Discovery of non-zwitterionic GABA(A) receptor full agonists and a superagonist.
Numerous previous studies of GABA(A) receptor ligands have suggested that GABA(A) receptor agonists must be zwitterionic and feature an intercharge separation similar to that of GABA (approx. 4.7-6A). In this communication we demonstrate that appropriately functionalized GABA amides are partial, full, or superagonists, despite their non-zwitterionic structure.
