Sulfonamides and trimethoprim [PDF]

open access: yesExpert Review of Anti-infective Therapy, 2009
Sulfonamides and trimethoprim are inexpensive and effective antibacterial drugs that have been used extensively. The use of sulfonamides for systemic use has, however, decreased dramatically for several years, mainly because of resistance development in pathogenic bacteria and allergic side effects. Also the clinical efficiency of trimethoprim has been

Deconstructing Protein Binding of Sulfonamides and Sulfonamide Analogues

open access: yesJACS Au, 2023
Sulfonamides are one of the most important pharmacophores in medicinal chemistry and sulfonamide analogs have gained substantial interest in recent years. However, the protein interactions of sulfonamides and especially of their analogs are underexplored.
