Until now the day/night and seasonal rhythmicity in the synthesis of 5-methoxyindoles (MI) is thought to be regulated by environmental factors, especially photoperiod and temperature. Endogenous factors are also implicated in the generation of N-acetyltransferase and hydroxyindole-O-methyltransferase activity rhythms. 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

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

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
