Description

EHT 1864 is a potent Rac family GTPase inhibitor with Kd of 40 nM, 50 nM, 60 nM and 250 nM for Rac1, Rac1b, Rac2 and Rac3, respectively. EHT 1864 attenuates glucose-stimulated insulin secretion in pancreatic β-cells. EHT 1864 specifically inhibits glucose-induced Rac1 activation and membrane association and associated downstream signaling events culminating in inhibition of GSIS.

How to use

In Vitro:

EHT 1864 selectively inhibits Rac-induced lamellipodia formation, and specifically reverses cell transformation induced by constitutively activated mutants of Rac1 and Tiam1. EHT 1864 strongly impaires oncogenic Ras-induced cell proliferation in NIH 3T3 cells stably expressing H-Ras(61L) protein. EHT 1864 also reduces both extracellular and intracellular levels of Aβ peptides by inhibiting the γ-secretase-dependent cleavage of APP. In cultured hippocampal pyramidal neurons, EHT 1864, via inhibition of Rac1, rescues the phenotype induced by Rich2 knock-down.

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.
