IC50: 36 nM (VSCC)[1]

PD173212 (PD 173212, 300 nM) potently blocks recombinant B-class (N-type) calcium channel currents 78±7.8%, with an IC50 of 74 nM, by whole-cell voltage-clamp techniques. PD 173212 possesses selectivity for non L-type Ca2+ channels versus neuronal Na+, K+, and L-type Ca2+ channels[1].

PD173212 (30 mg/kg, i.v.) shows moderate efficacy in preventing tonic seizures in the audiogenic seizure model[1].
