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.

  • HY-B0280R
    Ranolazine (Standard)
    		Inhibitor
    Ranolazine (Standard) is the analytical standard of Ranolazine. This product is intended for research and analytical applications. Ranolazine (CVT 303) is an anti-angina drug that achieves its effects by inhibiting the late phase of inward sodium current (INa and IKr with IC50 values of 6 μM and 12 μM, respectively) without affecting heart rate or blood pressure (BP). Ranolazine is also a partial fatty acid oxidation (FAO) inhibitor. Antianginal agent.

    Sadopine
    		Modulator
    Sadopine is an allosteric modulator for dihydropyridine receptor ((-)Sadopine as positive allosteric modulator and (+)Sadopine as negative allosteric modulator). Sadopine interacts with dihydropyridine (DHP)-sensitive L-type calcium channels.

    1,4-Dihydropyridine
    		Inhibitor
    1,4-Dihydropyridine is an inhibitor for calcium channel, that blocks the L-type calcium channels, reduces the influx of calcium ions into cardiac and vascular smooth muscle cells, and thus reduces the contractility and heart rate of the heart, dilates blood vessels, and lowers blood pressure.

    PDDHV
    		Activator
    PDDHV is a calcium absorption inducer and may achieve 45Ca2+ influx by stimulating vanillic acid receptor VR1.
