Twelve Schiff bases of benzoxazole were prepared by usage of methyl-3-amino-4hydroxybenzoate. The chemistry of the prepared molecules was established based on the spectral data and tested for anticonvulsant activity using maximal electroshock (MES) induced seizure and subcutaneous pentylenetetrazole (scPTZ). In addition, a rotarod method to detect minimal neurological impairment in mice. In anti-MES test molecules 3d, 3e, 3i, 3j and 3k presented effective action corresponding to hydrophobicity. Other compounds of the series like 3b, 3c, 3g and 3l were remarkably less lipophilic and have some potencies. Compounds 3d and 3j effectively passed the rotarod trial without any mark of CNS deficit. In conclusion, the synthesized compounds with distal aryl groups showed higher hydrophobicity and resulted in better pharmacological action, which can be the future of new promising anticonvulsant drugs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
