  3. PQ401

PQ401 is a potent inhibitor of IGF-IR signaling. PQ401 inhibits IGF-I-stimulated IGF-IR autophosphorylation with an IC50 of 12.0 μM in a series of studies in MCF-7 cells. PQ401 is effective at inhibiting IGF-I-stimulated growth of MCF-7 cells (IC50, 6 μM). PQ401 is a potential agent for breast and other IGF-I-sensitive cancers. PQ401 induces caspase-mediated apoptosis.

    Description

    PQ401 is a potent inhibitor of IGF-IR signaling. PQ401 inhibits IGF-I-stimulated IGF-IR autophosphorylation with an IC50 of 12.0 μM in a series of studies in MCF-7 cells. PQ401 is effective at inhibiting IGF-I-stimulated growth of MCF-7 cells (IC50, 6 μM). PQ401 is a potential agent for breast and other IGF-I-sensitive cancers. PQ401 induces caspase-mediated apoptosis[1].

    IC50 & Target

    IGF-IR; apoptosis[1]

    In Vitro

    PQ401 (1, 5, 10, 25, and 50 μM; 3 days) inhibits proliferation of cultured MCF-7 cells grown in serum or IGF-I in MCF-7 cells[1].
    Twenty-four hours of treatment with 15 μM PQ401 induces caspase-mediated apoptosis[1].
    PQ401 inhibits autophosphorylation of the IGF-IR kinase domain at concentrations <100 nM, with an IC50 <1 μM.

    Cell Proliferation Assay[1]

    Cell Line: Breast cancer cells, MCF-7 cells
    Concentration: 1, 5, 10, 25, and 50 μM
    Incubation Time: 3 days
    Result: Significantly reduced proliferation (IC50, 8 μM) at concentrations in the range of 1 μM.
    Produced a dramatic reduction in cell number from pretreatment levels at concentrations >10 μM.
    In Vivo

    PQ401 (50 or 100 mg/kg; i.p.; thrice a week) results in a significant dose-dependent reduction in tumor growth over the course of the study. PQ401 reduces the growth rate of MCNeuA cells implanted into mice[1].

    MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Model: Female mice were MCNeuA tumor cells[1]
    Dosage: 50 or 100 mg/kg
    Administration: Administered i.p. thrice a week; 24 days
    Result: Resulted in a significant dose-dependent reduction in tumor growth. Tumor growth in the animals treated with 100 mg/kg was 20% of that in the vehicle-treated controls. This dosing protocol was well tolerated by the animals.

    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: ≥ 1.43 mg/mL (4.18 mM); Clear solution

      This protocol yields a clear solution of ≥ 1.43 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (14.3 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: 1.43 mg/mL (4.18 mM); Suspended solution; Need ultrasonic

      This protocol yields a suspended solution of 1.43 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 (14.3 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    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.

    • 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.
