Product Introduction

Bioactivity

Description	TMS (2,3',4,5'-Tetramethoxystilbene) is a very selective and potent competitive inhibitor of P450 1B1 (CYP1A1).
Targets&IC50	CYP1A1:300 nM (IC50), CYP1B1:3 nM (Ki), CYP1B1:6 nM (IC50), CYP1A2:3.1 μM (IC50)
In vitro	Twenty-four hours after incubation with the 10 μM DOX in the presence and absence of 0.5 μM TMS, approximately 1.5 × 106 cells per six-well culture plate were collected in 100 μl lysis buffer (50 mM HEPES, 0.5 M sodium chloride, 1.5 mM magnesium chloride, 1 mM EDTA, 10% glycerol (v/v), 1% Triton X-100, and 5 μl/ml of protease inhibitor cocktail).
In vivo	Mice were administered 300 μg/kg of selective inhibitor of P450 1B1, TMS or its vehicle (dimethyl sulfoxide), i.p. every third day for the duration of the experimental period

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
