Abstract

T-type calcium channel is one of therapeutic targets for the treatment of cardiovascular diseases and neuropathic pain. In this study, as a part of our ongoing efforts to develop potent T-type calcium channel blockers, we designed oxazole derivatives substituted with arylpiperazinylalkylamines. The oxazoles were synthesized in a convenient convergent synthetic method, and biologically evaluated against alpha(1G) (Ca(V)3.1) T-type calcium channel. Among total 41 oxazole compounds synthesized, the most active one was the compound 10-35 with an IC(50) value of 0.65 microM, which is comparable with that of mibefradil.
