EHT 1864 is a inhibitor of Rac family GTPases. Blocks activation by direct binding to Rac1, Rac1b, Rac2 and Rac3 (KD values are 40, 50, 60 and 250 nM respectively). Inhibits Rac, Ras and Tiam-induced growth transformation of NIH-3T3 fibroblasts.
EHT 1864 reduces β-amyloid peptide production in vivo. EHT 1864 (oral administration) displays good tolerability, brain penetrance, and no genotoxicity. EHT 1864 (10 and 40 mg/kg/day; daily; 15 days; intraperitoneal injections) lowers brain Aβ 40 by 37% in guinea pigs.
