Schiff Bases From 4-Aminoantipyrine: Investigation of Their In Silico, Antimicrobial, and Anticancer Effects and Their Use in Glucose Biosensor Design.

Five new Schiff bases from 4-aminoantipyrine were synthesized, characterized, and evaluated for their antimicrobial and DNA cleavage activities, and drug similarity properties and cytotoxicity prediction using in silico analysis. All Schiff bases had good antibacterial and antifungal activities. All compounds showed self-activating DNA cleavage ability in the absence of any reductant or oxidant at low concentrations. Modified carbon paste electrodes were prepared with all Schiff bases, and a glucose biosensor was designed. Schiff base coded (4AA-Fc) was found to have the best sensitivity to HO. It was observed that the prepared biosensor has a working range at low concentrations (1.0 × 10-1.0 × 10 M (  = 1.0)) and a low detection limit (1.0 × 10 M). At the same time, 4AA-Fc was found to be a potent compound for bactericidal and fungicidal effect, killing pathogens. Thus, it could be used for the development of a resistant biosensor in external environment. It also showed a complete DNA degradation. In silico ADME analysis and cell line cytotoxicity studies found these new Schiff bases to have favorable drug-like properties, indicating potential for the development of therapeutic drugs. In particular, the compounds were not a P-gp substrate. Thus, they could be a potential anticancer agent. The present study may be useful for further scientific research in the field of the design, synthesis, and biological studies of bioactive substances.
