Abstract
A novel series of quinazolinone T-type calcium channel antagonists have been prepared and evaluated using in vitro and in vivo assays. Optimization of the screening hit 3 by modifications of the 3- and 4-positions of the quinazolinone ring afforded potent and selective antagonists that displayed in vivo central nervous system efficacy in epilepsy and tremor models, as well as significant effects on rat active wake as measured by electrocorticogram.
