Domiphen bromide is a cationic active quaternary ammonium salt and also an inhibitor of HERG channels (IC₅₀: 9 nM), aminopeptidase-like enzymes, Escherichia coli alkaline phosphatase, and α-chymotrypsin. Domiphen bromide has multiple activities such as antibacterial, antimalarial, and disinfectant properties, and it is also a synergist of Colistin (HY-113678). Domiphen bromide can be used as a chemical preservative and a cationic surfactant, and it can also be used in the research of bacterial infectious diseases such as pharyngitis, thrush, and oral ulcers.

Biological Activity

Description

All Parasite Isoforms :

In Vitro

Domiphen bromide (20 µM; 8-24 h) can inhibit the growth of Plasmodium falciparum, block the production of MEP, and simultaneously reduce the levels of multiple intermediates in the citric acid cycle and activate the glycolysis pathway^[1].
Domiphen bromide (0.01-10 μM; 0-18 h) can inhibit contraction parameters, prolong the field potential duration, and cause tachycardia/fibrillation-like oscillations in human induced pluripotent stem cell-derived cardiomyocytes^[2].

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

In Vivo

Domiphen bromide (1.28-12.85 mg/kg; intravenous injection; single dose) has certain cardiotoxicity in rabbits. Rabbits show good tolerance at a dose of 1.28 mg/kg^[2].
Domiphen bromide (20 mg/kg; intraperitoneal injection; single dose) in combination with Colistin (HY-113678) exhibits antibacterial activity in a mouse model infected with K. pneumonia FK6556^[3].

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

Stock Solution Working Solution

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: ≥ 2.5 mg/mL (6.03 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: 2.5 mg/mL (6.03 mM); Suspended solution; Need ultrasonic

This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (6.03 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Working 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.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
