Adenosine is a purine nucleoside comprising a molecule of adenine attached to a ribose sugar molecule moiety via a β-N9-glycosidic bond. It plays an important role in energy transfer. It is an endogenous purine nucleoside that modulates physiological process wherein cellular signaling by…

Adenosine 5'-triphosphate (ATP) is a central component of energy storage and metabolism in vivo. ATP is used in many cellular processes, respiration, biosynthetic reactions, motility, and cell division. ATP is a substrate of many kinases involved in cell signaling and of adenylate cyclase(s)…

β-NADP is a coenzyme necessary for the alcoholic fermentation of glucose and the oxidative dehydrogenation of other substances. It occurs widely in living tissue, especially in the liver. Nicotinic acid can be converted to nicotinamide in the body and, in this form, is found as a component of…

β-NADH, a pyridine nucleotide and biologically active form of nicotinic acid, is a coenzyme necessary for the catalytic reaction of certain enzymes. β-NAD+ is a carrier for hydride ion, forming β-NADH. The hydride ion is enzymatically removed from a substrate molecule by the action…

Adenosine 5′-diphosphate is a P2Y receptor agonist. Adenosine 5′-diphosphate has been used to study the release, neuronal effects and removal of extracellular β-nicotinamide adenine dinucleotide (β-NAD+) in the rat brain. Adenosine 5′-diphosphate has also been used to…

β-NAD is one of the biologically active forms of nicotinic acid. Occurs in living cells, primarily in the oxidized state Coenzyme for dehydrogenases NAD usually acts as a hydrogen acceptor, forming NADH Major electron acceptor molecule in biological oxidations. Acts as a…

Uridine is one of the four basic components of ribonucleic acid (RNA); the other three are adenosine, guanosine, and cytidine. Upon digestion of foods containing RNA, uridine is released from RNA and is absorbed intact in the gut. Uridine plays a role in the glycolysis pathway of galactose. …

Adenosine 5'-triphosphate (ATP) disodium salt hydrate is a multifunctional nucleotide, which is essential in a variety of cellular functions. Adenosine 5′-triphosphate (ATP) is a central component of energy storage and metabolism in vivo. ATP is used in many cellular processes:…

Guanosine is a purine nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a β-N9-glycosidic bond. Guanosine can be phosphorylated to become guanosine monophosphate (GMP), cyclic guanosine monophosphate (cGMP), guanosine diphosphate (GDP), and guanosine triphosphate…

Adenosine is a nucleotide resulting from the union of one molecule of sugar -- d-ribose -- with a base -- l-adenine. Active in cardiovascular disorders Indicated in cases of angina pectoris Increases coronary output Vasodilator action Induced apoptosis in human leukemia HL-60…

P2 purinergic agonist; increases activity of Ca2+-activated K+ channels; substrate for ATP-dependent enzyme systems. Adenosine 5'-triphosphate (ATP) and its phosphate bonds are the basic components of energy exchange in many biological systems.

Cytidine is a pyrimidine nucleoside that is composed of the base cytosine linked to the five-carbon sugar d-ribose. There are a variety of cytidine analogs with potentially useful pharmacology. Cytidine when intraperitoneal administered in combination with choline improves nerve regeneration and…
