Quinine hemisulfate is an antiarrhythmic agent. Quinidine is a potent, orally active, selective cytochrome P450db inhibitor. Quinine hemisulfate is also a blocker of K + channel with an IC 50 of 19.9 μM. Quinine hemisulfate has potential to be used for malaria research [1] [2] [3].

Quinidine methiodide is a quaternized derivative of quinidine and a classical ion channel blocker. Unable to penetrate the blood-brain barrier, it prolongs action potential duration by exclusively blocking voltage-gated sodium and potassium channels on peripheral membranes, acting as a benchmark tool in neuromuscular and cardiovascular electrophysiology research.

Acebutolol is a cardioselective beta-1 adrenergic antagonist with antiarrhythmic and hypotensive activity and little effect on the bronchial receptors. Acebutolol has stabilizing and quinidine-like effects on cardiac rhythm, as well as weak inherent sympa

DA 1686 is a therapeutic antiarrhythmic compound.DA 1686 reduces the tachycardic effects of aconitine. It also reduces the effects of increased frequency of electrical stimulation and is 1.8 times more active than quinidine and 9 times more active than procainamide.

(3S)-hydroxy Quinidine is an active quinidine metabolite. Quinidine, an antiarrhythmic agent, undergoes rapid first-pass metabolism by the cytochrome P450 (CYP) isoforms CYP3A4, CYP2C9, CYP2E1, and CYP3A5, with CYP3A4 being the most active enzyme in the (3S)-hydroxy quinidine formation. (3S)-hydroxy Quinidine prolongs repolarization of canine Purkinje fibers in vitro and prevents ventricular fibrillation and ventricular tachycardia after coronary reperfusion in isolated rat hearts in a dose-dependent manner.

Ep vinyl quinidine (3-Epiquinine) is an epi-vinyl stereoisomer of Quinidine, which is used in malaria research and acts as an antiarrhythmic agent. Quinidine is a potent, orally active, selective inhibitor of cytochrome P450db and a blocker of K+ channels with an IC50 of 19.9 μM [1] [2] [3].

Quinidine Monosulfate is an antiarrhythmic agent and a potent, orally active, selective cytochrome P450db inhibitor. Additionally, it functions as a K+ channel blocker with an IC50 of 19.9 μM, and can be used for malaria research [1] [2] [3].

Quinidine is a potent, orally active, selective inhibitor of cytochrome P450db. Quinidine hydrobromide is a K + channel blocker (IC 50= 19.9 μM). Quinidine hydrobromide shows antiarrhythmic activity. Quinidine hydrobromide can be used for malaria research.

Quinidine polygalacturonate is a potent, selective, orally active inhibitor of cytochrome P450db (cytochrome P450db) and a potent K+channel blocker with an IC50 value of 19.9 μM, which also induces apoptosis. Quinidine polygalacturonate is an anti-arrhythmic agent that can also be used in malaria research.

Quinidine sulfate, an antiarrhythmic agent, is a potent, orally active, selective cytochrome P450db inhibitor and a K+ channel blocker with an IC50 of 19.9 μM. It can also be used for malaria research [1] [2] [3].

Quinidine-D3 is the deuterated form of Quinidine (TMSM-2361), an established antiarrhythmic agent and potent potassium-channel blocker with an IC50 of 19.9 μM. Quinidine-D3 retains inhibitory activity toward CYP450db and is employed in pharmacokinetic analyses, ion-channel research, and studies of antimalarial mechanisms.
