Sulfanilamide (also spelled sulphanilamide) is a sulfonamide antibacterial drug. Chemically, it is an organic compound consisting of an aniline derivatized with a sulfonamide group. [ 1 ] Powdered sulfanilamide was used by the Allies in World War II to reduce infection rates and contributed to a dramatic reduction in mortality rates compared to ...
Many important drugs contain the sulfonamide group. [1] A sulfonamide (compound) is a chemical compound that contains this group. The general formula is R−SO 2 NR'R" or R−S(=O) 2 −NR'R", where each R is some organic group; for example, "methanesulfonamide" (where R = methane, R' = R" = hydrogen) is CH 3 SO 2 NH 2.
Sulfonamide functional group Hydrochlorothiazide is a sulfonamide and a thiazide. Furosemide is a sulfonamide, but not a thiazide. Sulfamethoxazole is an antibacterial sulfonamide. Sulfonamide is a functional group (a part of a molecule) that is the basis of several groups of drugs, which are called sulphonamides, sulfa drugs or sulpha drugs.
Then an excess but fixed volume of sulfanilamide and N-(1-naphthyl)ethylenediamine dihydrochloride solution is added. With nitrous acid as the limiting reagent, the azo coupling reaction produces an azo dye quantitatively with respect to the nitrite ions:
Sulfenamides have been characterized by X-ray crystallography.The S-N bond in sulfenamides is a chiral axis that leads to formation of diastereomeric compounds. The existence of these distinct stereoisomers is due to the formation of a partial double bond between either sulfur or nitrogen's lone pair and the other atom's antibonding orbitals. [1]
Chemical structure of a generic acylsulfonamide. Acylsulfonamide is a functional group in organic chemistry that is sometimes used in medicinal chemistry. [1] It consists of a sulfonamide group (SO 2 NH) linked to an acyl group (RCO), forming the structure R 1-CO-NH-SO 2-R 2.
General chemical structure of a sulfanilide. In organic chemistry, a sulfonanilide group is a functional group found in certain organosulfur compounds.It possesses the chemical structure R−S(=O) 2 −N(−C 6 H 5)−R', and consists of a sulfonamide group (R−S(=O) 2 −NR'R") where one of the two nitrogen substituents (R' or R") is a phenyl group (C 6 H 5).
Sulfamethoxazole, a sulfanilamide, is a structural analog of para-aminobenzoic acid (PABA). They compete with PABA to bind to dihydropteroate synthetase and inhibit conversion of PABA and dihydropteroate diphosphate to dihydrofolic acid, or dihydrofolate.
