Four new indole alkaloids, melodinusines A-D (1, 2, 6, and 7), along with 26 known indole alkaloids, were isolated from Melodinus tenuicaudatus and Melodinus khasianus (Melodinus genus). Among them, 1 and 2 are aspidospermine-aspidospermine-type bisindole alkaloids while 7 is a novel melodinus-type alkaloid. Their structures were established on the basis of comprehensive spectroscopic data analysis and the structure of 7 was further confirmed by single-crystal X-ray diffraction analysis. Their cytotoxic activities against five human cancer cell lines, HL-60, SMMC-7721, A-549, MCF-7, and SW480 were also evaluated.
从密花轮环藤（Melodinus tenuicaudatus）和尼泊尔轮环藤（Melodinus khasianus）（密花轮环藤属）中分离得到了 4 个新的吲哚生物碱，即 melodinusines A-D（1、2、6 和 7），以及 26 个已知的吲哚生物碱。其中，1 和 2 为表阿朴-表阿朴长春胺型双吲哚生物碱，而 7 是一种新的密花轮环藤型生物碱。基于综合光谱数据分析确定了它们的结构，通过单晶 X 射线衍射分析进一步确定了 7 的结构。还评估了它们对五种人癌细胞系 HL-60、SMMC-7721、A-549、MCF-7 和 SW480 的细胞毒性活性。
