Sulfonamide drug testing

Sulfonamide drugs are artificially synthesized antibacterial drugs that have been used in clinical practice for nearly 50 years. They have advantages such as a wide antibacterial spectrum, stable properties, simple use, and no food consumption during production. Especially after the discovery of the antibacterial enhancer - trimethoprim (TMP) in 1969, its combined use with sulfonamides can enhance its antibacterial effect and expand its therapeutic range. Therefore, although a large number of antibiotics have been introduced, sulfonamides are still important chemotherapeutic drugs. A class of artificially synthesized antibacterial drugs. In 1932, G.J.P. Domark discovered that Bailongduoxi can control streptococcal infections. In 1935, sulfonamide drugs were officially applied in clinical practice. It has the advantages of wide antibacterial spectrum, stable properties, wide distribution in the body, no need for grain as raw material for manufacturing, large yield, multiple varieties, low price, easy use, and sufficient supply. Although there are currently many effective antibiotics, sulfonamide drugs still have important value in controlling various bacterial infections, especially in managing acute urinary tract infections. Sulfonamide drugs are prone to develop resistance, and their metabolite acetylsulfonamide in the liver has low solubility, which can easily precipitate crystals in the urine and cause kidney toxicity. Therefore, when using drugs, it is necessary to strictly control the dosage and time, take sodium bicarbonate together, and drink plenty of water. The commonly used sulfonamide drugs in clinical practice are derivatives based on para aminobenzenesulfonamide (referred to as sulfonamide), which can be substituted by different heterocycles to form different types of sulfonamide drugs. Compared with the parent sulfonamide, they have advantages such as high potency, low toxicity, wide antibacterial spectrum, and easy absorption after oral administration. The free amino group in the opposite position is the antibacterial active part, and if replaced, it loses its antibacterial effect. It is necessary to release the amino group again after decomposition in the body in order to restore activity
