Chemical Name: N6-[2-[[4-(Diethylamino)-1-methylbutyl]amino]-6-methyl-4-pyrimidinyl]-2-methyl-4,6-quinolinediamine trihydrochloride

Biological Activity

Selective inhibitor of Rac1-GEF interaction. Prevents Rac1 activation by Rac-specific guanine nucleotide exchange factors (GEFs) TrioN and Tiam1 (IC50 ~ 50 μM) without affecting Cdc42 or RhoA activation. Inhibits Rac1-mediated cell functions and is reported to reverse tumor cell phenotyes in prostate cancer cells.

Technical Data

Soluble to 100 mM in water and to 100 mM in DMSO
>99 %
Desiccate at RT
