BACKGROUND The -SO2NH- group is of great significance in modern pharmaceutical use since in sulfa-drugs it is possible to introduce easily chemical modifications, and even small changes may lead to an improved version of an already existing drug. OBJECTIVE This paper aims to describe updated information in the sulfonamide field with a particular focus on new mechanisms of action, especially if discovered employing computational approaches. METHODS Research articles that focused on the use of the sulfonamide moiety for the design, synthesis, and in vitro/in vivo tests of various diseases were collected from various search engines like PubMed, Science Direct, Google Scholar, and Scopus, using keywords like sulfonamide moiety, aryl/heteroarylsulfonamides, alkylsulfonamides, in silico drug design. CONCLUSION The more relevant reports highlighting the prominent role of sulfonamide moiety in drug discovery have been critically analyzed. Sulfonamides can be considered as "molecular chimera" which are found to form hydrogen bonds as well as interact with unipolar environments within proteins. Therefore, based on the analysis reported herein, it is strongly foresight that new entities can be developed easily to improve the available machinery helpful in the fight of new and emerging diseases.
