NSC 23766 (hydrochloride) Structural

What is NSC 23766 (hydrochloride)?

Description

Rac1 is a GTPase that is involved in the regulation of the cell cycle, cell-cell adhesion, motility, and differentiation. Rac1 is activated by its interaction with specific guanine nucleotide exchange factors (GEFs). NSC 23766 is a cell-permeable, reversible inhibitor of Rac1 activation by the Rac-specific GEFs TrioN and Tiam 1 (IC50 = 50 μM). It has no effect on the closely related GTPases, Cdc42 and RhoA. NSC23766 has been used to investigate the role of Rac1 in such diverse cellular functions as stem cell mobilization, epithelial cell migration, angiogenesis, leukemia cell migration and growth, and gene expression.

The Uses of NSC 23766 (hydrochloride)

NSC 23766 is a highly soluble and membrane permeable Rac GTPase inhibitor. NSC 23766 inhibits Rac GTPase by targeting Rac activation by guanine nucleotide exchange factor (GEF). NSC 23766 has been shown to inhibit the anchorage-independent growth and invasion phenotypes of human prostate cancer PC-3 cells.

The Uses of NSC 23766 (hydrochloride)

NSC23766 trihydrochloride has been used as a ras-related C3 botulinum toxin substrate 1 (RAC1) inhibitor.

Definition

ChEBI: NSC 23766 trihydrochloride is a hydrochloride resulting from the formal reaction of NSC 23766 with 3 mol eq. of hydrogen chloride. An inhibitor of the signalling G-protein known as RAC1 (Ras-related C3 botulinum toxin substrate 1). It has a role as an EC 3.6.5.2 (small monomeric GTPase) inhibitor, an antiviral agent, an apoptosis inducer and a muscarinic antagonist. It contains a NSC 23766.

Biochem/physiol Actions

NSC23766 is an inhibitor of Rac1, a Rho-family GTPase. 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.
