Sulfonamides is a generic term that includes following cases, Antibacterial compounds that are aniline substituted Sulfonamides: Sulfanilamides e.g. Sulfamethoxazole [4-amino-N- (5-methyl-1,2-oxazol-3-yl)benzenesulfonamide]. Prodrugs that produce active sulfanilamides e.g. Succinyl sulfathiazole. Non aniline Sulfonamides e.g. Mefenide The sulfonamide group is a non-classical bioisostere of carboxyl groups, phenolic hydroxyl groups and amide groups. This review highlights that most of the bioactive substances have the sulfonamide group, or a related group such as sulfonylurea, in an orientation towards other functional groups Sulfonamides Classification There are generally thought to be two major classifications of sulfonamide medications based upon their chemical structure. Most commonly they're bacteriostatic..
Sulfonamides As the name suggests, the sulfonamide (or sulphonamide) class of antibacterials contain a sulfonamide group. Sulfonamides are synthetic antibacterial agents and are sometimes referred to as sulfa drugs. Prontosil is a red dye that was found to possess antibacterial properties against certain bacteria during in vivo studies 13 3) Non-sulfonamide Loop Diuretics Ethacrynic acid is a phenoxyacetic acid derivative which is the only important member of this class of drugs. C Cl Cl OCH2COOHCCH2CH3 O CH2 Ethacrynic acid 1 23 4 Structure Activity Relationship Ø Activating group (Cl- or CH3-) occupy either the 3 position or the 2 and 3 positions Let's get started by looking at the structure of sulfonamides. Sulfonamides are composed of a sulfur atom that has two sets of double bonds to two oxygen atoms, a carbon-based side group, and a.. The topic of antibiotics is extensive, and so in this course we shall focus on two main classes; the sulfonamides, and the β-lactams. The latter include the penicillins and cephalosporins, which are still widely used today despite the growing problem of resistance, as bacteria evolve effective biochemical defences against these drugs Unfortunately in medicinal chemistry this classification has the disadvantage that members of the same group often exhibit different types of pharmaceutical activity. Steroids, for example, have widely differing activities: testosterone is a sex hormone, spironolactone is a diuretic and fusidic acid is an antibacterial agent (Fig. 1.16)
Sulfadiazine is a sulfonamide consisting of pyrimidine with a 4-aminobenzenesulfonamido group at the 2-position.

Since ancient times people have been using potions, natural products and even the dust of mummies for the treatment of health problems. The healing effects of remedies were often ascribed to spirits and mythical entities, but. Sulfonamide derivatives are frequently seen structural motifs in medicinal chemistry. Almost a century after Gerhard Domagk's pioneering work leading to the first sulfonamide antibiotic Prontosil, sulfa-drugs are still widely utilized in various pharmaceutical applications due to their antibacterial, antiviral, antimalarial, antifungal.
