Procainamide hydrochloride (Procaine amide hydrochloride) is a specific and potent inhibitor of DNA methyltransferase 1 (DNMT1), which reactivates the expression of tumor suppressor factors by demethylating tumor suppressor genes. Procainamide hydrochloride induces vacuolization in various cell types and reduces cell proliferation and migration. Procainamide hydrochloride relaxes airway smooth muscle by activating potassium channels. Procainamide hydrochloride can be used in cancer and arrhythmia research.

IC₅₀ & Target

DNMT1^[1]

All DNA Methyltransferase Isoforms :

In Vitro

Procainamide hydrochloride has a K_i of 7.2 μM for DNMT1 inhibition on hemimethylated oligonucleotide substrates and a K_i of 4600 μM for DNMT1 inhibition on unmethylated oligonucleotide substrates^[1].
Procainamide hydrochloride (0.5 mM; 96 h) causes loss of CpG methylation in HCT116 cells and affects centromeric repeat sequences and single-copy genes^[1].
Procainamide hydrochloride (0-10 mM) concentration-dependently relaxes bovine tracheal contractions induced by methacholine (0.3 μM) but does not significantly relax contractions induced by potassium ions (40 mM)^[4].
Procainamide hydrochloride (250 μM-2.5 mM; 0-48 h) does not induce cellular vacuolization at a dose of 250 μM, but induces cellular vacuolization in many cells at a dose of 2.5 mM^[5].
Procainamide hydrochloride (10 μM; 5 d) demethylates ER, p16, and RAR genes in MDA-231, T24, and MCF-7 cell lines^[6].

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

In Vivo

Procainamide hydrochloride (20 mg/kg; i.p.; once daily for 7 days) demethylates and re-expresses the ER gene in BALB/c mice xenografted with MDA-231 cells^[6].

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: ≥ 3.25 mg/mL (11.96 mM); Clear solution

This protocol yields a clear solution of ≥ 3.25 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (32.5 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: ≥ 3.25 mg/mL (11.96 mM); Clear solution

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (32.5 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: ≥ 3.25 mg/mL (11.96 mM); Clear solution

This protocol yields a clear solution of ≥ 3.25 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 (32.5 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.

Help & FAQs

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.
