Bioorg Med Chem Lett. 2013 Mar 15;23(6):1887-90. doi: 10.1016/j.bmcl.2012.12.072. Epub 2013 Jan 12.

Abstract

To obtain selective and potent inhibitor for T-type calcium channel by ligand based drug design, 2-hydroxy-3-phenoxypropyl piperazine derivatives were synthesized and evaluated for in vitro activities. Compound 6m and 6q showed high selectivity over hERG channel (IC50 ratio of hERG/α1G6m=8.5, 6q=18.38) and they were subjected to measure pharmacokinetics profiles. Among them compound 6m showed an excellent pharmacokinetic profile in rats.
