Bestatin trifluoroacetate (Ubenimex) is a novel and potent inhibitor of CD13 (Aminopeptidase N)/APN and leukotriene A4 hydrolase with anticancer activity. Bestatin has been known as an immunomodulating agent in anti-leukemia treatment.

In ATRA-sensitive APL NB4 cells, bestatin promotes ATRA-induced differentiation and prevents ATRA-driven activation of p38 MAPK. ATRA-resistant APL MR2 cells have a differentiation block that is not reversible by bestatin. When CD13 is ligated with the anti-CD13 antibody WM-15, p38 MAPK is phosphorylated, Bestatin's suppression of p38 MAPK phosphorylation is lessened, and the enhancement of Bestatin on ATRA-inducing differentiation in NB4 cells is entirely eliminated[2]. Cells treated with bestatin (600 μM) undergo delayed cell cycle progression because their frequency and growth rate of division are reduced. Bestatin is not harmful to D. discoideum cells at concentrations between 0-600 μM, but it does suppress the frequency of mitosis and the intrinsic multinuclearity in these cells. In lysates of PsaA-GFP- and GFP-expressing cells, bestatin decreases aminopeptidase activity by 69.39% ± 10.5% and 39.93% ± 18.7% of control, respectively[4].

When compared to diabetic vehicle-treated mice, bestatin (20 μM) dramatically inhibits MMP-9 specific gelationolytic band densities and considerably lowers CD13 expression in diabetic mice. In diabetic mice, treatment with betatin dramatically reduces the expression of heparanase and VEGF. In the retinas of diabetic mice, intravitreal bestatin therapy dramatically reduces the expression of VEGF and HIF-1α. Furthermore, intravitreal bestatin therapy effectively inhibits the increased expression of heparanase in the retinas of diabetic mice[1]. Before the antigen-potentiated humoral response to SRBC, bestatin (10, 1, and 0.1 mg/kg, ip) administration increases the number of splenocytes that produce hemolytic anti-SRBC antibodies (PFC) and the 2-ME-resistant serum hemagglutinin titer (at a dose of 0.1 mg/kg). When mice are given bestatin (1 and 0.1 mg/kg) five times on different days following cyclophosphamide injection, the drug's suppressive effect on the number of PFC remains unchanged. In fact, on day seven following antigen stimulation, bestatin (1 mg/kg) causes a further decrease in total anti-SRBC hemagglutinins.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
