Acylglycinamides as inhibitors of glycine transporter type 1

A screening hit was used as the basis for the core structure of a new series of acylglycinamide GlyT-1 inhibitors. Investigation of the SAR around four areas of diversity used facile chemistry to prepare compounds quickly. By focussing on reducing the lipophilicity and improving the aqueous solubility in the series we were able to prepare a compound (17e) with a good level of activity at GlyT-1, selectivity over GlyT-2 and moderate oral bioavailability.
