    Description

    Teprenone is an anti-ulcer agent, and works as an inducer of heat shock proteins (HSPs).

    IC50 & Target[1]

    HSP

     

    In Vitro

    Teprenone is an inducer of HSPs. Teprenone (Geranylgeranylacetone, 1 μM) significantly prevents ethanol-induced exfoliation, and reduces lactate dehydrogenase (LDH) release in gastric mucosal cells. Teprenone (1 μM) gradually increases HSC70 level, and rapidly accumulates the stress-inducible HSP90, HSP70, and HSP60 concentrations within 30-60 min. Teprenone also activates the heat shock factor 1[1].
    Teprenone (0-20 μM) slightly increases human umbilical vein endothelial cell (HUVEC) viability following irradiation (IR). Teprenone (10 μM) exhibits no effects on HUVEC migration and invasion, but enhances HUVEC tube formation and wound healing both with and without IR. Teprenone (10 μM) also promotes angiogenesis by inducing VEGF and eNOS expression in HUVECs[3].

    In Vivo

    Teprenone (200 mg/kg, p.o.) results in the accumulation of HSP70 mRNA in rats, and the accumulation is enhanced by stress addition in the mucosa of Teprenone-pretreated rats compared with that of vehicle-pretreated rats. Teprenone (200 mg/kg, p.o.) markedly suppresses the ulcer formation after 2- and 4-hour stress loading in rats[1].
    Teprenone (200 mg/kg daily) induces HSP72 in retinal ganglion cells (RGCs) from rat retinas. Teprenone significantly reduces the loss of RGCs (evaluated after intraocular pressure (IOP) elevation), lessens optic nerve damage, decreases the number of TUNEL-positive cells in the RGC layer, and increases HSP72 in a rat model of glaucoma[2].
    Teprenone (200 mg/kg, p.o.) shows protective effect on radiation-induced intestinal injury in mice[3].

    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    40% PEG300    5% Tween-80    45% Saline

      Solubility: 2.5 mg/mL (7.56 mM); Suspended solution; Need ultrasonic

      This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

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

      Solubility: 2.5 mg/mL (7.56 mM); Suspended solution; Need ultrasonic

      This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

      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.

    Cell Assay
    [3]

    Human umbilical vein endothelial cells (HUVECs) are seeded onto 48-well plates at a density of 1 × 102 cells/well before Teprenone and/or radiation treatment. Cell viability is determined at 48 h after treatment using 0.5 mg/mL MTT solution in serum-free media. This solution is incubated with the cells for 2 h in the 37°C humidified atmosphere containing 5% CO2. Then, the MTT solution is removed, and the cells are dissolved in 100 µL of DMSO. Optical densities of the supernatants are measured at 540 nm with an ELISA spectrophotometer[3].

    Animal Administration
    [1]

    Male Wister strain rats weighing approximately 250 g are individually housed in wire-mesh cages in a room maintained at 23°C on a 12-hour light-dark cycle. Rats are allowed free access to a standard laboratory chow. Teprenone (200 mg/kg; as emulsion with 5% gum arabic and 0.008% α-tocopherol) or vehicle (5% gum arabic emulsion containing 0.008% α-tocopherol) is given orally in a volume of 5 mL/kg through a metal tubing attached to a 6-mL syringe. Two hours later, rats are placed in restraint cages and then vertically immersed in water at 23°C to the level of the xyphoid process. The rats are killed by decapitation at the indicated times[1].

    • 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.
