Abstract:
:Several optically active N-(indol-3-ylglyoxylyl)amino acid derivatives were synthesized and tested for [3H]flunitrazepam displacing activity in bovine brain membranes. IC50 values were measured and revealed that the D form of the amino acid moiety of the compounds was more potent than both the L form and racemic form, suggesting a key role of the amino acid stereochemistry on the affinity to the benzodiazepine receptors. GABA ratio and proconvulsant/convulsant data reported for the most active compounds reveal they behave as inverse agonists at the benzodiazepine receptor.
