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.

Methylguanidine (MG) is a guanidine compound deriving from protein catabolism. It is also a product of putrefaction. Methylguanidine is a suspected uraemic toxin that accumulates in renal failure, however it also exhibits anti-inflammatory effects. Methyl

3-Hydroxybutyric acid (Butanoic acid) (or beta-hydroxybutyrate) is a ketone body. Like the other ketone bodies (acetoacetate and acetone), levels of 3-hydroxybutyrate in blood and urine are raised in ketosis. In humans, 3-hydroxybutyrate is synthesized in the liver from acetyl-CoA and can be used as an energy source by the brain when blood glucose is low. Blood levels of 3-hydroxybutyric acid levels may be monitored in diabetic patients to look for diabetic ketoacidosis. Persistent mild hyperketonemia is a common finding in newborns. Ketone bodies serve as an indispensable source of energy for extrahepatic tissues, especially the brain and lung of developing mammals. Another important function of ketone bodies is to provide acetoacetyl-CoA and acetyl-CoA for the synthesis of cholesterol, fatty acids, and complex lipids. During the early postnatal period, acetoacetate (AcAc) and beta-hydroxybutyrate are preferred over glucose as substrates for synthesis of phospholipids and sphingolipids in accord with requirements for brain growth and myelination. Thus, during the first 2 weeks of postnatal development, when the accumulation of cholesterol and phospholipids accelerates, the proportion of ketone bodies incorporated into these lipids increases. On the other hand, an increased proportion of ketone bodies is utilized for cerebroside synthesis during the period of active myelination. In the lung, AcAc serves better than glucose as a precursor for the synthesis of lung phospholipids. The synthesized lipids, particularly dipalmitoylphosphatidylcholine, are incorporated into surfactant, and thus have a potential role in supplying adequate surfactant lipids to maintain lung function during the early days of life (PMID: 3884391 ). 3-Hydroxybutyric acid is found to be associated with fumarase deficiency and medium-chain acyl-CoA dehydrogenase deficiency, which are inborn errors of metabolism.

NADH disodium salt (Disodium NADH) hydrate is the reduced form of nicotinamide adenine dinucleotide (NAD) that can donate electrons in a reducing reaction, becoming oxidized to produce NAD+. Various enzymes utilize NADH disodium salt hydrate plus H+ to reduce substrates, generating NAD+ and the reduced product.

Pyrroloquinoline quinone disodium salt (Methoxatin disodium salt), an aromatic tricyclic o-quinone, is a redox cofactor for bacterial dehydrogenases. It is an efficient electron transfer catalyst from a number of organic substrates to molecular oxygen (O2), constructing quinoprotein model reactions.
