A structure-activity relationship (SAR) study of kaitocephalin (KCP), known to be a potent naturally occurring NMDA receptor ligand, was performed. This study led us to the discovery of (7S)-kaitocephalin as a highly selective NMDA receptor ligand. It displayed a 22-fold higher degree of selectivity for the NMDA receptor over KCP, though the binding affinity of (7S)-KCP [Ki = 29 nM] was 3.7-fold less potent than that of KCP [Ki = 7.8 nM].
