体内（毎回新しく調製した物を用意してください）

Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	2.500mg/ml (9.91mM)	Taking the 1 mL working solution as an example, add 50 μL of 50 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	5% DMSO 1 95% Corn oil この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	0.410mg/ml (1.63mM)	Taking the 1 mL working solution as an example, add 50 μL of 8.2 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	Tretazicar（CB1954）は、NQO2酵素と補基質caricotamide（EP-0152R）（EP）の存在下で、強力な細胞毒性二官能性アルキル化剤に変換される抗がんプロドラッグです。これはNAD(P)Hキノン酸化還元酵素2によって活性化され得ます。
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, which is 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.
in vivo	The Tretazicar (CB1954) system is used for specific ablation of cells in vivo. The effect of this inducible ablation system is dose-dependent. 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.

プロトコル(参考用のみ)

細胞アッセイ	細胞株	HepG2 Cells
	濃度	4-10 μmol/L
	反応時間	48 h
	実験の流れ	HepG2 human hepatocellular carcinoma cells 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.
