TNP-470 is a methionine aminopeptidase-2 inhibitor and also an angiogenesis inhibitor.
No significant difference of apoptotic cell numbers is observed between cells treated with TNP-470 and the controls. The IC50s of TNP-470 are 16.86±0.9 μg/mL, 3.16±0.6 μg/mL and 1.78±0.8 μg/mL for KKU-M213 cells at 24, 48 and 72 h, respectively. The results show that TNP-470 significantly reduces the number of migrated cells and invaded cells as compared with the vehicle treated group. TNP-470 decreases the migrated cells of KKU-M213 to 26% and of KKU-M214 to 11% (PMMP2, MMP9 and c-MYC in TNP-470 treated cells are significantly suppressed compared to the vehicle treated cells[1].
TNP-470 attenuates (PmRNA, compare to chow-fed and high-fat fed controls. TNP-470 decreases energy intake and increases energy expenditure[2].
Individually housed, 4 wk old male C57BL/6 mice are used in this study. After a 1 wk acclimation period, mice are randomly allocated to receive either standard chow diet or high-fat diet for 6.5 wk. Throughout the high-fat feeding period the mice are treated with TNP-470 at a dose of 20 mg/kg body weight, injected subcutaneously every other day (TNP
n=7) or a vehicle injection of an equivalent volume (HFF controls
n=7). Vehicle injections contain 3% ethanol in phosphate-buffered saline. Chow-fed control mice (chow
n=8) are sham injected. Mice are fed ad libitum with food replaced every 2 or 3 days. Body weights are collected three times per week. After 6.5 wk of feeding, animals are fasted for 16-h and sacrificed. Final body, liver, and epididymal adipose tissue weights are measured. Liver and adipose tissue samples are frozen in liquid nitrogen and stored at -80°C for subsequent analysis[2].
MTT assays are applied to test cell viability. In brief, 3×103 cells per well are seeded in a 96-well plate and incubated with various concentration of TNP-470 for 24, 48, and 72 h at 37°C, 5% CO2. For comparison, cells cultured in the absence of TNP-470 are used as a control. After an incubation period, 10 μL MTT (0.5 mg/mL final concentration) is added to each well. After 4 h of additional incubation, 100 μL of 0.01 N HCl in isopropanol is added to dissolve the crystals. Absorption at 570 nm is determined by ELISA plate reader[1].
