SDZ-WAG-994 is a potent and selective A1 receptor agonist, discovered by Sandoz. SDZ-WAG-994 was able to induce a dose-related and sustained fall in blood pressure and heart rate in spontaneously hypertensive rats. The compound was investigated in patients with heart failure symptoms and moderate left ventricular systolic dysfunction, where it produced no effect. In patients with patients with permanent atrial fibrillation, SDZ-WAG-994 was able to limit the increase in mean heart rate during exercise. The compound was also tested for treatment of postoperative dental pain, but for all efficacy measures, SDZ-WAG-994 was not significantly different from placebo.

3-Deaza-adenosine (BW 91Y) is a potent inhibitor of adenosine deaminase and S-Adenosylhomocysteine (SAH) hydrolase, with potent antitumor activity against a range of leukemia cell lines. 3-Deaza-adenosine has anti-inflammatory properties, inhibiting leukocyte adhesion and chemotaxis, lymphocyte-mediated cytolysis, phagocytosis, degranulation, and NF-κB signaling. 3-Deaza-adenosine also has antiviral and antibacterial activities. 3-Deaza-adenosine has previously been shown to inhibit a variety of cellular functions, which could be critical for the development of atherosclerosis and restenosis. These include the thrombin-stimulated production of platelet-derived growth factor and the expression of endothelial leukocyte adhesion molecule-1 as well as cellular arachidonic acid and ROS production. Moreover, c3Ado prevents tumor necrosis factor (TNF)-alpha production, reduces TNF- alpha-induced macrophage adhesion to endothelial cells in vitro via the inhibition of ICAM-1 synthesis, and promotes monocyte apoptosis.

Adenosine monophosphate (AMP) is a nucleotide, consisting of a phosphate group, the sugar ribose, and the nucleobase adenine. AMP is an activator of several enzymes in the tissues. In the glycolytic pathway, the enzyme phosphofructokinase is inhibited by ATP but the inhibition is reversed by AMP, the deciding factor for the reaction being the ratio between ATP and AMP. In medicine, AMP is used mainly as an alternative to adenosine for treatment of ischemia and as a tool compound to measure hyperresponsiveness of airways.

2′-Deoxyadenosine, a pair of deoxythymidine (T) in double-stranded DNA, is a substrate of adenosine deaminase. In case of absence of this enzyme, 2′-deoxyadenosine accumulates in T lymphocytes and kills these cells resulting in a genetic disorder known as adenosine deaminase severe combined immunodeficiency disease (ADA-SCID).

α,β-methylene adenosine 5′-diphosphate (AOPCP, adenosine-5′-O-[(phosphonomethyl)phosphonic acid] or α,β-methylene-ADP) is an analog of adenosine 5′-diphosphate (ADP). It acts as a CD73/ecto-5′-nucleotidase inhibitor. Blocks ecto-5'-nucleotidase-mediated adenosine production by preventing the conversion of AMP to adenosine.

Cordycepin, or 3'-deoxyadenosine, is a derivative of the nucleoside adenosine, differing from the latter by the absence of the hydroxy group in the 3' position of its ribose part. Cytostatic effect of cordycepin is due to incorporation of phospho-cordycepin into mRNA and inhibition of mRNA synthesis. Cordycepin exhibit rapid antidepressant effect due to potentiation of AMPA receptors

Nicotinamide adenine nucleotide (NAD) is a cofactor found in all living cells. It exists in oxidized form (NAD+) and reduced form (NADH). NADH is found widely in nature and is involved in numerous enzymatic reactions in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH). NADH supplements are used for improving mental clarity, alertness, concentration, and memory; as well as for treating Alzheimer’s disease and dementia. Because of its role in energy production, NADH is also used for improving athletic performance and treating chronic fatigue syndrome (CFS). Some people use NADH for treating high blood pressure, high cholesterol, jet lag, depression, and Parkinson’s disease; opposing alcohol’s effects on the liver; reducing signs of aging; protecting against the side effects of an AIDS drug called zidovudine (AZT).

Flavin adenine dinucleotide is a coenzyme form of vitamin B2. Many oxidoreductases, called flavoenzymes or flavoproteins, require FAD as a prosthetic group, which functions in electron transfers. It is usually used for the prevention and treatment of various diseases that are caused by Vitamin B2 deficiency or metabolic disorder including stomatitis, eczema, etc. No adverse reactions were reported.
