Sixteen aromatic and aliphatic sulfamides and sulfamates were synthesized and tested in their inhibition to carbonic anhydrase CAII activity. The weaker inhibition pattern shown by sulfamides as compared to sulfamates is interpreted in this research by means of molecular modeling techniques, including known inhibitors (topiramate and its sulfamide cognate) in the analysis. The results nicely explain the origin of the inhibitory activity, which is not only related to positive interactions of the ligand with the active site residues but also to the solvation pattern characteristic of each ligand.

The present invention relates to a compound comprising an alpha-end and an omega-end, the compound comprising on the alpha-end a reactive group Qlcapable of reacting with a functional group F1present on a biomolecule and on the omega-end a target molecule, the compound further comprising a group according to formula (1) or a salt thereof: Said compound may also be referred to as a linker-conjugate. The invention also relates to a process for the preparation of a bioconjugate, the process comprising the step of reacting a reactive group Q1of a linker-conjugate according to the invention with a functional group F1of a biomolecule. The invention further relates to a bioconjugate obtainable by the process according to the invention. In a preferred embodiment, the invention concerns a process for the preparation of a bioconjugate via a cycloaddition, such as a (4+2)-cycloaddition (e.g. a Diels-Alder reaction) or a (3+2)-cycloaddition (e.g. a 1,3-dipolar cycloaddition).

H6P2W18O62is used as an efficient catalyst for the synthesis of novel N-substituted sulfonyl maleimides (1H-Pyrrole-2,5-diones) via the condensation of sulfonamide and maleic anhydride derivatives. The Dawson heteropolyacid was used with a catalytic amount of 2?mmol% in acetonitrile at reflux. The reuse of H6P2W18O62as heterogeneous catalyst several times without decrease in their activity, short reaction times, easy isolation of desired products with good to excellent yields shows the advantages of this novel methodology.

The synthesis of new series of pyrrolidine-2,5-diones having sulfonamide moieties is described. These compounds are synthesized in good yield in three steps (carbamoylation-sulfamoylation, deprotection and condensation) using a catalytic amount of H6P2W18O62 in acetonitrile under refluxing conditions.
