NNC 55-0396 is a highly selective T-type calcium channel blocker with an IC50 value of 6.8 μM for Cav3.1 T-type channels. NNC 55-0396 can be used for the research of neurological disease research[1][2].
NNC 55-0396 (0.1-1000 μM) shows no inhibition to the HVA Ca2+ currents in INS-1 cells[1].
NNC 55-0396 (1-100 μM) blocks more than 50% of the T-type Ca2+ current at 8 μM in HEK 293/α1G cells[1].
NNC 55-0396 blocks T-type Ca2+ current with an IC50 value of 6.8 μM[1].
NNC 55-0396 (20 mg/kg; i.p. once) suppresses tremor in GABAA subunit α1-null mice and harmaline mouse models[1].
