Cyclothiomethylation of aliphatic polyamines with formaldehyde and hydrogen sulfide
摘要:
Cyclothiomethylation of the terminal amino groups in N-(2-aminoethyl)ethane-1,2-diamine, N,N'-bis(2-aminoethyl)ethane-1,2-diamine, and N,N'-bis(2-aminoethyl)ethane-1,1-diamine with formaldehyde and hydrogen sulfide gave the corresponding bis-1,3,5-dithiazinane derivatives. The reaction in aqueous butanol at 0 degrees C was accompanied by intermolecular thiomethylation at the secondary amino groups with formation of previously unknown polyheterocyclic compounds containing nitrogen and sulfur atoms.

Methods of ischemic tissue repair and regeneration through promoting tissue redistribution and reuse of copper by administering a composition comprising a copper chelating tetramine, such as trientine. Methods and compositions for increasing intracellular copper lever and/or inducing repair of an ischemic tissue in an individual. Increased copper level in an ischemic tissue may promote copper-dependent HIF-1 transcriptional activities and tissue repair.
In various aspects, the invention provides methods for treating ocular inflammation using copper chelating compounds, such as compounds other than D-penicillamine. In some embodiments, such compounds may be polyamines, such as triethylenetetramine or tetraethylenepentamine. For example, the present invention provides methods for treating inflammation secondary to ocular laser therapy.
