Synthesis and Evaluation of Some New (1,2,4) Triazolo(4,3‐a)Quinoxalin‐4(5H)‐one Derivatives as AMPA Receptor Antagonists

Abstract

This study involves the synthesis and anticonvulsant evaluation of 1‐ethyl‐3‐hydrazinylquinoxaline‐2‐(1H)‐one ( 8 ), its chemical confirmations 9 and 10 and certain (1,2,4) triazolo(4,3‐a)quinoxalin‐4(5H)‐one compounds 11 , 12 , 13 , 13a , 13b , 13c , 13d , 13e , 13f , 14 , 15 , 16 . The structure of the synthesized compounds was confirmed chemically by elemental analyses and spectral data (IR, 1 H NMR, 13 C NMR, and Mass). Docking studies were preformed to all of the synthesized compounds to predict, in a qualitative way, the anticonvulsant activity of the proposed compounds. There is a promising correlation between the results of molecular modeling and the anticonvulsant activity of the synthesized compounds. The highest fitting value was noticed for compounds 9 and 10 , which showed the highest anticonvulsant activity.
