187-1, N-WASP inhibitor TFA 

187-1, N-WASP inhibitor TFA, a 14-aa cyclic peptide, is an allosteric neural Wiskott-Aldrich syndrome protein (N-WASP) inhibitor. 187-1, N-WASP inhibitor TFA potently inhibits actin assembly induced by phosphatidylinositol 4,5-bisphosphate (PIP2) with an IC₅₀ of 2 μM. 187-1, N-WASP inhibitor TFA prevents the activation of Arp2/3 complex by N-WASP by stabilizing the autoinhibited state of the protein^[1][2].
