Solid-phase parallel synthesis and SAR of 4-amidofuran-3-one inhibitors of cathepsin S: Effect of sulfonamides P3 substituents on potency and selectivity
4-amidofuran-3-one inhibitors of cathepsin S are described. The synthesis and structure–activity relationship of a series of inhibitors with a sulfonamide moiety in the P3 position is presented. Several members of the series show sub-nanomolar inhibition of the target enzyme as well as an excellent selectivity profile and good cellular potency. Molecular modeling of the most interesting inhibitors describes
Despite the widespread occurrence of pyridinesulfonicacid and pyridinesulfonamide functional groups in drugs and pharmaceuticals, and their use as ligands in metal–organic frameworks, a systematic structural study of their hydrogen bonding and molecular packing is lacking. We discuss crystal structures of 2-, 3-, and 4-pyridinesulfonic acids/amides in terms of N+–H···O– hydrogen bonds, N–H···O dimer/catemer

The cationic grid, [Cu(1,2-bis(4-pyridylethane)2)(H2O)2]2+]n, and the complex anion, Cu(4-pySO3)4(H2O)2]2−, neither of which have been previously observed, form a perfectly complementary supramolecular pair with respect to charge and H-bonding, to mutually stabilize each others formation.
