MedKoo CAT#: 510327

CAS#: 1177865-17-6 (HCl)

Description: NSC23766 is a potent Rac1 inhibitor. NSC23766 disrupted polar secretion of adhesive, polarization of endomembranes, and tip-focused growth in the rhizoid. NSC23766 can acts as a competitive antagonist at muscarinic acetylcholine receptors. NSC23766 exerts anti-influenza virus properties by affecting the viral polymerase complex activity. NSC23766 suppresses CREB signaling by targeting NMDA receptor function.
