DL-Homocystine Chemical Properties,Usage,Production

Chemical Properties

white to slightly beige solid

Uses

DL-Homocystine is used in the synthesis of potential antitumor agents through inhibition of L-asparagine. There is growing clinical evidence that elevated homocysteine levels are associated with an increased risk of venous and arterial thrombosis.

Definition

ChEBI: Homocystine is an organic disulfide obtained by oxidative dimerisation of homocysteine. It has a role as a human metabolite. It is a tautomer of a homocystine zwitterion.

Purification Methods

dl-Homocystine crystallises in platelets from water with 1H2O and m 258-260o(dec), all operations should be carried out under N2. [Sudo J Chem Soc Jpn (Pure Chem Sect) 79 81, 86, 87 1958, Beilstein 4 IV 3199.]
