Biaryl sulfonamides are excellent candidates for the azologization approach that yields photoswitchable drugs more active in their metastable cis state, compared to stable trans state.

Enantioselective modification of sulfonamides and sulfonamide-containing drugs via carbene organic catalysis is disclosed. The cation?? interaction was computationally found to play a pivotal role in modulating the reaction enantioselectivity.

Two synthetic routes to sulfondiimidamides have recently been reported. The ability prepare and manipulate sulfondiimidamides, which are the double aza-analogs of sulfonamides, in an efficient predictable way, opens new possibilities for exploring chemical space.

Sulfonamides and trimethoprim have been used for many decades as efficient and inexpensive antibacterial agents for animals and man. Resistance to both has, however, spread extensively and rapidly. This is mainly due to the horizontal spread of resistance genes, expressing drug-insensitive variants of the target enzymes dihydropteroate synthase and dihydrofolate reductase, for sulfonamide and t...

Furosemide, one of the most used diuretic drugs, rarely induces type-1 allergic reactions It is included in the non-aromatic sulfonamides but a cross-reactivity mechanism between this group and the sulfonamides antibiotics, has not been clearly demonstrated. A 24-year-old woman, 10 minutes after the intake of one pill of Seguril 40mg experienced oral itching, generalized urticaria, facial angio...

ortho-Lithiation of cyclic aryl sulfonamides in the presence of phosphoryl chloride provides a very simple entry to fused polycyclic sultams (benzothiazolines and naphthathiazolines).
