General description

A cell-permeable pyrimidine compound that specifically and reversibly inhibits Rac1 GDP/GTP exchange activity by interfering with the interaction between Rac1 and Rac-specific GEFs (guanine nucleotide exchange factors) Trio and Tiam1 (IC50 ~50 µM). Shown to effectively inhibit Rac1-mediated cellular functions in NIH3T3 and PC-3 cells (effective dose ~50 to 100 μM). Exhibits no effect on Cdc42 or RhoA activation and does not affect Rac1 interaction with BcrGAP or PAK1. Reduces TRAP-induced and collagen stimulated platelet aggregation (IC50 = 50 mM and 64 mM, respectively).

Biochem/physiol Actions

Cell permeable: yes
Primary Target
Rac1
Product does not compete with ATP.
Reversible: yes
Target IC50: ~50 µM against Rac1 GDP/GTP exchange activity; 50 mM and 64 mM against TRAP-induced and collagen stimulated platelet aggregation

Packaging

Packaged under inert gas

Warning

Toxicity: Carcinogenic / Teratogenic (D)

Reconstitution

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 3 months at -20°C.
