Primary TargetDock5

Cell permeable: yes

General description

A cell-permeable, bioavailable, non-toxic benzenesulfonamide compound that directly blocks Dock5-mediated Rac activation (k_cat/K_M = 7.9 x 10⁴ & 9.5 x 10⁴ M^-1s^-1 for Rac1 & Rac2 by Dock5-DHR2, respectively) with selectivity over RhoA and Cdc42. At higher concentrations, affects Dock1 and Dock2 guanine nucleotide exchange factor activity. Shown to reversibly perturb podosome organization and inhibit osteoclastic bone degradation in a dose-dependent manner. Efficiently prevents both arthritis and metastasis-induced bone loss while preserving bone formation in several osteolytic disease mouse model (25 mg/kg, i.p. or i.v., 5 days a week for 4 weeks). Unlike alendronate (Cat. No. 126855), C21 does not impair bone formation.
