개요

2-AMINOETHANETHIOL is the chemical compound with the formula HSCH₂CH₂NH₂. It is the simplest stable aminothiol and a degradation product of the amino acid cysteine. It is often used as the hydrochloride salt, HSCH₂CH₂NH₃Cl. The comparatively high melting point of cysteamine (95-97 °C), indicates that exists in a salt form.

화학적 성질

2-AMINOETHANETHIOL is white powder

용도

antihyperlipidemic, HMGCoA reductase inhibitor

정의

2-AMINOETHANETHIOL is an amine that consists of an ethane skeleton substituted with a thiol group at C-1 and an amino group at C-2.

제조 방법

Cysteamine can also be prepared by the reaction of ethylenimine with hydrogen sulfide.
(NHCH₂CH₂) + H₂S → HSCH₂CH₂NH₂.

화학 반응

2-AMINOETHANETHIOL is used as the hydrochloride salt, as it readily oxidizes to the corresponding disulfide, in the presence of air. The amine portion of the molecule serves as a catalyst for this reaction.
4 HSCH₂CH₂NH₂ + O₂ → 2 NH₂CH₂CH₂SSCH₂CH₂NH₂ + 2 H₂O.

Pharmaceutical Applications

Under the trade name Cystagon, cysteamine is used in the treatment of disorders of cystine excretion. Cysteamine cleaves the disulfide bond with cystine to produce molecules that can escape the metabolic defect in cystinosis and cystinuria.
It is also used for treatment of radiation sickness.
Cysteamine is used in the body to form the essential biochemical coenzyme A by combining with pantothenate and adenosine triphosphate.
In 2008, Raptor Pharmaceuticals started phase II clinical trials testing a delayed release (DR) preparation of cysteamine bitartrate for Huntington's disease. DR Cysteamine is also being investigated as a treatment for cystinosis, Batten disease, and non-alcoholic steatohepatitis.

Safety Profile

Poison by intravenous, subcutaneous, and intraperitoneal routesModerately toxic by ingestion. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits very toxic fumes of SO, and NOx,.

Purification Methods

It is soluble in H2O giving an alkaline reaction, and it has a disagreeable odour. A likely impurity is the disulfide cystamine which is not soluble in alkaline solution. Under a N2 atmosphere dissolve it in EtOH, evaporate to dryness and wash the white residue with dry pet ether, then sublime it at 0.1mm and store it under N2 at 0-10o in the dark. Its HgCl2 (2:3) complex has m 181-182o (from H2O), and its picrate has m 125-126o.
