Pharmacol. In vivo sulfonamides exhibit a range of pharmacological activities, such as anti-carbonic anhydrase and anti-t dihydropteroate synthetase allowing them to play a role in treating a diverse range of disease states such as diuresis, hypoglycemia, thyroiditis, inflammation, and glaucoma . It (also spelled sulphur) is a chemical element with the symbol S and atomic number 16. Sulfonamides are an important class of therapeutic agents. Sulfanilamide and its derivatives are popularly known as sulfonamide or sulfa drug. Abstract A theoretical study at the Hartree-Fock and density functional theory levels is performed on sulfonamide-type bacteriostatic compounds with the aim to provide an . Sulfonamides, as a group of antibiotics, work by inhibiting the bacterial synthesis of folate. Sulfonamides (SAs) are one of the broadly used antibiotics in domestic animal operations and have a notable potential of entering the environment through animal manure management practices. Sulfanilamide is a synthetic (man-made) sulfonamide that was first prepared in the early 1900's. It is an antibacterial sulfonamide and was actually used by the Allies during World War II to help.
