Tezampanel, also known as LY 293558 and NGX-424, is a drug originally developed by Eli Lilly, which is a competitive antagonist of the AMPA and kainate subtypes of the ionotropic glutamate receptor family. Tezampanel was in phase II clinical trial for treatment migraine, but this study was discontinued. Also this drug has several others potential pharmacological actions, one of them is anxiety disorders

LY293558 (Tezampanel) had a rank order of potency of GLU(K5) > or = GLU(K5/6) approximately GLU(A2i) approximately GLU(K2/5) approximately GLU(A1i) approximately GLU(A2o) approximately GLU(A3i) approximately GLU(A1o) > or = GLU(A3o) > or = GLU(A4i) approximately GLU(A4o) and >100 microM affinity for rat cortical GABA(A) receptors. Comparison of the blockade of AMPA- vs N-methyl-D-aspartate (NMDA)-induced inward currents demonstrated that LY293558 was five-fold more potent as an antagonist at AMPA vs NMDA receptors in vitro.
