生物活性

製品説明 Tretazicar (CB1954) is a anticancer prodrug that is converted in the presence of the enzyme NQO2 and co-substrate caricotamide ( EP-0152R) (EP) into a potent cytotoxic bifunctional alkylating agent. It can be activated by NAD(P)H quinone oxidoreductase 2.
in vitro The overexpression of nitroreductase oxidored nitro domain containing protein 1 (NOR1) is capable of converting the monofunctional alkylating agent Tretazicar (CB1954) into a toxic form by reducing its 4-nitro group, resulting in a potent cytotoxin. This compound enhances cell killing in the NPC cell line CNE1. The NOR1 gene enhances CB1954-mediated cell cytotoxicity through the upregulation of Grb2 expression and the activation of MAPK signal transduction in the HepG2 cell line[1].
in vivo The NTR/Tretazicar (CB1954) system is used for specific ablation of cells in vivo. The effect of this inducible ablation system is dose-dependent[3]. NTR-mediated cell killing by this compound does not require cell proliferation. The activated form cross-links DNA which presumably triggers the apoptosis cascade, resulting in rapid cell death. Specific and effective cell killing by NTR-CB1954 does not require a functional p53[2].

実験の流れ

The human hepatocellular carcinoma cells, HepG2 are maintained in RPMI 1640 supplemented with 10% fetal calf serum (FCS) in a humidified culture incubator at 37˚C with 5% CO2 and 95% air. Cell cyto-toxicity assays are conducted as previously described. HepG2 cells grown to ~80% confluence are washed with PBS and treated with a signal transduction inhibitor and/or Tretazicar (CB1954). Measurements are collected from 10-12 individual microscopic fields in each experiment and data are summarized from 3-5 experiments.
