Synthesis of some noval qunazolinone derivatives for their anticonvulsant activity

The quinoline family comprises an appealing group of heterocyclic compounds, with quinazolinones and their synthetic analogs being of particular interest. To synthesize 3- amino 2-phenyl quinazolinones, anthranilic acid and its substituted derivatives were employed as initial materials. The MES method was utilized to evaluate the anticonvulsant activity of the developed substances on albino mice, with phenytoin serving as a benchmark anticonvulsant medication.The synthesized compounds demonstrated noteworthy anticonvulsant activity, comparable to that of established prescription medications. Among these compounds, Compound A-1 exhibited the highest level of activity. This indicates the potential of these synthetic analogs as effective anticonvulsants, with Compound A-1 standing out as particularly promising in this regard. Preliminary results indicate that certain quinazolinone derivatives exhibited promising anticonvulsant effects in the MES test. Further investigation into the mechanism of action and safety profile of these compounds is underway. The structure-activity relationships deduced from this study may guide the design of future anticonvulsant agents based on the quinazolinone scaffold.This research contributes to the ongoing efforts to discover new therapeutic options for epilepsy and provides valuable insights into the potential of quinazolinone derivatives as anticonvulsant agents. The findings underscore the importance of exploring diverse chemical structures in the quest for improved treatments for neurological disorders.
