Abstract:


Chemical modification of pyridazinone may lead to a potent therapeutic agent. In this study, biological properties of pyridazinone derivatives were evaluated by assessing their antimicrobial and in-vitro antioxidant activities. The reaction of a mucochloric acid and 3-chloro-phenylhydrazine hydrochloride led to the formation of 5-aryl-4-chloro-2-(3-chloro-phenyl)-2H-pyridazin-3-one derivatives 2(a-j). The target compounds were synthesized using nucleophilic substitution reaction. In-silico molecular docking studies of the synthesized compounds were carried out with the help of V-Life Science MDS 4.6 software using GRIP batch docking method to find out which derivative had a better docking. The newly synthesized compounds were characterized by FTIR, 1HNMR, 13C-NMR, MS, and elemental analysis. Antimicrobial and in-vitro antioxidant activity study of the novel synthesized compounds were screened. Compounds 2f and 2g showed good antimicrobial having an MIC 12.5 μg/mL against Staphylococcus aureus and Candida albicans and in-vitro antioxidant activities having an IC50 50.84. The experimental results were further supported by molecular docking analysis with better interaction patterns.
