    体外実験

    G-1 is a nonsteroidal, high-affinity and selective agonist of GPR30 with a Ki of 11 nM[1].
    Treatment with G-1 (10 μM and 100 μM) for 48 and 72 h significantly decreases cell proliferation (P<0.001). At 72 h, the IC50 value for G-1 is calculated to be 20 μM. Treatment of A549 cells with G-1 at a concentration of 20 μM reveals a significant increase in apoptosis, consistent with its antiproliferative effect (P<0.001)[2].
    Cell cycle analysis of H295R cells after 24 h of G-1 treatment demonstrates a cell cycle arrest in the G2 phase. The presence of G-1 increases Bax expression while decreases Bcl-2[3].

    体内実験

    The results at 14 days post-injury show that the Basso mouse scale (BMS) scores are significantly higher in the G-1 group compared with the other groups (P<0.05). The number of caspase-3-positive cells in the cross sections is counted, and G-1 group has fewer positive cells compare with the other groups (P<0.05), and there is no difference between the two groups (P>0.05)[1].
    G-1 administration produces a statistically significant decrease in tumor volume from day 14 post treatment. Grafted tumors harvested after three-week treatment with G-1 show a significant decrease in tumor weight compare to vehicle treated animals[3].

    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 (6.06 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 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.
    • Protocol 2

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

      Solubility: 2.5 mg/mL (6.06 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.

    For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
    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.

    [2]

    A549 human lung cancer cells are treated with various concentrations (10 nM, 100 nM, 1 μM, 10 μM and 100 μM) of G-1 in 96-well plates and incubated for 48 or 72 h. Following incubation, MTT solution is added to each well at a concentration of 0.5 mg/mL, and incubated for 4 h at 37°C. At the end of this period, 100 µL DMSO solvent is added to each well. The absorbance values [optical density (OD)] at 570 nm of the solution in each well are read using a spectrophotometer[2].

    Four-week-old nu/nu-Forkhead box N1nu female mice are used in this study. H295R cells, 6×106, suspended in 100 μL PBS, are combined with 30 μL of Matrigel (4 mg/mL) and injected subcutaneously in the shoulder of each animal. Mice are treated 21 days after cell injection, when tumors have reached an average volume of about 200 mm3. Animals are randomly assigned to be treated with vehicle or G-1 at a concentration of 2 mg/kg/daily. Drug tolerability is assessed in tumor-bearing mice in terms of: a) lethal toxicity, i.e. any death in treated mice occurring before any death in control mice; b) body weight loss percentage=100-[(body weight on day x/body weight on day 1)×100], where x represents a day during the treatment period. Animals are sacrificed by cervical dislocation 42 days after cell injection[3].

    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.
