  S-Glycosyl Primary Sulfonamides−A New Structural Class for Selective Inhibition of Cancer-Associated Carbonic Anhydrases

  摘要：

  In this paper, we present. a. new class of carbonic anhydrase (CA) inhibitor that was designed to selectively target the extracellular domains of the cancer-relevant CA isozymes. The aromatic moiety of the classical zinc binding sulfonamide CA inhibitors is absent from these compounds and instead they incorporate a hydrophilic mono- or disaccharide fragment directly attached to the sulfonamide group to give S-glycosyl primary sulfonamides (1-10). The inhibition properties of these compounds at the physiologically abundant human CA isozymes I and II and cancer-associated IX and XII were determined, and all compounds had moderate potency with KiS in the micromolar range. We present the crystal structures of anomeric sulfonamides 4, 7, and 10 and the sugar sulfamate drug topiramate in complex with human recombinant CA II. From these structures, we have obtained valuable insights into ligand-protein interactions of these novel carb ohydrate-based sulfonamides with CA.

  O-Peracetylated methyl 3-(D-glycopyranosylthio)propanoates of beta-D-gluco, and alpha- and beta-D-galacto configurations were oxidized to the corresponding S,S-dioxides (sulfones) by Oxone (R) or MCPBA. Oxidation of the beta-D-gluco derivative with H2O2/Na2WO4 gave the corresponding S-oxide (sulfoxide). DBU-induced elimination of methyl acrylate from the P-D-gluco and P-D-galacto configured SS-dioxides (sulfones) gave O-peracetylated beta-D-glycopyranosyl-1-C-sulfinates which, on treatment with H2NOSO3H, furnished the corresponding beta-D-glycopyranosyl-1-C-sulfonamides. Radical-mediated bromination of the protected methyl 3-(beta-D-glycopyranosylthio)propanoate S.S-dioxides gave mixtures of 1-C- and 5-C-bromoglycosyl compounds. Similar brominations of the O-peracetylated beta-D-glycopyranosyl-1-C-sulfonamides resulted in the formation Of U-D-glycopyranosyl bromides and 1-C- and 5-C-bromoglycosyl sulfonamides. A rationale for these observations was proposed. Methyl 3-(beta-D-glucopyranosylthio)propanoate, its S,S-dioxide, and beta-D-glucopyranosyl-1-C-sulfonamide proved inefficient when tested as inhibitors of rabbit muscle glycogen phosphorylase b.

  The synthesis of S-glycosyl sulfonamides wherein the primary sulfonamide functional group (-SO2NH2) is directly attached to the anomeric position of a carbohydrate moiety is reported. Our general approach consists of first introducing a thioacetate group at die anomeric center of a per-O-acetylated sugar derivative. From this follows formation of a glycosyl sulfenamide (sugar-SNR2), oxidation of the sulfenamide to give a glycosyl N-protected sulfonamide (sugar-SO2NR2), and removal of the sulfonamide protecting (R) group to yield a primary sulfonamide at the anomeric center (sugar-SO2NH2). A variety of mono- and disaccharide derivatives were synthesized using this new methodology.
