Abstract

We have synthesized and evaluated alpha,alpha'-disubstituted phenylacetate derivatives that were designed as T-type calcium channel blockers. Among them, compound 10e (IC(50)=8.17+/-0.48nM) showed the most potent T-type calcium current blocking activity and higher potency than Mibefradil (IC(50)=1.34+/-0.49microM). The PK profile and subtype selectivity over L-type calcium channel were satisfied for further animal assay using disease model.
