Abstract | The therapeutic agents flunarizine and lomerizine exhibit inhibitory activities against a variety of ion channels and neurotransmitter receptors. We have optimized their scaffolds to obtain more selective N-type calcium channel blockers. During this optimization, we discovered NP118809 and NP078585, two potent N-type calcium channel blockers which have good selectivity over L-type calcium channels. Upon intraperitoneal administration both compounds exhibit analgesic activity in a rodent model of inflammatory pain. NP118809 further exhibits a number of favorable preclinical characteristics as they relate to overall pharmacokinetics and minimal off-target activity including the hERG potassium channel.
