4,6-Dichloro-3-[(1E)-3-oxo-3-(phenylamino)-1-propenyl]-1H-indole-2-carboxylic acid sodium salt

Treatment of stroke (N-methylD-aspartate NMDA receptor antagonist).

ChEBI: 3-(3-anilino-3-oxoprop-1-enyl)-4,6-dichloro-1H-indole-2-carboxylic acid is an indolyl carboxylic acid.

Highly potent and selective non-competitive antagonist acting at the strychnine-insensitive glycine binding site of the NMDA receptor-channel complex (K d = 0.8 nM). Displays > 1000-fold selectivity over NMDA, AMPA and kainate binding sites. Orally bioavailable and active in vivo .

A poison by intravenous route. When heated to decomposition it emits toxic vapors of NOx and Cl-.
