Ajmaline (Cardiorythmine) is a class Ia anti-arrhythmic compound that is widely used for the diagnosis of Brugada syndrome and the acute treatment of atrial or ventricular tachycardia. Ajmaline inhibits cardiac Kv1.5 and Kv4.3 channels at therapeutic concentrations.

Coenzyme Q9 (Ubiquinone 9) (CoQ9) is a normal constituent of human plasma. CoQ9 in human plasma may originate as a product of incomplete CoQ10 biosynthesis or from the diet.

DL-Homocysteine thiolactone hydrochloride (DL-Homocysteinethiolactone hydrochloride) is a cysteine derivative that binds to and induces conformational changes in various plasma proteins, slowing coagulation and inducing oxidative stress. It decreases left ventricular systolic blood pressure and cardiac force and induces seizures in vivo.

1. Denudatine has effects on action potential of ventricular fibers and has inhibition on arrhythmogenic action of aconitine.

1. Delsoline (Belsoline) has hypotensive effects.2. Delsoline is not only effective in preventing ventricular fibrillation and arrythmia, but can raise the intebsity of the threthold of electrical shocks to cause ventricular fibrillation in rabbits, the antiarrythmic effect of it may be mainly attributed to itsganglionic blocking and negative cardiac inotropic effect.

1. Liensinine, a kind of isoquinoline alkaloid, can antagonize the ventricular arrhythmias.

Alismol has antihypertensive action, it decreases cardiac output, heart rate and left ventricular pressure, but it increases coronary flow, it has been used for the prevention of anginal attacks.

Liriodenine is a natural alkaloid that induces apoptosis in various cancer cells by targeting caspase-3 and caspase-9, and exhibits antimicrobial, antifungal, antitumour, antiviral, and antiplatelet aggregation activities.

N-methyltaxol C and paclitaxel can produce a positive inotropic effect in papillary muscle, without alterations in the action potential. They can induced conduction arrhythmias and reduce coronary flow and left ventricular systolic pressure in the isolate
