A cell-permeable, non-cytotoxic, aqueous soluble (181uM in PBS, pH 7.4) pyrimidinylthiourea that targets Cdc42 GEF ITSN/intersectin and adjacent GTP/GDP binding site and effectively inhibits EGF-stimulated Cdc42 activity (1h pretreatment; 50uM) and Cdc42-dependent microspike/filopodia formation in serum-starved Swiss 3T3 fibroblast cultures without affecting RhoA- or Rac1-dependent functions. Short-term ZCL278 exposure in primary murine neonatal cortical neurons is shown to dramatically abolish neurite branching (50uM).
