Calcium Channels

Sipatrigine, a neuroprotective agent, is a glutamate release inhibitor, voltage-dependent sodium channel and calcium channel inhibitor, penetrating the central nervous system. Has potential to treat focal cerebral ischemia and stroke.

Calcium-Sensing Receptor Antagonists I is an antagonist of calcium-sensing parathyroid hormone receptors.

NNC 55-0396, Mibefradil derivative, is a highly selective T-type calcium channel blocker; displays IC50 values of 6.8 and > 100 μM for inhibition of Cav3.1 T-type channels and HVA currents respectively in INS-1 cells.

Etripamil (MSP-2017) is a short-acting L-type calcium-channel antagonist with a rapid onset of action designed for intranasal administration, used to treat Paroxysmal Supraventricular Tachycardia (PSVT). Etripamil (MSP-2017) slows atrioventricular nodal conduction and prolongs atrioventricular nodal refractory periods by inhibiting calcium ion influx through the calcium slow channels in the atrioventricular node cells.

Cav 2.2 blocker 1 (compound 9) is a N-type calcium channel (Cav 2.2) blocker for the treatment of pain, with an IC50 of 1 nM.

CM-4620 is a calcium-release activated calcium-channel (CRAC) inhibitor, with IC50s of 119, 895 nM for Orai1/STIM1 and Orai2/STIM1 channels, respectively.

NecroX-5 is a derivative of the NecroX, reduces intracellular calcium concentration, and possesses anti-inflammatory and anti-cancer activity.
