Description

Description générale

A cell-permeable furylidenebenzohydrazide compound that acts as a reversible inhibitor against Eya2 C-terminal Eya domain (ED) protein tyrosine phosphatase (PTP) activity (IC₅₀ = 4.1 µM; 100 nM ED & 5 µM Mg²⁺; Substrate = 25 µM OMFP) via affinity docking at an allosteric pocket located opposite to the active site (K_D = 6.1 or 2.0 µM, respectively, with or without 5 mM exogenous Mg²⁺; K_D = 0.8 µM with 10 mM EDTA and no exogenous Mg²⁺), while being ineffective against the PTP activity of Eya3 & PTP1B or the Ser/Thr phosphatase activity of PPM1A & Scp1. Shown to reduce Eya2 overexpression-induced migration enhancement in MCF10A cultures (17% vs. 54% enhancement with or without 10 µM inhibitor). The inhibition appears to be non-competitive with respect to substrate in the presence of 5 mM Mg²⁺, while mixed mode of inhibition is observed at a low Mg²⁺ concentration of 5 µM.
