heterocyclic ring 1-14 were synthesized as compounds with interesting pharmacological profiles. All were investigated in vitro for their antioxidant activity. Some compounds showed significant effect in the above assay. The most promising was a group of pyrazolone. The effect was dependent mainly on the substituent on the amide group. It was found that compounds 8 and 10 showed the highest antioxidant capacity
properties have been evaluated using ADMET analysis. The cytotoxicactivity of both compounds was determined using the MTT assay on the A549cellline in comparison with etoposide. It was determined that compound 2 was effective in the inhibition of humanlung adenocarcinoma cell growth and may be a promising compound for the treatment of lung cancer.
The structure and tautomerism of N-(1-naphthyl)-3-amino-5-oxo-4-phenyl-1H-pyrazole-1-carboxamide with
antibacterial activity have been investigated with experimental approaches (X-ray studies, IR, 1H and 13C NMR spectra,
including NOESY and N-HSQC spectra) and quantum chemical calculations. It is found that the tautomer with the keto
group in position 5 is energetically privileged in the crystalline state while in DMSO and water solution the equilibrium is
shifted towards the form with the hydroxyl group at this position. These findings are related to antibacterial activity of the
studied compound and are crucial for future molecular docking and structure-activity relationship studies.
