KAVERGAL
Product ID L6222 
Name KAVERGAL 
Molecular formula (C15H13O6)-[C15H12O7]n-(C15H13O6)
Description

It is an anti-hypoxic. It acts on the mitochondrial respiratory chain and it prevents atherosclerosis. It is also an angioprotector.


Sum of polymerized Proantocyanides , from the plants of Fabaceae family
Biological activity

It delays animal death caused by anoxia hyperbar (HH), normobar (NH), cytotoxic (CH) and total (isolated heart). Its antihypoxic activity, which is greater than that of Gutimine, Isothiobarbamine and Dibunol, is due to its action on the mitochondrial respiratory chain. In heart muscle mitochondria, in anoxia conditions and in presence of Kavergal, the degradation speed of Succinate and Glutamate is 1.5-2 fold higher and phosphorilation speed of ADP is 19-24 % higher than with the standard.

It has a potent cardioprotector action: The necrosis is reduced by 46 % in weight in rats under experimental infarction and by 60 % in rabbits under infarction due to cholesterol atherosclerosis. Its cardioprotector action under ischaemia conditions is linked with the inhibition of the peroxidative oxidation of lipids: in rats under 24 hours lasting myocardial infarction, decreases the ratio of final products in both ventricles. In rabbits under atherosclerosis due to cholesterol, decreases 3 fold the aorta indices of atherosclerotic infection and cholesterolemia.

It increases the alpha cholesterol ratio in serum.
