Biological Activity

Description FRAX597 is a potent and ATP-competitive inhibitor of group I p21-activated kinases (PAKs) with IC50 values of 8 nM, 13 nM and 19 nM for PAK1, PAK2 and PAK3, respectively.
Targets PAK1 PAK2 PAK3      
IC50 8 nM 13 nM 19 nM      

Protocol

Cell experiment [1]:

Cell lines

Nf2-null SC4 Schwann cells

Preparation method

Limited solubility. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reaction Conditions

96 h

Applications

FRAX597 treatment significantly inhibits cellular proliferation. FRAX597-treated cells are increased in G1phase (74% versus 50% in control-treated cells) and decreased in the fraction of cells in S phase (12% versus 27% in control) and G2/M phase (11% versus 22% in control).

Animal experiment [1]:

Animal models

NOD/SCID mice (8 weeks of age), transplanted with Nf2-/- SC4 Schwann cells into the sciatic nerve sheath.

Dosage form

100 mg/kg; oral; once daily for 14 days.

Applications

FRAX597-treatment significantly slows tumor growth rate in mice compared to control mice. Moreover, FRAX597-treated cohort exhibits prominently lower average tumor weight compared to the control cohort.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

FRAX597 is a small-molecule inhibitor of the group 1 p21-activated kinases (PAKs) with IC50 values of 8nM, 13nM and 19nM, respectively for PAK1, PAK2 and PAK3 [1].

The PAKs family includes two sub groups: 1 and 2. These kinases take participate in the growth of various types of cancers. FRAX597 is developed to be an inhibitor of group 1 PAKs from the initial hits of a high throughput screen. It is an ATP-competitive inhibitor of PAK 1-3. To group 2 PAKs, FRAX597 shows minimal inhibitory activity. The inhibition mechanism of FRAX597 is that it binds PAK by targeting the ATP binding site and competes with ATP. FRAX597 is reported to suppress cell proliferation by arresting cell cycle in G1 without impacting cell viability in Schwann cells. In vivo assay also demonstrates FRAX597 can suppress tumor growth in an orthotopic model of NF2. This effect on the cells has been proved to be mediated through the inhibition of the group I PAKs [1].
