Abstract
A series of new hybrid benzothiazole containing pyridazinones derivatives were designed and synthesized fulfilling all the pharmacophoric requirements essential for the anticonvulsant activity. In-silico and in vitro studies revealed that some of these hybrid derivatives demonstrated admirable GABA AT inhibitory activity. An attempt has also been made to validate the results of in vitro GABA AT inhibition of the most potent compound SPS-5F (IC50 9.10 mu M) through in vivo anticonvulsant screening. Compound SPS-5F administration significantly increases the whole brain GABA level, might be through the inhibition of GABA AT enzyme. (C) 2018 Published by Elsevier Inc.
