Chemical Name: 3,6-Dibromo-α-[(dimethylamino)methyl]-9H-cabazole-9-ethanol

Biological Activity

Inhibitor of neural Wiskott-Aldrich syndrome protein (N-WASP) activity. Interacts with the regulatory GTPase-binding domain of N-WASP; inhibits activation of Arp2/3 complex by maintaining N-WASP in an inactive conformation. Also inhibits PIP2-induced actin polymerization (EC50 ~ 4μM).

Technical Data

Soluble to 100 mM in DMSO
>99 %
Store at +4°C
