A series of sugar derivatives (7-14) were synthesized from stachyose, a sugar compound of Stachys sieboldi Miq, and evaluated for antibacterial activity against Mycobacterium tuberculosis, Mycobacterium avium, and Staphylococcus aureus, and their structure-activity relationships were studied. The results showed that the compound OCT359 (allyl O-(2,3,4,6-tetra-O-acetyl-alpha-D-galactopyranosyl)-(1-->6)-O-(2
从水苏糖中提取了一系列的糖衍生物(7-14),水苏糖为水苏木的糖化合物,并评估了其对结核分枝杆菌,鸟分枝杆菌和金黄色葡萄球菌的抗菌活性,并研究了它们的结构-活性关系。结果显示化合物OCT359(烯丙基O-(2,3,4,6-四-O-乙酰基-α-D-吡喃半乳糖基)-(1-> 6)-O-(2,3,4-三-O-乙酰基-α-D-吡喃半乳糖基)-(1-> 6)-O-2,3,4-三-O-乙酰基-β-D-吡喃葡萄糖苷)(12)表现出体外抗菌活性。C-1处的烯丙基和甘露糖苷的乙酰氧基是抗菌活性所必需的。
