Blocking the interaction between the Gβγprotein and the glycine receptor (GlyR) has emerged as a promising pharmacological strategy to treat acute alcohol intoxication by inhibiting ethanol potentiation on GlyR. M554 is a recently discovered small molecule capable of binding to Gβγwith potent in vitro and in vivo inhibitory activity. This compound has been tested as a mixture of diastereomers, and no information is available concerning the stereospecific activity of each species, which is critical to pursue efforts on lead optimization and drug development. In this work, we explored the differential activity of four M554 stereoisomers by in silico molecular dynamics simulations and electrophysiological experiments. Our results revealed that the (R,R)-M554 stereoisomer is a promising lead compound that inhibits ethanol potentiation of GlyR.
