Biological Activity

Ubenimex (Bestatin) is an inhibitor of aminopeptidase B, leukotriene A4 hydrolase, aminopeptidase N (Ki = 0.001 - 90 mM). Ubenimex inhibits enkephalin metabolism and leukotriene A4 hydrolase. Bestatin also inhibits tumor cell proliferation. Bestatin induced cell growth inhibition and phenotypic changes of HL-60 and HL-60R cell lines. In vitro, the upregulation of CD13/aminopeptidase N was found after 1 hr, however, the downregulation was observed after 3 hrs incubation with Ubenimex (Bestatin). On the other hand, the downregulation of CD15 and CD33 was observed after both one and 3 hrs incubation. Ubenimex may also be an effective anti-leukemic agent in vivo.

Results Compared with those in PM group, the rabbits in group BPM showed significantly reduced LTB4 production in the lungs (P < 0.05), up-regulated cAMP/ PKA and Rap1 signaling pathway activities (P < 0.05), and alleviated lung hyper-permeability and inflammation (P < 0.05).

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
