Isosteric exchange of the acylsulfonamide moiety in Abbott’s Bcl-X(L) protein interaction antagonis
June 29th, 2008 | by admin |Isosteric exchange of the acylsulfonamide moiety in Abbott\’s Bcl-X(L) protein interaction antagonist.
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.
