 and SGLT2. Structure–activity relationship of acerogenin derivatives on inhibitory activity of SGLT as well as conformational analysis of 1 and 2 on the basis of J-resolved HMBC spectra
We prepared a series of acerogenins A and B derivatives as inhibitors of nitric oxide (NO) production in vitro. Our results suggested that an ester group at a hydroxyl at C-2 improved inhibitory effects without cytotoxicity. A benzoyl ester derivative of acerogenin C showed the most potent inhibitory activity of NO production from lipopolysaccharide-activated macrophages.
我们制备了一系列金合欢苷 A 和 B 衍生物,作为体外一氧化氮(NO)产生的抑制剂。我们的研究结果表明,C-2羟基上的酯基提高了抑制效果,且无细胞毒性。芹菜甙元 C 的苯甲酰基酯类衍生物对脂多糖激活的巨噬细胞产生的一氧化氮具有最强的抑制活性。
