Biological Information

  • Product Name
    Ecteinascidin 770
  • Note
    Research use only, not for human use.
  • Brief Description
    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.
  • Description
    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.
  • In Vitro
    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.
