Prodrugs of sulfacetamide: Synthesis, X-ray structure, Hirshfeld analysis, antibacterial assessment, and docking studies
2022
Abstract New prodrugs of sulfacetamide as azo compounds were synthesized and have been evidenced through elemental and spectral analyses. Their synthesis was carried out by coupling the diazonium salt of sulfacetamide with activated carbanion salt of ethyl acetoacetate at 0 ˚C to afford the hydrazono derivative 3. Other prodrugs as sulfacetamide-pyrazoles, 5a, 5b and 5c were furnished via cyclocondensation of 3 with aryl/heteroaryl hydrazines. X-ray diffraction for single crystal was used to confirm the molecular and supramolecular structures of 3. In addition, DFT studies were performed to analyze the geometric parameters and compute the electronic properties of 3 and 5a-c. Hirshfeld analy…
MICELLAR CHROMATOGRAPHIC PROCEDURE WITH DIRECT INJECTION FOR THE DETERMINATION OF SULFONAMIDES IN MILK AND HONEY SAMPLES
2001
The capability of liquid chromatography with micellar mobile phases of sodium dodecyl sulfate (SDS), of allowing the direct injection of biological fluids into reversed-phase columns, was applied to the determination of sulfonamides in milk and honey samples. The chromatographic behavior of a group of 15 sulfonamides was studied at pH 3.0 where the drugs showed a greater separation space. Acetonitrile was added to the mobile phase to decrease the retention of the most hydrophobic drugs and increase the efficiencies, which yielded a higher resolution. The samples were diluted with 0.10 M SDS to facilitate the solubilization of the matrix compounds and release the protein-bound drugs. The pro…
