Description

FRAX597 is a potent group I p21-activated Kinases (PAKs) inhibitor with IC50 of 8, 13 and 19 nM for PAK1, 2 and 3.

IC50 & Target[1]

PAK1

8 nM (IC50)

PAK2

13 nM (IC50)

PAK3

19 nM (IC50)

In Vitro

FRAX597 is determined to be a potent, ATP-competitive inhibitor of group I PAKs (PAK 1-3), with biochemical IC50 values as follows: PAK1 IC50=8 nM, PAK2 IC50=13 nM, PAK3 IC50=19 nM. The IC50 toward PAK4, a member of group II PAKs is >10 μM. At a concentration of 100 nM FRAX597 displays a significant (>80% inhibition) inhibitory capacity toward YES1 (87%), RET (82%), CSF1R (91%), TEK (87%), PAK1 (82%), and PAK2 (93%). When measured using the Kinase Glo Assay in the presence of 20 nM protein and 1 μM ATP, FRAX597 displayed an IC50 value of 48 nM against wild type PAK1, while IC50 values against the V342F and V342Y PAK1 mutants are higher than 3 μM and 2 μM, respectively[1].

In Vivo

Analysis of the flux reading for the animals in the two cohorts demonstrates a significantly slower tumor growth rate in FRAX597-treated mice compared with control mice. After 14 days of treatment the animals are sacrificed and the tumors excised and weighed. FRAX597-treated cohort shows significantly lower average tumor weight compared with the control cohort [1].

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 (2.56 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 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 (2.56 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.

    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
[1]

30,000 SC4 cells/well are plated in 12-well dishes in triplicate. Cell growth media with or without FRAX597 (1 μM) is replaced daily. At indicated time points, cells from individual wells are trypsinized and counted using a Coulter counter. Statistical analysis is performed using a Student's t test. For cell cycle analysis, cells are harvested, washed once with PBS and fixed in cold 70% ethanol. Fixed cells are resuspended in propidium iodide (PI) buffer (50 μg/mL PI, 250 mg/mL RNase A in PBS) and incubated overnight at 4°C in the dark. Cell cycle distribution is evaluated using Coulter Epics XL flow cytometer. Data are analyzed using WinMDI software[1].

Animal Administration
[1]

Mice[1]
Nf2-/- SC4 Schwann cells are transduced by lentiviruses carrying pLuc-mCherry and sorted by FACS. 5×104 cells are transplanted into the sciatic nerve sheath of NOD/SCID mice (8 weeks of age) by intraneural injection. Tumor progression is monitored weekly by bioluminescence imaging (BLI) on an IVIS-200 system. The representative images from bioluminescence imaging (BLI) of mice carrying orthotopic tumors treated with FRAX597 (100 mg/kg) or vehicle control at day 14 of treatment. NOD/SCID mice are injected intraneurally with 5×104 SC4/pLuc-mCherry cells and are enrolled into treatment after 10 days. Mice are treated daily for 14 days and imaged every 3 days to follow tumor development.

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.
