  Novel tryptophan dioxygenase inhibitors and combined tryptophan dioxygenase/5-HT reuptake inhibitors

  摘要：

  Tryptophan dioxygenase (TDO) is a liver enzyme that is responsible for the majority of the metabolism of tryptophan. A series of novel 3-(2-pyridylethenyl)indoles are shown to be potent inhibitors of TDO with selected members of the series also having 5-hydroxy tryptamine (5-HT) reuptake inhibitory activity. These compounds are shown to provide significant increases in the levels of tryptophan and 5-HT in the cerebrospinal fluid and are thus of interest for antidepressant therapy.

  Polycyclic indolines and indolenines were synthesized via base-catalyzed intramolecular dearomatizing 3-alkenylation reactions of alkynyl indoles 1 at room temperature. The base enhanced the nucleophilicity of the carbon at the 3-position of the indole moiety, facilitating an exclusive 5-exo-dig cyclization reaction with the alkyne to form spiroindolenines 2.

  日期：2017.12

  An efficient iron-catalyzed C3-selective formylation of free (N–H) or N-substituted indoles was developed by employing formaldehyde and aqueous ammonia, with air as the oxidant. This new method gave 3-formylindoles in moderate to excellent yields with fairly short reaction times. Moreover, this procedure for catalytic formylation of indoles can be applied to gram-scale syntheses.
