Cilnidipine is a 1,4-dihydropyridine derived L/N-type calcium channel dual blocker possessing neuroprotective and analgesic effects which are related to its N-type calcium channel inhibitory activity. In order to find specific N-type calcium channel blockers with the least effects on cardiovascular system, we performed structure-activity relationship study on APJ2708, which is a derivative of cilnidipine, and found a promising N-type calcium channel blocker 21b possessing analgesic effect in vivo with a 1600-fold lower activity against L-type calcium channels than that of cilnidipine.
