Nicofuranose is a niacin derivative used as a hypolipidemic agent. The Nicofuranose administration leads to inhibition of free fatty acid turnover and consequently a marked reduction in triglyceride turnover. Nicofuranose, unlike clofibrate, did not affect the mechanisms responsible for the clearance of plasma triglycerides.

Proscillaridin is a substance that was used in Europe for the treatment of heart failure and atrial fibrillation. Proscillaridin belongs to glycosides and acts as a Na /K -ATPase inhibitor.

Hexobendine (Ustimon or ST7090) is a vasodilator. It inhibits uptake of adenosine and cAMP. Hexobendine was investigated in clinical trials for the treatment of cerebrovascular and coronary artery diseases.

ACTISOMIDE is a class 1A/1B antiarrhythmic agent. It blocks sodium channels in a manner similar to lidocaine and mexiletine. It is a well-tolerated, effective agent against both atrial and ventricular arrhythmias.

Capobenic acid is an antiarrythmetic agent, vasodilator, antianginal used for the treatment of cardiac infarction.

Nicorandil is a derivative of the niacinamide that is structurally combined with an organic nitrate. It provides a dual mode of action leading to relaxation of vascular smooth muscle. Nicorandil is a potassium-channel opener that causes vasodilatation of arterioles and large coronary arteries. Its nitrate-like properties produce venous vasodilation through stimulation of guanylate cyclase. Nicorandil has a direct effect on coronary arteries without leading to a steal phenomenon. The overall action improves blood flow to post-stenotic regions and the oxygen balance in the myocardium.

Ajmaline, (also known by trade names Gilurytmal, Ritmos, and Aritmina) is an alkaloid found in the root of Rauwolfia serpentina, among other plant sources. It is a class Ia antiarrhythmic agent that apparently acts by changing the shape and threshold of cardiac action potentials. The class I antiarrhythmic agents interfere with the sodium channel. A class IA agent lengthens the action potential (right shift) which brings about improvement in abnormal heart rhythms. This drug in particular has a high affinity for the Nav 1.5 sodium channel. Ajmaline produces potent sodium channel blocking effects and a very short half-life which makes it a very useful drug for acute intravenous treatments. The drug has been very popular in some countries for the treatment of atrial fibrillation in patients with the Wolff–Parkinson–White syndrome and in well tolerated monomorphic ventricular tachycardias. It has also been used for many years as a drug to challenge the conduction system of the heart in cases of bundle branch block and syncope. In these cases, abnormal prolongation of the HV interval has been taken as a proof for infrahisian conduction defects tributary for permanent pacemaker implantation. Ajmaline is used as an antiarrhythmic agent.

Erythrityl Tetranitrate is a vasodilator indicated for the prevention of angina. Sold under the brand name Cardilate, Erythrityl Tetranitrate is used for the prophylaxis and long-term treatment of patients with frequent or recurrent anginal pain or coronary insufficiency and during the postcoronary convalescent period to hasten recovery. Similar to other nitrites and organic nitrates, erythrityl tetranitrate is converted to an active intermediate compound which activates the enzyme guanylate cyclase. This stimulates the synthesis of cyclic guanosine 3',5'-monophosphate (cGMP) which then activates a series of protein kinase-dependent phosphorylations in the smooth muscle cells, eventually resulting in the dephosphorylation of the myosin light chain of the smooth muscle fiber. The subsequent release of calcium ions results in the relaxation of the smooth muscle cells and vasodilation. Erythrityl Tetranitrate is a is an atrial natriuretic peptide receptor agonist. Erythrityl tetranitrate is a physiologically effective long-acting agent in patients with coronary heart disease.

Istaroxime is a novel intravenous agent with luso-inotropic properties that acts by inhibition of Na( )/K( ) adenosine triphosphatase and stimulation of sarco/ endoplasmic reticulum calcium ATPase isoform 2. It is significantly decreased left ventricular end-diastolic pressure, pulmonary capillary wedge pressure, heart rate and increased systolic blood pressure and cardiac index with no change in neurohormones, renal function or troponin I. Istaroxime has successfully concluded phase II clinical trials in cardiac failure patients. Istaroxime induced apoptosis, affected the key proliferative and apoptotic mediators c-Myc and caspase-3 and modified actin cytoskeleton dynamics and RhoA activity in prostate cancer cells – this provides novel insights into the anti-cancer properties of istaroxime further supporting the development of this agent as a novel anti-cancer drug candidate.
