Hydroxydiosmin shows remarkable pharmacological activity and clinical potential in the optimization of venoprotective function, and its mechanism of action and research progress are mainly reflected in the following aspects:
1. Enhancement of venous tone and improvement of venous function
Mechanism of action: Hydroxydeosmin improves venous leakage and maintains the integrity of venous endothelium in a dose-dependent manner. Studies have shown that it can inhibit cell gap dilatation caused by venous hypertension and reduce the increase in vascular permeability, thereby reducing the level of inflammatory stress caused by venous occlusion.
Clinical significance: In the treatment of chronic venous disease (CVD), hydroxydeosmin significantly improves symptoms of venous insufficiency, such as venous edema and soft tissue swelling, by enhancing venous tone and reducing venous dilatation.
2. Protecting vascular endothelium and maintaining venous integrity
Mechanism of action: Hydroxydiosmin protects vascular endothelium from damage by regulating the expression of endothelial barrier proteins, such as ZO-1. and maintaining intercellular junctions. Studies have shown that it can effectively inhibit endothelial damage caused by iliac vein occlusion and reduce vascular leakage.
Clinical significance: In the state of venous hypertension, hydroxydiosmin reduces the risk of complications such as varicose veins and thrombophlebitis by protecting the integrity of the vascular endothelium.
3. Regulation of muscular system damage and improvement of venous ulcers
Mechanism of action: Hydroxydiosmin improves muscular system damage by regulating actin filament organization and muscle contraction. Research shows that it can maintain the contraction function of peripheral muscles and promote the healing of venous ulcers.
Clinical significance: In the treatment of venous ulcers, hydroxydiosmin provides new therapeutic ideas for refractory conditions such as venous ulcers of the lower limbs by improving muscle function and enhancing local blood circulation.
4. Dose-dependent efficacy and safety
Mechanism of action: The venoprotective function of hydroxydeosmin shows dose-dependence. The study showed that the high dose group (40mg/kg/day) was superior to the low dose group (20mg/kg/day) in protecting vascular permeability, eliminating the increase in perfusion ratio and maintaining venous cell integrity.
Clinical significance: High-dose hydroxydeosmin has better efficacy in CVD treatment, and the increase in drug dose did not bring about an increase in adverse effects, showing better hepatic and renal safety.
5. Combination therapy and multi-target synergism
Mechanism of action: Hydroxydiosmin can be used in combination with other drugs to enhance the efficacy through multi-target synergism. For example, its combination with hesperidin can further improve venous function and reduce inflammatory reaction.
Clinical significance: In the treatment of complex venous diseases, hydroxydiosmin can improve the therapeutic efficacy and reduce drug tolerance through multi-pathway regulation by combination.
