Bioassay-guided separation of an extract of the wings from a Taiwan butterfly, Byasa polyeuctes termessa, allowed isolation of a new cancer cell growth inhibitor designated papilistatin (1a). The structure was determined by analysis of 1D and 2D NMR spectra and by HRMS. Against a panel of six human and the murine P388 leukemia cancer cell lines, papilistatin exhibited cancer cell growth inhibition with GI(50)'s of 0.093-3.5 microg/mL. Papilistatin was also found to have antibacterial activity.
生物测定指导下分离台湾凤蝶翅膀提取物,得到一种新型的癌细胞生长抑制剂,命名为帕皮利斯坦(1a)。其结构通过 1D 和 2D NMR 谱分析和高分辨质谱确定。对六种人源和鼠源 P388 白血病癌细胞系进行活性测试,帕皮利斯坦对癌细胞生长的半数抑制浓度(GI50)为 0.093-3.5 微克/毫升。此外,帕皮利斯坦还具有抗菌活性。
