PICK1 PDZ Domain Inhibitor, FSC231-Calbiochem

C₁₃H₁₀Cl₂N₂O₃

313.14

A cell-permeable acryloylcarbamate compound that selectively targets the PDZ (PSD-95/Discs-large/ZO-1 homology) domain of PICK1 (protein interacting with C kinase 1), but not PDZ domains of PSD-95 (postsynaptic density protein 95) and GRIP1 (glutamate receptor interacting protein 1), effectively competing against dopamine transporter/DAT (K_i ~10 µM in competitive binding assays), GluR2 (K_i ~10 µM in competitive binding assays), and mRluR7a (~70% inhibition by Co-IP using lysates from 50 µM FSC231-treated HEK293), c-terminus binding to PICK1 PDZ. Shown to accelerate GluR2 surface recycling after NMDR-induced internalization (t_1/2 = 7.5 vs 10 min with and without 50 µM FSC231 treatment) in rat hippocampal neurons and prevent both LTD (% long-term depression = 74 vs 50 with and without 50 µM FSC231 treatment) and LTP (% long-term potentiation = 137 vs 266 with and without 50 µM FSC231 treatment) in murine hippocampal slices.

Shown to accelerate internalized GluR2 surface recycling and suppress both long-term depression and potentiation in rat and murine hippocampal neurons.
