Upon its conversion to adenosine by ecto-ADPases, platelet activation is inhibited via adenosine receptors.

5'-Guanylic acid disodium salt (GMP-5) is a purine ribonucleoside monophosphate. L-Glutamic acid and guanosine monophosphate are biosynthesized from xanthylic acid and L-glutamine via GMP synthase [glutamine-hydrolyzing]. Guanosine triphosphate and guanosine monophosphate are biosynthesized from diguanosine tetraphosphate via bis(5'-nucleosyl)-tetraphosphatase [asymmetrical]. In humans, guanosine monophosphate is involved in the kanamycin, telithromycin, tobramycin, and erythromycin action pathways, and several metabolic disorders including AICA-ribosiduria, adenosine deaminase deficiency, adenine phosphoribosyltransferase deficiency (aprt), and 2-hydroxyglutric aciduria (D and L form) pathways. Guanosine monophosphate is also found in foods like onion-family vegetables, millet, Chinese water chestnut, and red rice, serving as a potential biomarker for the consumption of these foods.

Uridine-5'-diphosphate disodium salt (UDP disodium salt) is a specific agonist of the P2Y6 receptors (EC50 = 13 nM for human P2Y6), stimulating the production of inflammatory mediators, phagocytosis, and vasoconstriction. Uridine-5'-diphosphate disodium salt also acts as an antagonist of P2Y14.

2'-Deoxyguanosine monohydrate (Guanine-2'-deoxyriboside) is a nucleoside consisting of the base guanine and the sugar deoxyribose. It is like guanosine, but with one oxygen atom removed. It is a nucleoside component of DNA. 2'-Deoxyguanosine monohydrate can be converted to 8-hydroxy-deoxyguanosine (8-OHdG) due to hydroxyl radical attack at the C8 of guanine. 8-OHdG is a sensitive marker of the DNA damage This damage, if left unrepaired, has been proposed to contribute to mutagenicity and cancer promotion.

2'-Deoxycytidine is one of the major nucleosides of DNA consisting of cytosine and deoxyribose and inhibits the biological effects of bromodeoxyuridine (Brdu). The nucleoside consists only of a pentose sugar attached to a purine or pyrimidine base and has no phosphate group.

Deoxyadenosine monophosphate is a derivative of the common nucleic acid ATP, or adenosine triphosphate, in which the -OH (hydroxyl) group on the 2' carbon on the nucleotide's pentose has been removed (hence the deoxy- part of the name). Additionally, the monophosphate of the name indicates that two of the phosphoryl groups of GTP have been removed, most likely by hydrolysis. Deoxyadenosine monophosphate is abbreviated dAMP.
