DERIVATIVES OF 4-HYDROXYBUTANOIC ACID AND OF ITS HIGHER HOMOLOGUE AS LIGANDS OF GAMMA-HYDROXYBUTYRATE (GHB) RECEPTORS, PHARMACEUTICAL COMPOSITIONS CONTAINING SAME AND PHARMACEUTICAL USES

摘要

The invention concerns the field of synthesis organic chemistry applied to the pharmaceutical field and concerns novel derivatives of 4-hydroxybutanoic acid and its higher homologue, 5-hydroxypentanoic acid, their crotonic homologues, pharmaceutical compositions containing them and their pharmaceutical uses. Said novel derivatives are capable of binding with gamma-hydroxybutyrate (GHB)-specific receptors and hence capable of exhibiting agonist or antagonist properties, in particular for treating sleep disorders, anxiety and general diseases of the central nervous system. The invention also concerns compounds of general formula (I) wherein the substituents are as defined in the description.
