Designing rapid onset selective serotonin re-uptake inhibitors. Part 3: Site-directed metabolism as a strategy to avoid active circulating metabolites: structure-activity relationships of (thioalkyl)phenoxy benzylamines

Bioorg Med Chem Lett. 2008 Oct 1;18(19):5303-6. doi: 10.1016/j.bmcl.2008.08.040. Epub 2008 Aug 14.

Abstract

A series of thio-alkyl containing diphenylethers were designed and evaluated, as a strategy to competitively direct metabolism away from unwanted amine N-demethylation and deliver a pharmacologically inactive S-oxide metabolite. Overall, sulfonamide 20 was found to possess the best balance of target pharmacology, pharmacokinetics and metabolism profile.
