New Bioprecursor Prodrugs of Sulfadiazine: Synthesis, X-ray Structure and Hirshfeld Analysis

Sulphonamide motif is found extensively in numerous chemotherapeutic drug candidates, it acts by stopping the production of folate inside bacterial cell. Current research has established synthesis and characterization new bioprecursor prodrugs sulfadiazine. The first prodrug, 3, was synthesized via coupling diazonium salt sulfadiazine with ethyl acetoacetate AcONa at 0 °C. second sulfadiazine-pyrazole, 5, furnished cyclocondensation hydrazono derivative, 2-pyridyl hydrazine, 4. generated data from X-ray analysis interpreted refined to obtain crystal structure target compound, 5. Density functional theory (DFT) method used calculate optimized geometrical parameters, electronic state (HOMO–LUMO), properties. Moreover, Hirshfeld revealed that most important contributions packing prodrug 5 are H···H, O···H H···C contacts.
