摘要
Five new nucleophile substituted ecteinascidin compounds were isolated from extracts of Exteinascidia turbinata and designated Et 802, Et 788, Et 760, Et 858 and Et 815. Three new N-oxides were also obtained and designated Et 717, Et 775 and Et 789. Some of these newly discovered Et compounds show exceedingly potent cytotoxicity against L1210.
