SYNTHESIS, IN‐SILICO BIOCHEMICAL PROPERTIES, AND IN‐VITRO ANTIMICROBIAL ACTIVITY OF SOME FARMAZANS DERIVATIVES CONTAINING SULFONAMIDE MOIETY

The low effectiveness of currently available antibiotics is driving efforts worldwide to create new antimicrobial medicines. We made several novel formazan chemicals, including sulfonamides, and assessed how well they may work against bacteria. Consequently, attempts were undertaken to combine the moieties of formazan and sulfonamide to produce new derivatives or more effective antibacterial drugs. Condensing sulphanilamide with benzaldehydes in the presence of glacial acetic acid and ethanol produced a Schiff base of sulphonamide, which when combined with substituted benzene diazonium chlorides (2a–g) during condensation yields formazan derivatives (3a–g). Based on analytical and spectral data (IR, 1HNMR, and mass), the structures of all the synthesized compounds were described, and they agree well with the suggested ones. Using Ciprofloxacin and Ketoconazole as reference medications, the Agar diffusion method was utilized to assess the antibacterial activity of the synthesized compounds by measuring the zone of inhibition against harmful strains of bacteria and fungi. In contrast to the norm, every molecule examined has demonstrated a notable level of antibacterial activity.
