具有有效抗癌活性的四氢异喹啉生物碱；显示对人细胞系 HCT116、QG56 和 DU145 的细胞毒性，IC50 分别为 0.60、2.4 和 0.81 nM。

A tetrahydroisoquinoline alkaloid with potent anticaner activities; shows cytotoxicity against human cell lines HCT116, QG56, and DU145 with IC50 of 0.60, 2.4, and 0.81 nM, respectively; sensitizes H23 the cells by activating the p53 protein, down-regulates MCL1 and up-regulates BAX proteins, with no effect on Bcl-2; enhances anoikis response of human lung cancer H23 and H460 cells.

Ecteinascidin 770 induces apoptosis of U373MG cells. The IC50 concentration of ecteinascidin 770 for killing U373MG glioblastoma cells in culture by using the MTT assay is 4.83 nM by a 72 hour-treatment. The IC50 values against human cell lines HCT116, QG56, and DU145 are 0.6, 2.4, and 0.81 nM, respectively. ET-770 is shown to enhance anoikis response of human lung cancer H23 cells in a dose-dependent manner. Ecteinascidin 770 sensitizes the cells by activating the p53 protein, which in turn down-regulates anti-apoptotic myeloid cell leukemia sequence-1 (MCL1) and up-regulates BCL2-associated X protein (BAX) proteins. However, B-cell lymphoma-2 (BCL2) proteins are not significantly affected by Ecteinascidin 770. The anoikis sensitization of ET-770 is observed in H460 lung cancer cells.
