Ubenimex (INN), also known more commonly as bestatin, is a competitive, reversible protease inhibitor. It is an inhibitor of arginyl aminopeptidase (aminopeptidase B), [3] leukotriene A4 hydrolase (a zinc metalloprotease that displays both epoxide hydrolase and aminopeptidase activities), [4] alanyl aminopeptidase (aminopeptidase M/N), [5] leucyl/cystinyl aminopeptidase (oxytocinase/vasopressinase), [6] [7] and membrane dipeptidase (leukotriene D4 hydrolase). It is being studied for use in the treatment of acute myelocytic leukemia [8] and lymphedema. [9] It is derived from Streptomyces olivoreticuli . [10] Ubenimex has been found to inhibit the enzymatic degradation of oxytocin, vasopressin, enkephalins, and various other peptides and compounds.[ citation needed ]
