A series of potential new 5-HT2 receptor scaffolds based on a simplification of the clinically studied, 5-HT2CR agonist vabicaserin, were designed. An in vivo feeding assay early in our screening process played an instrumental part in the lead identification process, leading us to focus on a 6,5,7-tricyclic scaffold. A subsequent early SAR investigation provided potent agonists of the 5-HT2C receptor that were highly selective in both functional and binding assays, had good rat PK properties and that significantly reduced acute food intake in the rat.
Facile in Vitro Biocatalytic Production of Diverse Tryptamines

Tryptamines are a medicinally important class of small molecules that serve as precursors to more complex, clinically used indole alkaloid natural products. Typically, tryptamine analogues are prepared from indoles through multistep synthetic routes. In the natural world, the desirable tryptamine synthon is produced in a single step by l-tryptophan decarboxylases (TDCs). However, no TDCs are known to combine high activity and substrate promiscuity, which might enable a practical biocatalytic route to tryptamine analogues. We have now identified the TDC from Ruminococcus gnavus as the first highly active and promiscuous member of this enzyme family. RgnTDC performs up to 96 000 turnovers and readily accommodates tryptophan analogues with substituents at the 4, 5, 6, and 7 positions, as well as alternative heterocycles, thus enabling the facile biocatalytic synthesis of >20 tryptamine analogues. We demonstrate the utility of this enzyme in a two-step biocatalytic sequence with an engineered tryptophan synthase to afford an efficient, cost-effective route to tryptamines from commercially available indole starting materials.

Several hydroquinolyl alcohols and amines were electrochemically oxidized in methanol in the presence of sodium methoxide and potassium iodide to afford the corresponding intramolecular cyclization products. Furthermore, several amino malonates were electrochemically oxidized to yield the corresponding heterocyclic compounds through an intramolecular carbon-carbon bond formation in the presence of sodium cyanide in methanol.
