Description

ML-7 hydrochloride is a naphthalene sulphonamide derivative, potently inhibits MLCK (IC₅₀=300 nM). ML-7 hydrochloride also inhibits YAP/TAZ.

IC₅₀ & Target

IC50: 300 nM (MLCK)^[1]

In Vitro

ML-7 hydrochloride inhibits rabbit portal vein α1-adrenoceptor NSCC with IC₅₀ of 0.8 μM^[1]. The myosin light chain kinase (MLCK) inhibitor ML-7 hydrochloride (3 μ M and 10 μM) also attenuates the Dexmedetomidine (DMT)-induced contraction (p<0.05 versus control)^[2].

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

In Vivo

In sham operated animals Evans Blue extravasation is not different between ML-7 hydrochloride and vehicle group (sham+vehicle: 0.26±0.02 OD/g; sham+ML-7: 0.26±0.02 OD/g). After CCI inhibition of MLCK with ML-7 results in a significant lower amount of intracerebral Evans Blue compared to vehicle treated animals (CCI+vehicle: 0.42±0.04 OD/g; CCI+ML-7: 0.35±0.05 OD/g, p=0.048)^[3].

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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1.67 mg/mL (3.69 mM); Clear solution

This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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 2

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 1.67 mg/mL (3.69 mM); Clear solution

This protocol yields a clear solution of ≥ 1.67 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 (16.7 mg/mL) to 900 μL Corn oil, and mix evenly.

The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only. If necessary, please contact MedChemExpress (MCE).

Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.

If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

Animal Administration
^[3]

Mice^[3]
Mice are treated with intraperitoneal injection of the selective MLCK inhibitor ML-7 (1 mg/kg) or vehicle solution (0.9% NaCl, control group) 1 h prior to and 6 h after trauma. Hemispheric brain water content and neurological function are measured 24 h after controlled cortical impact (CCI) in animals randomized to: (i) vehicle+sham surgery, (ii) vehicle+CCI, (iii) ML-7+sham surgery or (iv) ML-7+CCI (n=8 per group) and 15 min after CCI in animals randomized to: (i) vehicle+sham surgery, (ii) vehicle+CCI, (iii) ML-7+sham surgery or (iv) ML-7+CCI (n=6 per group). Mice are treated with intraperitoneal injection of the selective MLCK inhibitor ML-7 (1 mg/kg) or vehicle solution (0.9% NaCl, control group) 1 h prior to and 6 h after trauma. Evans Blue extravasation is determined 24 h after surgery in animals randomized to: (i) vehicle + CCI or (ii) ML-7+CCI (n=5 per group) and in animals randomized to (iii) vehicle + sham surgery or (iv) ML-7+sham surgery (n=6 per group). ICP is measured 24 h CCI and sham surgery.
