A series of nicotinic acid derivatives structurally related to niflumic acid and certain pyridazine-containing compounds have been synthesized and characterized by analytical and spectral data. All compounds were screened for their potential analgesic and anti-inflammatory activities. The compounds which displayed analgesic and anti-inflammatory activities were tested for ulcerogenicity and screened for in vivo inhibition of certain inflammatory cytokines such as tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and cyclooxygenase-2 (COX-2). Compounds 1c, 2a, 2b, and 5a have shown potent analgesic and anti-inflammatory activities.
evaluated for their analgesic and anti-inflammatory activities. Compounds including 2-bromophenyl substituent, 4a, c, and d, proved to display distinctive analgesic and anti-inflammatory activities in comparison to mefenamic acid as a reference drug. Compound 4c could be identified as the most biologically active member within this study with an interesting dual anti-inflammatory analgesic profile. Effect
