Methoxyindoles of the retina.
Melatonin and other 5-methoxyindoles are compounds usually associated with the pineal gland. Research is expanding from studies of pineal melatonin to studies of extrapineal organs and of other 5-methoxyindoles besides melatonin. Research in recent years has shown that the retina also contains and synthetises 5-methoxyindoles. The biochemical modes of action are still unclear. Nevertheless, they seem to have physiological roles in the pineal gland and the retina. These compounds are thought to participate in the regulation of the cyclic metabolism of the retina. Melatonin and other 5-methoxyindoles are often classified as neuromodulators.
