Abstract:
Objectives: The aim of the present study is to carry out a simple synthesis of aminoantipyrine
analogues and exploration of their antibacterial, cytotoxic, and anticonvulsant potential.
Methods: The compounds were characterized employing multi-spectroscopic methods. The in vitro
pharmacological response of a series of bacteria was screened employing serial dilution method.
The derivatives were screened against maximal electro-shock for their anticonvulsant activity. Molecular
docking was carried out to optimize the interaction of the compounds with HPV16-E7 receptors.
Further, the in vitro cytotoxicity was tested against human cervical cancer (SiHa) cell lines.
Results: The compounds show protection against maximal electroshock, esp. 3-nirto- and 4-
methyl-3-nitrobenzamido derivatives. In addition, they reveal appreciable DNA cleavage activities
and interactions with HPV16-E7 protein receptors, esp. 3,5-dinitro- and 4-methyl-3-nitrobenzamido
derivatives. Furthermore, they show potent activity against cervical cancer cells (LD50 value up to
1200 in the case of 4-methyl-3-nitrobenzamido derivative and an inhibition of a maximum of
~97% of cells).
Conclusion: The simply synthesized aminoantipyrine derivatives show a variety of biological activities
like antibacterial and anticancer effects. In addition, this is the first study demonstrating that
4-aminoantipyrine derivatives show an anticonvulsant activity.
