Description

TNP-470 is a methionine aminopeptidase-2 inhibitor and also an angiogenesis inhibitor.

IC50 & Target

methionine aminopeptidase-2[1], angiogenesis[2]

In Vitro

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% (P<0.01). Similarly, TNP-470 also significantly affects cell invasion, the number of invaded cells is reduced to 25% in KKU-M213 (P<0.01) and to 15% in KKU-M214 (P<0.01). The relative expressions of MMP2, MMP9 and c-MYC in TNP-470 treated cells are significantly suppressed compared to the vehicle treated cells[1].

In Vivo

TNP-470 attenuates (P<0.05) liver lipid accumulation compared to high fat fed (HFF) mice. By day 5, TNP-470 treated mice consume significantly less grams of high fat food than vehicle treated HFF mice. By day 15 of treatment, TNP-470 mice are consuming an equivalent number of calories to that of chow fed mice, despite the provision of high fat diet. Treatment with TNP-470 increases (P<0.05) expression of adipose tissue LPL mRNA, compare to chow-fed and high-fat fed controls. TNP-470 decreases energy intake and increases energy expenditure[2].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (6.22 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (6.22 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Cell Assay
[1]

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].

Animal Administration
[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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
