General description

Wiskostatin is a dibrominated carbazole. The N-alkylated side chain has a chiral hydroxyl group and a terminal tertiary amine.

Application

Wiskostatin has been used:
  • as a small-molecule inhibitor of Wiskott-Aldrich syndrome protein (WASP) in human osteosarcoma U2OS cells and mouse-tail fibroblast cell lines
  • as a neural (N)-WASP inhibitor in cultured neurons and in the human embryonic kidney (HEK293) cells expressing HA-Parkin
  • as a neural (N)-WASP inhibitor in dorsal root ganglion (DRG) cells to investigate vascular endothelial growth factor (VEGF) effect on the actin related protein 2/3 complex (Arp 2/3)

Biochem/physiol Actions

Wiskostatin is a selective inhibitor of N-WASP, a ubiquitously expressed member of the Wiskott-Aldrich Syndrome protein (WASp) family that regulates actin polymerization. Wiskostatin inhibits actin-dependent cellular functions, including migration, transmembrane transport and phagocytosis.
Wiskostatin mediates the inhibition of cytokinesis. It interacts with WASP especially at the regulatory guanosine-5′-triphosphate (GTP)ase-binding domain (GBD).
