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

IC50: 300 nM (MLCK)^[1]

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].

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].

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.
