Synthesis and evaluation of the anticonvulsant activities of new 5-substitued-[1,2,4]triazolo[4,3-a]quinoxalin-4(5H)-one derivatives

Background: Eplilepsy is defined as one of the most common neurological diseases, which affects approximately 50 million people all over the word. Despite the development of several new antiseizure drugs, the treatment of epilepsy remains still inadequate, because generally, anticonvulsant drugs can cause serious side effects such as neurotoxicity, depression, and impaired memory function. It is therefore imperative to search for new, safer, and more effective drugs for epilepsy. Methods: All the synthesized compounds were evaluated their anticonvulsant activities by the Maximal electroshock seizure and chemical-induced seizures models. The neurotoxicity of the compounds was measured in mice by the rotarod test. Results: Twenty 5-substitued-[1,2,4]triazolo[4,3-a]quinoxalin-4(5H)-one derivatives were synthesized and evaluated for anticonvulsant activities. Compound 5d was the most potent with an ED50 value of 27.39 mg/kg and a PI of 24.99. It also protected against seizures induced by pentylenetetrazole and bicuculline. In addition, compound 5d exhibited an ED50 value of 76.1 mg/kg and a PI > 39.44 following oral administration. Conclusion: All the synthesized compounds were confirmed by IR, 1H-NMR, 13C-NMR, and Mass spectra. Compound 5-hexyl-[1,2,4]triazolo[4,3-a]quinoxalin-4(5H)-one (5d) was safer than the commercially available drugs carbamazepine by administration of i.p in MES test. It also protected against seizures induced by chemical substances. Compound 5d should be a potential oral agent for treatment of epilepsy.

NUCLEOPHILIC SUBSTITUTIONS ON 2-CHLORO-3-NITROQUINOXALINE

Piperidine, cyclohexylamine, methoxide ion and para-thiocresolate ion react with 2-chloro-3-nitroquinoxaline 1 by selectively substituting the nitro group, in contrast to be behavior of most ortho-chloronitroaromatics which loose halide when subjected to nucleophilic substitution reactions.This inversion is interpreted as being due to the lack of activation of the 2-position by the nitro group in the 3-position because of the low value of the ?-bond index between these two vertices.It is also suggested that the substitution by neutral reagents such as amines is strongly influenced by stabilizing interactions between the negatively charged nitro group and the ammonium moiety in the ? complex; this built-in solvation may be responsible for inversions in the chemoselectivity between chloro and nitro nucleofugicities.
