Cl-amidine TFA is an orally active peptidylarginine deminase (PAD) inhibitor, with IC₅₀ values of 0.8 μM, 6.2 μM and 5.9 μM for PAD1, PAD3, and PAD4, respectively. Cl-amidine TFA induces apoptosis in cancer cells. Cl-amidine TFA induces microRNA (miR)-16 (miRNA-16, microRNA-16) expression and causes cell cycle arrest. Cl-Amidine TFA prevents histone 3 citrullination and neutrophil extracellular trap formation, and improves survival in a murine sepsis model.

製品説明

IC₅₀ & Target

IC50: 0.8 μM (PAD1), 5.9 μM (PAD4), 6.2 μM (PAD3)^[1]^[5].

体外実験

Cl-amidine is a bioavailable haloacetamidine-based compound that inhibits all the active PAD isozymes with near equal potency (k_inact/K_I=13,000 M_-1 min-1 for PAD4)^[1].
Cl-amidine (0, 5, 10, 15, 20, 25, 50 μg/mL, 24 hours) induces apoptosis in TK6 lymphoblastoid cells and HT29 colon cancer cells in a dose-dependent manner. Interestingly, the colon cancer cell line (HT29) is relatively resistant to apoptosis caused by Cl-amidine^[2].
Cl-amidine irreversibly inactivates PADs by covalently modifying an active site cysteine that is important for its catalytic activity^[4].

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

Apoptosis Analysis^[2].

Cell Line:

TK6 lymphoblastoid cells and HT29 colon cancer cells.
Concentration:

Result:

Induced apoptosis dose-dependently.

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: ≥ 0.67 mg/mL (1.58 mM); Clear solution

This protocol yields a clear solution of ≥ 0.67 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (6.7 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: ≥ 0.67 mg/mL (1.58 mM); Clear solution

This protocol yields a clear solution of ≥ 0.67 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (6.7 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: ≥ 0.67 mg/mL (1.58 mM); Clear solution

This protocol yields a clear solution of ≥ 0.67 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 (6.7 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
