Abstract
(RS)-4-Amino-3-(4-chlorophenyl)butanoic acid (baclofen, 2) is the prototypic selective GABABR agonist and is used clinically for the treatment of spasticity associated with brain and spinal cord injuries. Synthesis and GABAB receptor agonist activity of certain amino acids structurally related to baclofen (2) are reported. (RS)-4-amino-3-(4- ethynylphenyl)butanoic acid hydrochloride (1b) showed GABAB receptor agonist activity with EC50 = 240 μM whereas (RS)-4-amino-3-(4-iodophenyl)butanoic acid hydrochloride (1c) emerged as the best GABAB receptor agonist congener in the synthesized compounds with ED50 = 32 μM.
