Prodrugs of sulfacetamide: Synthesis, X-ray structure, Hirshfeld analysis, antibacterial assessment, and docking studies

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…
