Abstract

The synthesis and initial SAR studies of novel, highly potent positive allosteric modulators of AMPA receptors based on 3-(4-tert-butylphenyl)-4-cyano-5-methylsulfanyl-thiophene-2-carboxylic acid (6a) are described. SAR studies at the thioether moiety indicated that substitution at this position was mandatory and better potency was achieved with small groups.
