A potent calcium channel blockader with marked vasodilator action. It has antihypertensive properties and is effective in the treatment of angina and coronary spasms without showing cardiodepressant effects. It has also been used in the treatment of asthma an…
3-Carbamoyl-1-beta-D-ribofuranosyl pyridinium hydroxide-5'phosphate, inner salt. A nucleotide in which the nitrogenous base, nicotinamide, is in beta-N-glycosidic linkage with the C-1 position of D-ribose. Synonyms: Nicotinamide Ribonucleotide; NMN. [PubC…
A direct-acting peripheral vasodilator that causes flushing and may decrease blood pressure. It is used in vasospasm and threatened gangrene. [PubChem]
A beta-adrenergic agonist used in the treatment of asthma and bronchospasms. [PubChem]
A strong dicarboxylic acid occurring in many plants and vegetables. It is produced in the body by metabolism of glyoxylic acid or ascorbic acid. It is not metabolized but excreted in the urine. It is used as an analytical reagent and general reducing agent. […
Amino-substituted glyoxylic acid derivative. [PubChem]
A quaternary ammonium anticholinergic agent with peripheral side effects similar to those of atropine. It is used as an adjunct in the treatment of gastric and duodenal ulcer, and to relieve visceral spasms. The drug has also been used in the form of eye drop…
An oligosaccharide antibiotic produced by various streptomyces. [PubChem]
5'-Adenylic acid, monoanhydride with imidodiphosphoric acid. An analog of ATP, in which the oxygen atom bridging the beta to the gamma phosphate is replaced by a nitrogen atom. It is a potent competitive inhibitor of soluble and membrane-bound mitochondri…
A simple organophosphorus compound that inhibits DNA polymerase, especially in viruses and is used as an antiviral agent. [PubChem]
The phosphoric acid ester of threonine. Used as an identifier in the analysis of peptides, proteins, and enzymes. [PubChem]
An amino acid that occurs in endogenous proteins. Tyrosine phosphorylation and dephosphorylation plays a role in cellular signal transduction and possibly in cell growth control and carcinogenesis. [PubChem]
A noncompetitive antagonist at GABA-A receptors and thus a convulsant. Picrotoxin blocks the gamma-aminobutyric acid-activated chloride ionophore. Although it is most often used as a research tool, it has been used as a CNS stimulant and an antidote in poison…
