(PDB-3W37) and oligo-1,6-glucosidase protein (PDB-3AJ7). Five catalpol iridoids (1, 2, 10, 13, 14) were isolated from mangrove plant D. spathacea, and their derivatives (3, 4, 5, 6, 7, 8, 9, 11, 12, 15) were obtained from reduction, acetylation, O-alkylation, acetonisation, or hydrolysation starting from naturally isolated compounds. They were identified by spectral methods such as IR, MS, and 1D and 2D NMR
Dolichandrone spathacea iridoids 是一种很有前景的 α-葡萄糖苷酶蛋白 (PDB-3W37) 和寡聚 1,6-葡萄糖苷酶蛋白 (PDB-3AJ7) 抗糖尿病抑制剂。从红树植物D. spathacea中分离得到5个梓醇环烯醚萜类化合物(1 , 2 , 10 , 13 , 14) ,并从红树林植物D. spathacea中分离得到其衍生物( 3 , 4 , 5 , 6 , 7 , 8 , 9 , 11 , 12 , 15 )。从天然分离的化合物开始进行还原、乙酰化、 O-烷基化、丙酮化或水解。它们通过红外、质谱、一维和二维核磁共振等光谱方法进行鉴定。通过分子对接模拟预测它们的葡萄糖苷酶相关(3W37和3AJ7)抑制性和生理相容性,并根据Lipinski五法则进行预筛选。使用酶测定法评估1-15的实验性 α-葡萄糖苷酶抑制。化合物3、4、5、6和9是新的环烯醚萜衍
