Muscimol and N,N-dimethylmuscimol: From a GABA agonist to a glycine antagonist
By using molecular modeling methods, a molecular mechanism was identified which can explain how the incorporation of two methyl groups in place of two hydrogen atoms on the terminal nitrogen atom of muscimol can not only convert this potent agonist at GABAnergic receptors to an inactive molecule at...

Zusammenfassung: | By using molecular modeling methods, a molecular mechanism was identified which can explain how the incorporation of two methyl groups in place of two hydrogen atoms on the terminal nitrogen atom of muscimol can not only convert this potent agonist at GABAnergic receptors to an inactive molecule at these receptors, but also can convert this new derivative to an antagonist of glycine at glycinergic receptors. This insight into the molecular mechanism operative in the conversion of physiological function provides a basis for understanding how a single molecule may be able to act at both the GABA‐ and glycine‐inhibitory receptors. |
