title: Synthesis and AMPA receptor antagonistic activity of a novel class of quinoxalinecarboxylic acid with a substituted phenyl group at the C-7 position.
abstract: The synthesis and biological properties of a novel class of 7-heterocycle-substituted quinoxalinecarboxylic acids, which bear a substituted phenyl group through a urethane linkage at the C-7 position, are described. One of the synthesized compounds, 15l, which has a 4-carboxyphenyl carbamoyloxymethyl imidazole group at the C-7 position and is water-soluble, was found to possess high potency in vitro and showed excellent neuroprotective efficacy in vivo.
