High-throughput natural products chemistry methods have led to the isolation of three new (1-3) and two known indole sesquiterpene alkaloids (4, 5) from Greenwayodendron suaveolens. Their structures were determined using CapNMR and MS. Pentacyclindole (1) was determined to possess a new natural product framework. Pentacyclindole (1) and polyalthenol (4) showed activity against clinical isolates of Staphylococcus aureus with polyalthenol (4) demonstrating a MIC(90) of 4 microg/mL.
高通量天然产物化学方法已从绿楠中分离得到三种新的（1-3）和两种已知的吲哚倍半萜生物碱（4,5）。它们的结构通过 CapNMR 和 MS 确定。戊环吲哚（1）被确定具有新的天然产物骨架。戊环吲哚（1）和多醇（4）对金黄色葡萄球菌的临床分离株表现出活性，其中多醇（4）的 MIC（90）为 4 μg/mL。
