Logeracemin A (1), the first Daphniphyllum alkaloid dimer featuring an unprecedented carbon skeleton with a unique conjugated trispiro[4,5] decane backbone, was isolated from Daphniphyllum longeracemosum. Its structure and absolute configuration were established on the basis of spectroscopic data and X-ray crystallography. Logeracemin A showed significant anti-HIV activity with an EC50 of 4.5 ± 0.1 μM and a selectivity index of 6.2. The structure-activity relationship of the tested compounds was briefly discussed.
洛革拉敏 A（1），是首次从长叶木莲中分离得到的具有独特共轭三螺[4,5]癸烷骨架的罕见碳骨架的重楼生物碱二聚体，其结构和绝对构型是基于光谱数据和 X 射线晶体学确定的。洛革拉敏 A 表现出显著的抗 HIV 活性，EC50 为 4.5±0.1 μM，选择性指数为 6.2。简要讨论了测试化合物的构效关系。
