Solubility (25°C)* In vitro DMSO 5 mg/mL (8.95 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO Corn oil
0.25mg/ml Taking the 1 mL working solution as an example, add 50 μL of 5 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description FRAX597 is a potent, ATP-competitive inhibitor of group I PAKs with IC50 of 8 nM, 13 nM, and 19 nM for PAK1, PAK2, and PAK3, respectively.
Targets
PAK1 [1]
(Cell-free assay)		 PAK2 [1]
(Cell-free assay)		 PAK3 [1]
(Cell-free assay)
8 nM 13 nM 19 nM
In vitro FRAX597 (100 n M) displays a significant inhibitory capacity toward YES1 (87%), RET (82%), CSF1R (91%), TEK (87%), PAK1 (82%), and PAK2 (93%), while displays minimal inhibitory activity towards the group II PAKs: PAK4 (0%), PAK6 (23%), and PAK7 (8%). FRAX597 treatment dramatically impairs the proliferation of Nf2-null SC4 Schwann cells (SC4 cells). FRAX597 displays an IC50 value of 48 nM against wild type PAK1, while IC 50 values against the V342F and V342Y PAK1 mutants are higher than 3μM and 2 μM, respectively.[1] FRAX597 inhibits the proliferation and motility of both benign (Ben-Men1, 3μM) and malignant (KT21-MG1, 0.4 μM) meningiomas cells after treating of 72 h.[2]
In vivo In NOD/SCID mice which bearing Nf2-/-SC4 Schwann cells, FRAX597 (100 mg/kg/day, p.o.) causes more significant tumor growth inhibition cpmpared with control mice.[1] In SCID mice with orthotopic meningioma, FRAX597 (90 mg/kg/day, p.o.) significantly suppresses tumor growth.[2] In KrasG12D mice, treatment with FRAX597 (90 mg/kg/day, p.o.) causes tumor regression and loss of Erk and Akt activity.[3]

Protocol (from reference)

Kinase Assay:[1]
  • Determination of Enzyme IC50 Values

    IC50 values are determined using a 10 concentration point, non-radioactive, functional assay that employs a fluorescence-based, coupled-enzyme format, according to the manufacturer’s protocol (Z’-LYTE@biochemical assay). Kinase selectivity is determined using both the Z’-LYTE@ and Adapta@ kinase assay format.
Cell Assay:[1]
  • Cell lines

    SC4 cells

  • Concentrations

    1 μM

  • Incubation Time

    4 day

  • Method

    30,000 cells/well are plated in 12-well dishes in triplicate. Cell growth media with or without FRAX597 is replaced daily. At indicated time points, cells from individual wells are trypsinized and counted using a Coulter counter.
Animal Study:[2]
  • Animal Models

    SCID mice with orthotopic meningioma model

  • Dosages

    90 mg/kg/day

  • Administration

    p.o.
