Biological Activity for ABT 639

ABT 639 is a CaV3.2 channel blocker (IC50 = 2.3 μM). Also blocks low voltage-activated (CaV3.1) currents in native rat DRG neurons (IC50 = 7.6 μM). Exhibits little or no activity at other ion channels and receptors. Displays antinociceptive effects in a mechanical hyperalgesia model in vivo. Orally bioavailable.
