Ubenimex is a dipeptide, which specifically inhibits the activity of leukotriene A4 hydrolase, aminopeptidase B and leucine aminopeptidase of the cell membrane. The drug was isolated from Streptomyces oliooreticuli in 1976 in Nippon Kayaku, Japan and approved for the treatment of acute non-lymphocytic leukemia under the name Bestatin. In the USA the drug is currentlu in Phase II for the treatment of pulmonary arterial hypertension and lymphedema.

Sample Use Guides

In Vivo Use Guide

Administer 30 mg ubenimex orally once a day.

Route of Administration: Oral

In Vitro Use Guide

MT-1, MOLT-4, HL-60, K562 and Raji cells were cultured in the presence of ubenimex (4.5, 45, 450 ug/ml and 4.5 mg/ml) at 37C. The number of viable HL-60 cells decreased with time at a high concentration of the drug (4.5 mg/ml) with time. The number of viable MT-1 cells was also decreased at the concentrations 4.5 mg/ml and 450 ug/ml. The number of viable MOLT-4 cells did not decrease even at high concentrations. The number of viable Raji cells also decreased at 4.5 mg/ml, but was not affected at 450 ug/ml.
