Ubenimex

Chemical compound

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]
