Chemical profiles of and were investigated, resulting in the isolation of five new discorhabdin D derivatives and -. Their planar structures were solved by combination of NMR and HR-MS, while -based configurational analysis, computational techniques, and semisynthetic methods were used for the establishment of their absolute configurations. New natural products were tested for their growth inhibitory activity against the NCI-60 human tumor cell line panel, and two compounds and showed low micromolar potency.
对 和 进行了化学成分研究,分离得到了五个新的 discorhabdin D 衍生物 和 -。通过 NMR 和 HR-MS 的组合确定了它们的平面结构,而 - 的构型分析、计算技术和半合成方法则用于确定它们的绝对构型。对新的天然产物进行了对 NCI-60 人肿瘤细胞系的生长抑制活性测试,两种化合物 和 表现出低微摩尔活性。
