Abstract (en)

[origin: WO9728803A1] Analogs of erythro-hydroxynonyladenine (EHNA) are disclosed which have been modified by bonding various types of moieties to the #8 or #9 carbon atoms in the "side chain" portion of the molecule. The compounds inhibit the intracellular enzymatic activity of adenosine deaminase and are therapeutically effective in reducing hypoxic and ischemic damage in heart and brain tissue.
