Cystamine dihydrochloride Usage And Synthesis
Chemical Properties white powder
Uses hepatoprotectant, t-glutaminase inhibitor, heat shock protein promoter, caspase inhibitor
Uses sulfhydryl modifying reagent and heparin antagonist
Safety Profile A poison by subcutaneous and intraperitoneal routes. Experimental reproductive effects. When heated to decomposition it emits very toxic fumes of HCl, SOx, and NOx. See also SULFIDES.
Purification Methods Recrystallise the salt by dissolving in EtOH containing a few drops of dry EtOH/HCl, filtering and adding dry Et2O. The solid is dried in a vacuum and stored in a dry and dark atmosphere. It has been recrystallised from EtOH (solubility: 1g in 60mL of boiling EtOH) or MeOH (plates).
