Various sulfonyl-containing compounds (e.g. sulfonamides, sulfones) bind at human 5-HT6 serotonin receptors, but it has been difficult relating the binding mode(s) of such agents to one another, even though many possess a common SO2 moiety, to identify a common pharmacophore model(s). On the basis of the hypothesis that an ergoline-type conformation might be important for the binding of some sulfonamide-containing arylalkylamines, we prepared for examination at h5-HT6 receptors a series of compounds, including phenylethylamines 6, pyrroloethylamine 7, and phenylpiperazines 9. The results (with Ki values ranging from about 1 nM to > 1000 nM) suggest that many of these agents likely bind in a related fashion, and structure-affinity studies indicate that the benzenesulfonamide portion of the phenylethylamine and phenylpiperazine analogues can be "reversed", abbreviated to a sulfone, and moved to an adjacent position with relatively little impact on affinity. Although a benzenesulfonamide (or related arylsulfonamide) group might be common to various 5-HT6 ligands, there appears to be some latitude with regard to the specific constitution and location of the sulfonamide moiety even within the same arylalkylamine structural framework. A pharmacophore model is presented to account for some of the current findings.

In the reaction of p-halogenobenzyl cyanides with sodium thiophenolate under the conditions of an SRN1 reaction the intermediately formed radical-anion undergoes fragmentation in two concurrent directions, i.e., with elimination of the cyanide ion and with elimination of the halide ion.The presence of the two fragmentation paths was used as evidence for the radical-anion nature of the intermediates in the carbonylation of aryl halides.
