Two new quinoline alkaloids, aaptolines A and B, were isolated from the marine sponge Aaptos aaptos. Their structures were determined by HR-ESI-MS data, NMR analysis, and X-ray crystallography. Structurally, aaptoline A is characterized as having a quinoline skeleton fused with a 1,4-dioxane motif at the C(7)-C(8) position, whereas aaptoline B possessed an intriguing 1H-pyrrolo[2,3-g]quinoline moiety. The cytotoxic assay of these compounds showed no cytotoxicity towards HepG2, A549, and PC9 cancer cell lines and had IC values greater than 20 μm.
从海洋海绵 Aaptos aaptos 中分离得到两个新的喹啉生物碱,aaptolines A 和 B。通过高分辨电喷雾质谱(HR-ESI-MS)数据、NMR 分析和 X 射线晶体学确定了它们的结构。结构上,aaptoline A 的特征在于喹啉骨架在 C(7)-C(8) 位置与 1,4-二恶烷基融合,而 aaptoline B 则具有引人注目的 1H-吡咯并[2,3-g]喹啉部分。这些化合物的细胞毒性测定表明,它们对 HepG2、A549 和 PC9 癌细胞系没有细胞毒性,IC 值大于 20μm。
