  • (e) FRAX597 (1 μM) for 1 h, and seeded onto Matrigel. 2F-2B cells were supplemented with exosomes (30 μg). After 24 h culture, tube formation was analysed and imaged. Scale bar = 50 μm. (representative images from n=3, *p<0.05, **p<0.01 and NS = no significant difference).

    Oncotarget, 2016, 7(15):19709-22. FRAX597 purchased from Selleck.

    (A) Cells were cultured on glass coverslips and pretreated with IPA3 (5 μM) or FRAX597 (50 nM) for 30 min and subsequently exposed to 1 mM sevoflurane or isoflurane for 30 min. The redistribution of filamentous actin and globular actin was determined by phalloidin–Alexa568 and DNAse I-Alexa488 staining and immunofluorescence microscopy. Magnification, 400 × (the scale bar represents 50 μm). Similar results were obtained in three independent experiments.

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

Kinase Assay:[1]
+ Expand

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 Research:[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.

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
