A new tetracyclic bis-piperidine alkaloid, neopetrosiamine A (1), has been extracted from the marine sponge Neopetrosiaproxima collected off the west coast of Puerto Rico. The structure of compound 1 was elucidated by analysis of spectroscopic data coupled with careful comparisons of its (1)H and (13)C NMR data with those of a well-known 3-alkylbis-piperidine alkaloid model. The new alkaloid displayed strong in vitro cytotoxic activity against a panel of cancer cell lines as well as in vitro inhibitory activity against the pathogenic microbes Mycobacterium tuberculosis and Plasmodium falciparum.
一种新的四环双哌啶生物碱,新海绵胺 A(1),已从波多黎各西海岸采集的海洋海绵 Neopetrosiaproxima 中提取出来。通过分析光谱数据并仔细比较其 1H 和 13C NMR 数据与已知的 3-烷基双哌啶生物碱模型的 1H 和 13C NMR 数据,确定了化合物 1 的结构。新的生物碱对一系列癌细胞系具有很强的体外细胞毒性活性,并且对致病微生物结核分枝杆菌和疟原虫具有体外抑制活性。
