5-ZATRYPTAMINE ANALOGS AS h5-HT6 SEROTONIN RECEPTOR LIGANDS
摘要:
5-Aza analogs were prepared of several tryptamine derivatives and a skatole derivative known to bind at human 5-HT6 receptors and evaluated to determine if they bind in a manner similar to their indolic analogs. In general, the azatryptamines did not behave exactly like their tryptamine counterparts, but the behavior of NI-benzenesulfonyl analogs was reminiscent of the known arylsulfonyltryptamines. For example, N-1-(4-aminobenzenesulfonyl)-5-azaskatole (18; K-i = 41 nM) displayed an affinity comparable to N-1-(4-aminobenzenesulfonyl)skatole.

as the starting substrate for a variety of alkaloid biosynthetic pathways, by replacing the indole with one of four aza-indole isomers. We show that two aza-tryptamine substrates can be successfully incorporated into the products of the monoterpeneindolealkaloid pathway inCatharanthus roseus.
