Ubenimex Usage And Synthesis

Chemical Properties	white powder
Usage	Ubenimex is a competitive aminopeptidase B inhibitor with an IC50 of 100 mg/ml for K562 cells. Proliferation of all the cell lines except KG1 was inhibited by bestatin. P39/TSU, HL60 and U937 were highly sensitive, with 50% growth inhibitory concentration
Usage	Bestatin is "pseudo"-dipeptide isolated from Strepotmyces olivreticuli in 1976. Bestatin is a potent aminopeptidase B inhibitor with no carboxypeptidase activity. Bestatin acts as an immunomodulator by activating macrophages and T lymphocytes. Bestatin also exhibits good antitumour activity and is has been investigated in clinical trials.
