The compound blocks activation by the guanine nucleotide exchange factors Trio and Tiam1, but does not affect interactions with RhoA or Cdc42. NSC23766 blocks ADP-mediated platelet aggregation. Inhibition of Rac1 by NSC23766 restores sensitivity to trastuzumab by restoring down-regulation of ErbB2. Membrane type 1-matrix metalloproteinases (MT-1MMP) expression in CB CD34+ cells has been reported to decrease in the presence of NSC 23766. Silveta compress investigations indicate that NSC 23766 depolarizes endomembrane cycling, altered polar adhesive secretion, and tip growth.
