Abstract
A novel series 7(a–f) 3-[5-(4-substituted) phenyl-1,3,4-oxadiazole-2yl]-2 phenylquinazoline-4(3H)-ones have been synthesized and screened for its anticonvulsant and neurotoxic activity. After i.p. injection to mice at doses of 30, 100, and 300 mg/kg body weight 2,3-disubstituted-quinazolin-4(3H)-ones were examined in the maximal electroshock induced seizures (MES) and subcutaneous pentylenetetrazole (scPTZ) induced seizure models in mice. Spectroscopic data were consistent with the structure of newly synthesized compounds. The neurotoxicity was assessed using the rotorod method. In the prepared series, 7a was found to be active in the MES screen at 0.5 h, whereas 7f showed anticonvulsant activity at both 0.5 and 4 h.
