Molarity Calculator

Cl-amidine hydrochloride 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 hydrochloride induces apoptosis in cancer cells. Cl-amidine hydrochloride induces microRNA (miR)-16 (miRNA-16, microRNA-16) expression and causes cell cycle arrest. Cl-Amidine hydrochloride prevents histone 3 citrullination and neutrophil extracellular trap formation, and improves survival in a murine sepsis model.

Description

IC₅₀ & Target

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

In Vitro

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 prevents histone 3 citrullination and neutrophil extracellular trap formation, and improves survival in a murine sepsis model^[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:	0, 5, 10, 15, 20, 25, 50 μg/mL.
Incubation Time:	24 h.
Result:	Induced apoptosis dose-dependently.

In Vivo

Cl-amidine (75 mg/kg, ip once daily) suppresses and treats DSS-induced colitis in mice^[2].
Cl-amidine (5, 25, 75 mg/kg, oral gavage, once daily) leads to significant reductions in the histology scores dose-dependently^[2].

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

Animal Model:	C57BL/6 mice (8-12 wk old, DSS mouse model of colitis)^[2].
Dosage:	75 mg/kg.
Administration:	IP once daily.
Result:	Suppressed PAD activity, protein citrullination, and PAD levels in the colon in vivo.

Animal Model:	C57BL/6 mice (8-12 wk old, DSS mouse model of colitis)^[2].
Dosage:	5, 25, 75 mg/kg.
Administration:	Oral gavage once daily.
Result:	Led to significant reductions in the histology scores.

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: ≥ 1.25 mg/mL (3.60 mM); Clear solution

This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1.25 mg/mL (3.60 mM); Clear solution

This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 1.25 mg/mL (3.60 mM); Clear solution

This protocol yields a clear solution of ≥ 1.25 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 (12.5 mg/mL) to 900 μL Corn oil, and mix evenly.

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: 5.5 mg/mL (15.84 mM); Clear solution; Need ultrasonic
