  Design, synthesis, and evaluation of anti-inflammatory and ulcerogenicity of novel pyridazinone derivatives

  摘要：

  A series of pyridazinone-containing compounds were designed and synthesized as congeners for diclofenac, the most potent and widely used NSAID. The target compounds were evaluated for their anti-inflammatory activity on rat paw edema inflammation model against diclofenac as a reference compound. Seven of the tested compounds demonstrated more than 50% inhibition of carrageenan-induced rat paw edema at a dose 10 mg/kg. The compounds, 6-(2-bromophenylamino)pyridazin-3(2H)-one 2a and 6-(2,6-dimethylphenylamino)pyridazin-3(2H)-one 2e, displayed 74 and 73.5% inflammation-inhibitory activity, respectively, which is comparable to diclofenac (78.3%) at the same dose level after 4 h. The most active compounds as anti-inflammatory agents, 2a, 2e, and 6a, displayed fewer number of ulcers and milder ulcer score than indomethacin in ulcerogenicity screening.

  A series of novel substituted 3,6-disubstituted pyridazines based on the structure of vatalanib (PTK787) were designed and synthesized. The cytotoxicity of the final compounds was tested in vitro on HT-29 colon cancer cell line. Compounds 2a and 2b with 4-chlorophenylamino moiety, exerted the highest cytotoxic activity with IC50 values equal to 15.3 and 3.9 μM respectively. The most promising compound, 2b, was found to be about fivefold more active than vatalanib against HT-29 colon cancer cell line.
