Request more information

Denatonium benzoate (THS-839) is known as the most bitter compound and is commonly used as a deterrent (bittering agent) to activate different types of bitter taste receptors (TAS2Rs) with oral activity. Denatonium benzoate can enhance insulin secretion, has anti-inflammatory effects, and promotes allergy susceptibility .

For research use only. We do not sell to patients.

Incubation Time:	24 h
Result:	Showed that 0.1 mM caused significant inhibition of cell viability in RBL-2H3 and KU812 cells in a dose-dependent manner.

Western Blot Analysis^[2]

Cell Line:	RBL-2H3, KU812
Concentration:	10 mM
Incubation Time:	30 min
Result:	Promoted the expression of FcεRIα on the surface of mast cells.

In Vivo

Denatonium benzoate (15mg/kg, intraperitoneal injection, single dose) can reduce the initial stage of foot inflammation in rats induced by histamine^[1].
Denatonium benzoate (5 mg/kg, i.g., single dose) promotes allergy susceptibility in mice^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Rat plantar edema model^[1]
Dosage:	15 mg/kg, single dose
Administration:	Intraperitoneal injection (i.p.)
Result:	Reduced foot volume and had anti-inflammatory effects.

Animal Model:	BLAB/c mice induced by OVA^[2]
Dosage:	5 mg/kg, every other day, 20 days
Administration:	i.g.
Result:	Caused more severe allergic reactions and promoted allergic susceptibility in mice. Acute diarrhea began after three to four intragastric stimulations, mucus accumulation in the jejunum, β-hex and histamine levels were significantly increased, and ova in serum Specific IgE levels are also elevated.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2 mg/mL (4.48 mM); Clear solution

This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: PBS
Solubility: 33.33 mg/mL (74.63 mM); Clear solution; Need ultrasonic
