    • Five new nucleophile substituted ecteinascidin (Et) compounds have been isolated from extracts of Ecteinascidia turbinata. These compounds have been purified by chromatographic techniques and their structures and bioactivities have been determined. The five nucleophile substituted Et compounds have been designated herein as Et 802 (1), Et 788 (2), Et 760 (3), Et 858 (4) and Et (815) (5). Also obtained were three new N-oxide ecteinascidin compounds, which have been designated herein as Et 717 (6), Et 775 (7) and Et 789 (8). Some of these newly discovered Et compounds show exceedingly potent cytotoxicity against L1210.
    • 五种新的亲核取代的ecteinascidin(Et)化合物已从Ecteinascidia turbinata的提取物中分离出来。 这些化合物已经通过色谱技术纯化,并且已经确定了它们的结构和生物活性。 本文将五种亲核取代的Et化合物称为Et 802(1),Et 788(2),Et 760(3),Et 858(4)和Et(815)(5)。 还获得了三种新的N-氧化物角叉菜胶化合物,其在本文中被称为Et 717(6),Et 775(7)和Et 789(8)。 这些新发现的Et化合物中的一些对L1210显示出极强的细胞毒性。
