Calcium channel is an ion channel which displays selective permeability to calcium ions. It is sometimes synonymous as voltage-dependent calcium channel, although there are also ligand-gated calcium channels. Voltage-gated calcium (CaV) channels catalyse rapid, highly selective influx of Ca2+ into cells despite a 70-fold higher extracellular concentration of Na+. Some calcium channel blockers have the added benefit of slowing your heart rate, which can further reduce blood pressure, relieve chest pain (angina) and control an irregular heartbeat.

Synta-66 |
835904-51-3 | Synta-66 is a potent, selective CRAC channel Orai1 blocker with IC50 of 3 uM; does not impair other plasma membrane ion transporters; inhibits antigen-evoked Ca2+ influx in Fura-2-loaded cells at 10 uM, prevents the increase in Syk activity triggered by Ca2+ entry; reduces FcεRI-dependent Ca(2+) influx and the release of histamine, leukotriene C4, and cytokines (IL-5/-8/-13 and TNFα) by up to 50% at 3 uM in HLMCs. |
GY10142 |
BTT-266 |
BTT-266 (BTT266) is a voltage-gated CaV2.2 calcium channel inhibitor that disrupts the CaVα·CaVβ3 protein-protein interaction, directly binds to CaVβ3 with Kd of 3.6 uM; decreases surface presentation of the CaV2.2α1 subunit, significantly reduces trafficking of CaV2.2 to the plasma membrane at 50 uM, does not affect CaV2.2 currents in either in HEK-CaV2.2 cells or rat dorsal root ganglion (DRG) neurons. |

GY10143 |
BTT-369 |
BTT-369 (BTT369) is a voltage-gated CaV2.2 calcium channel inhibitor that disrupts the CaVα·CaVβ3 protein-protein interaction with Ki of 2.0 uM in FP assays; decreases trafficking of CaV2.2 channels to the plasma membrane and modulates the functions of the channel, suppresses pain responses in rodent neuropathic pain models; BTT-369 (BTT369) is a cell-permeable derivative of BTT-266. |

SAK3 |
1256269-87-0 | SAK3 (T-VGCC enhancer SAK3) is a potent, orally acitve enhancer of T-type voltage-gated Ca2+ channel (T-VGCC), enhances CaV3.1 and CaV3.3, but not CaV3.2 activity at concentrations of 0.01-10 nM in neuro2A cells in vitro; significantly enhanced acetylcholine (ACh) release in the hippocampal CA1 region of na?ve mice (0.5 mg/kg, p.o.); significantly enhanced hippocampal ACh levels in olfactory-bulbectomized (OBX) mice, rescuing impaired memory-related behaviors. |
GY05238 |
RU1968 |
171336-24-6 | RU1968 is a potent, cross-species sperm-specific Ca2+ channel CatSper inhibitor that is selective for CatSper over Slo3; suppresses progesterone- and prostaglandin-induced Ca2+ signals in human sperm (IC50=4 and 3.8 uM), potently abolishes CatSper-mediated Ca2+ signals in mouse, human, and sea urchin sperm. |
GY05225 |
ACT 709478 |
1838651-58-3 | ACT 709478 is a potent, selective, orally-bioavailable, brain penetrant T-type calcium channel blocker with IC50 of 6.4, 18, and 7.5 nM for Cav3.1, Cav3.2, and Cav3.3 channels respectively; displays >100-fold selectivity over Cav1.2 channels; shows a significant decrease of the seizure severity in vivo (100 mg/kg, p.o.). |
GY05219 |
JTV-519 fumarate |
1883549-36-7 | JTV-519 (K201) is a Ca2+-dependent blocker of SERCA and a partial agonist of ryanodine receptors (RyRs); displays Ca(2+)-dependent inhibition of SERCA-dependent ATPase activity with IC50 of 9 uM at 0.25 Ca2+ in cardiac muscle; may prevent abnormal Ca(2+) leak from the sarcoplasmic reticulum (SR) in the ischemic heart and skeletal muscle (SkM) by stabilizing the ryanodine receptors (RyRs; RyR1 and RyR2, respectively). |
GY05374 |
JTV-519 HCl |
1038410-88-6 | JTV-519 (K201) is a Ca2+-dependent blocker of SERCA and a partial agonist of ryanodine receptors (RyRs); displays Ca(2+)-dependent inhibition of SERCA-dependent ATPase activity with IC50 of 9 uM at 0.25 Ca2+ in cardiac muscle; may prevent abnormal Ca(2+) leak from the sarcoplasmic reticulum (SR) in the ischemic heart and skeletal muscle (SkM) by stabilizing the ryanodine receptors (RyRs; RyR1 and RyR2, respectively). |
