Four new acetylenic acids were isolated from the marine sponge Stelletta sp. by bioactivity-guided fractionation. The planar structures were established on the basis of NMR and MS analysis. The stereochemistry was defined by combined use of CD spectroscopy and a chiral anisotropic reagent, phenylglycine methyl ester (PGME). The compounds were evaluated for cytotoxicity against a small panel of five
从海洋海绵Stelletta sp。中分离出四种新的炔酸。通过生物活性指导的分馏。在NMR和MS分析的基础上建立了平面结构。立体化学是通过结合使用CD光谱和手性各向异性试剂苯基甘氨酸甲酯(PGME)来定义的。评估了该化合物对五种人类肿瘤细胞系的一小小组的细胞毒性,并显示了边缘至中度的细胞毒性。
