β-N-Biaryl ether sulfonamide hydroxamates as potent gelatinase inhibitors: Part 1. Design, synthesis, and lead identification

Abstract A new series of β- N -biaryl ether sulfonamide hydroxamates as novel gelatinase inhibitors is described. These compounds exhibit good potency for MMP-2 and MMP-9 without inhibiting MMP-1. The structure–activity relationships (SAR) reveal the biaryl ether type P1′ moiety together with methanesulfonamide is the optimal combination that provides inhibitory activity of MMP-9 in the single-digit nanomolar range.
