A series of 7-(substituted phenoxyl)-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinolines and 7-(substi- tuted phenoxyl)-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinoline-1(2H)-ones were synthesized. The convulsant effect and neurotoxicity of the compound were determined with maximal electroshock test (MES), pentylenetetrazol (PTZ) method and rotarod test intraperitoneally in mice. 7-(4-Fluorophenyloxy)-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinoline-1(2H)-one (4c) was the most active and also has the lowest toxicity. In the anti-MES potency test, 4c showed a medial effective dose (ED50) of 6.8 mg/kg, a medial toxicity dose (TD50) of 88.0 mg/kg, and the protective index (PI) of 12.9. The PI value of compound 4c was better than that of the marketed drug phenytoin.

Key words: quinoline, [1,2,4]triazolo[4,3-a]quinoline, anticonvulsant, synthesis, triazole
