| Mechanism of Action | MLCK inhibitors block the phosphorylation of myosin light chains, thereby reducing cytoskeletal contraction and stabilizing tight junctions at the blood-brain barrier and endothelial surfaces. This mechanism reduces vascular permeability and preserves barrier integrity in conditions characterized by excessive leakage or cytoskeletal dysfunction. |
