An enzymatic preparation from human brain converts tryptamine to tryptoline (9H-1,2,3,4-tetrahydropyrido(3,4-b)indole) in the presence of 5-methyltetrahydrofolic acid. Similarly, N-methyltryptamine and 5-hydroxytryptamine yield 1-methyltryptoline and 5-hydroxytryptoline, respectively. Neither in vitro nor in vivo formation of these compounds by human tissues has been described.

Active mechanism of DNA demethylation can be responsible for the activation of previously silenced genes. Products of 5-methylcytosine oxidation are released into the bloodstream and eventually excreted with urine. Therefore, whole-body epigenetic status can be assessed non-invasively on the basis of the urinary excretion of a broad spectrum of epigenetic modifications: 5-hydroxymethylcytosine ...

Twenty-three indole analogs were used to inhibit the growth of carrot and tobacco suspension cultures. The addition of tryptophan or indole partially reversed the inhibition of both cell lines only for 4-fluoroindole, 5-fluoroindole, and 6-fluoroindole. Inhibition of tobacco cell growth by 5-aminoindole, 5-methoxyindole, 6-methoxyindole, or 7-methoxyindole was also partially reversed. Previousl...
