Description

GDC-0575 dihydrochloride (ARRY-575 dihydrochloride) is an orally bioavailable CHK1 inhibitor, with an IC50 of 1.2 nM, and has antitumor activity.

IC50 & Target[1]

Chk1

1.2 nM (IC50)

In Vitro

GDC-0575 dihydrochloride is a selective and orally bioavailable CHK1 inhibitor, with an IC50 of 1.2 nM. GDC-0575 (100 nM) suppressses CHK1 activation induced by AraC by decreasing the level of Tyr15-phosphorylated CDK2. GDC-0575 (100 nM) has no effect on the viability of AML cells, but significantly reduces cell viability and induces apoptosis in combination with AraC. In addition, GDC-0575 plus AraC shows no effect on normal hematopoietic stem and progenitor cells (HSPCs)[1]. GDC-0575 shows cytotoxic activity against most of 20 melanoma cell lines tested, but several cell lines grown as tumour sphere (TS) are relatively insensitive[2].

In Vivo

GDC-0575 (7.5 mg/kg, p.o.) in combination with AraC alomost completely eradicates leukemic burden in mice transplanted with U937-Luc cells, and shows more efficient activity than AraC alone. Furthermore, GDC-0575 elevates the cytotoxicity of AraC in different primary AML models in vivo[1]. GDC-0575 (25, 50 mg/kg, p.o.) dose-dependently inhibits the growth of tumor in D20 and C002 xenografts[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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.17 mg/mL (4.81 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.17 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (21.7 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: ≥ 2.17 mg/mL (4.81 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.17 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (21.7 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.

Cell Assay
[1]

For co-culture experiments, 2 days before initiating the co-culture, feeder cells are plated onto type-I collagen-coated 96-well or 6-well plates and allowed to reach confluence. One day before starting co-culture, they are irradiated at 6.8 Gy and the culture media exchanged. On day 0 of the co-culture, AmL cells are plated at 2 × 105 cells/mL using the correspondent AmL medium. Cells are cultured at 37°C in 5% CO2-humidified incubators at indicated oxygen concentrations. For short-term culture (STC), cells are kept for 1 week in hypoxia (5% O2) with the indicated drugs: 500 nM AraC and/or 100 nM GDC-0575[1].

Animal Administration
[1]

Mice[1]
NSG mice are injected intravenously with 1 × 105-106 cells of AmL and 1-3 × 105 cells of hCB CD34+/hBM CD34+. After demonstrating AmL engraftment at 9-11 weeks through FACS analysis of tibia bone marrow aspiration, mice are treated accordingly to proper 7-day treatment regimen with daily 10 mg/kg AraC via subcutaneous injection, 7.5 mg/kg GDC-0575 suspension administered via oral gavage on every other day schedule, and/or 300 μg/kg G-CSF administered daily for 5 days via intraperitoneal injection. One week after the final dosing, mice are killed by cervical dislocation. The femurs, tibias, and pelvis are dissected and flushed with PBS. Red blood cells are lyzed via ammonium chloride. Cells are stained with human-specific FITC-conjugated anti-CD19, PE-conjugated anti-CD33, PE-Cy7-conjugated anti-CD45, and PERCP-conjugated anti-murine CD45 antibodies. Dead cells and debris are excluded via DAPI staining. A BD LSR II flow cytometer is used for analysis. Flow cytometry analysis is performed with FlowJo software. More than 100,000 DAPI-negative events are collected. Engraftment of AmL is said to be present if a single population of mCD45-hCD45+CD33+CD19- cells is present without accompanying mCD45-hCD45+CD33−CD19+cells[1].

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.
