  Synthesis and biological evaluation of some new pyridazinone derivatives

  摘要：

  A series of pyridazinone derivatives (19-34) were synthesized with an aim to synthesize safer anti-inflammatory agents. The compounds were evaluated for their anti-inflammatory, analgesic, ulcerogenic and lipid peroxidation (LPO) actions. The percentage inhibition in edema at different time intervals indicated that compounds 20, 26, 28 and 34 exhibited good anti-inflammatory potential, comparable with that of ibuprofen (85.77%) within a range of 67.48-77.23%. The results illustrate that 5-(4-fluoro-benzyl)-3-(4-chloro-phenyl)-1,6-dihydro-6-pyridazinone (26) and 5-(4-chloro-benzyl)-3-(4-chloro-phenyl)-1,6-dihydro-6-pyridazinone (20) showed best anti-inflammatory activity. Furthermore, activity is more in case of chloro substitution as compared with methyl-substitution. The compounds synthesized were also evaluated for their ulcerogenic and LPO action and showed superior gastrointestinal safety profile along with reduction in LPO as compared with that of the ibuprofen.

  Two series of pyridazinone derivatives (19-34) were synthesized and evaluated for antitubercular activities against Mycobacterium tuberculosis H(37)Rv strain. The results illustrated that among the synthesized compounds, compound 25, 5-(4-hydroxy-3-methoxybenzyl)-3-(4-chloro-phenyl)-1,6-dihydro-6-pyridazinone emerged as a lead compound with good antitubercular activity. Four more compounds, (21, 22, 29 & 33) were significant in their antitubercular action.
