ABSTRACT
The N-benzylphenethylamines (NBOMes) are a class of ligands from which compounds with impressive selectivity for the serotonin 2A receptor (5-HT2AR) over the closely related serotonin 2C receptor (5-HT2CR) have emerged. These include 4-(2-((2-hydroxybenzyl)amino)ethyl)-2,5-dimethoxybenzonitrile (25CN-NBOH, 1) and 2-(2,5-dimethoxy-4-bromobenzyl)-6-(2-methoxyphenyl)piperidine (DMPMBB, 2). The present work entails the synthesis and characterization of ligands wherein the structures of these two molecules have been fused. The desired compounds were accessed by a six-step synthetic procedure followed by the chiral resolution of the resulting racemic mixtures, giving one active ((S,S)-3) and three essentially inactive stereoisomers. In silico experiments support that one of the four possible stereoisomers would be active. Further in silico investigations showed that 1, 2, and (S,S)-3 share a common binding mode, further supporting the shared stereochemistry between the active enantiomer ((S,S)-3) and 2.
