In the pineal of 21-day old male Wistar rats hydroxyindole-O-methyltransferase (HIOMT) activities involved in the synthesis of several 5-methoxyindoles were determined during the night in April, June, October and January. A high HIOMT activity for the synthesis of melatonin/5-methoxytryptophol was

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

The effects of different 5-methoxyindoles on the process of protein/peptide secretion characterized by the formation of granular vesicles (GV) have been studied in mouse pinealocytes maintained in explant culture. All 5-methoxyindoles studied clearly influence the number of granular vesicles in

The wild-type trp repressor of E. coli bound 5-methoxytryptophan, a Trp analogue, less tightly than Trp. A mutant repressor (Val58-->Ala) that should bind 5-methoxytryptophan preferentially to Trp was computationally designed by free-energy calculations accompanied by free-energy decomposition. The designed mutant
