Catalog Number: 5297
Chemical Name: N-[2-(4'-Cyano[1,1'-biphenyl]-4-yl)propyl]-2-propanesulfonamide
Biological Activity
Selective AMPA receptor positive allosteric modulator (IC50 values are 0.15, 0.21, 1.66 and 5.65 μM for GluA2i, GluA4i, GluA3i and GluA1i respectively). Potentiates glutamate and AMPA-evoked currents in pre frontal cortex (PFC) pyramidal neurons in vitro. Has no effect on NMDA- or kainate-evoked currents; also has no effect on K+ or Na+ ion channels. Potentiates PFC glutamatergic synaptic transmission in vitro and in vivo. Induces neurite growth in combination with (S)-AMPA (Cat. No. 0254) in SH-SY5Y human neuroblastoma cells in vitro. Also reduces MPTP-induced toxicity in mice. Brain penetrant.
