Isosteric exchange of the acylsulfonamide moiety in Abbott's Bcl-XL protein interaction antagonist

Bioorg Med Chem Lett. 2008 Jul 15;18(14):4115-7. doi: 10.1016/j.bmcl.2008.05.096. Epub 2008 May 29.

Abstract

A multi-component reaction strategy was used for the fast and efficient synthesis of amide isosteres of known Bcl-2 inhibitors capable of disrupting protein-protein interactions. Ugi reaction and a subsequent nucleophilic aromatic substitution reaction provide a versatile path to libraries of compounds similar to Abbott's acylsulfonamides. Modeling arguments are used to explain the inferior activity of the amide as opposed to the sulfonamide series.
