Coumarins, aldose reductase inhibitors

Flavonoids and related phenols, such as catechins and coumarins have been found to be aldose reductase inhibitors. Compounds containing a... [Pg.175]

Lens aldose reductase has been implicated in the pathogenesis of cataracts in diabetic and galac-tosemic animals. The enzyme catalyzes the reduction of glucose and galactose to their polyols, which accumulate in large quantities in the lens and ultimately lead to mature lens opacities. Several key bioflavones have activity against this enzyme. Oral administration of quercitrin decreased the accumulation of sobital in the lens. Therefore, the accumulation of lens opacities could be partially abrogated by certain flavonoids. In a study of 30 flavones, 4 isoflavones, and 13 coumarins, many potent inhibitors were found, but 5,7,3, 4 -tetrahydroxy-3,6-dimethoxyflavone and 6,3, 4 -trihy-droxy-5,7,8-trimethoxyflavone were especially active. [Pg.335]
