In continuing our research with cytotoxic and pesticidal components from the stem bark of the North American paw paw, Asimina triloba, the novel cytotoxic monotetrahydrofuran Annonaceous acetogenins, cis- and trans-annonacin-A-one, cis- and trans-gigantetrocinone and cis-isoannonacin, in addition to the known compounds, trans-isoannonacin and squamolone, have been identified. Brine shrimp lethality testing was used to direct the fractionation. The structures were elucidated by spectral analysis and/or chemical synthesis. These acetogenins have potent cytotoxicities against the human tumour cell lines of A-549 (lung carcinoma), MCF-7 (breast carcinoma) and HT-29 (colon adenocarcinoma).
在继续对北美番荔枝（Asimina triloba）茎皮中的细胞毒性和杀虫成分进行研究时，除了已知化合物反式异番荔枝宁和鳞酮外，还鉴定出了新型细胞毒性单四氢呋喃番荔枝内酯、顺式和反式番荔枝acin - A - 酮、顺式和反式巨大菌素酮以及顺式异番荔枝acin。采用卤虫致死试验来指导分馏过程。通过光谱分析和/或化学合成确定了这些化合物的结构。这些番荔枝内酯对A - 549（肺癌）、MCF - 7（乳腺癌）和HT - 29（结肠腺癌）人肿瘤细胞系具有强大的细胞毒性。
