While free radicals and inflammation constitute major routes of neuronal injury occurring in amyotrophic lateral sclerosis (ALS), neither antioxidants nor non-steroidal anti-inflammatory drugs have shown significant efficacy in human clinical trials. We examined the possibility that concurrent blockade of free radicals and prostaglandin E2 (PGE2)-mediated inflammation might constitute a safe and effective therapeutic approach to ALS. We have developed 2-hydroxy-5-[2-(4-trifluoromethylphenyl)-ethylaminobenzoic acid] (AAD-2004) as a derivative of aspirin. AAD-2004 completely removed free radicals at 50 nM as a potent spin-trapping molecule and inhibited microsomal PGE2 synthase-1 (mPGES-1) activity in response to both lipopolysaccharide-treated BV2 cell with IC50 of 230 nM and recombinant human mPGES-1 protein with IC50 of 249 nM in vitro. In superoxide dismutase 1G93A transgenic mouse model of ALS, AAD-2004 blocked free radical production, PGE2 formation, and microglial activation in the spinal cords. As a consequence, AAD-2004 reduced autophagosome formation, axonopathy, and motor neuron degeneration, improving motor function and increasing life span. In these assays, AAD-2004 was superior to riluzole or ibuprofen. Gastric bleeding was not induced by AAD-2004 even at a dose 400-fold higher than that required to obtain maximal therapeutic efficacy in superoxide dismutase 1G93A. Targeting both mPGES-1-mediated PGE2 and free radicals may be a promising approach to reduce neurodegeneration in ALS and possibly other neurodegenerative diseases.
