Syntheses of a series of enantiomericallypure, substituted analogues 7b–t of SDZEAB515 (7a) were described (Schemes 1 and 2). Affinites for the NMDA receptor were measured ([3H]CGP-39653 binding assay) and competitive NMDA antagonistic potencies determined in a functional test (rat neocortical slice preparation). Structure-activity relationships show that attachment of an OH group at position 4

R-configuration by being able to use a neutral amino acid uptake system to enhance both peripheral adsorption and transport into the brain. Examination in a system L neutral amino acid transport carrier assay shows that 1 competes with L-Phe for transport in an apparent competitive and stereospecific manner (estimated Ki = 50 microM). The 1- and 2-naphthyl derivatives 3a,3b were found to be among the most potent
