The invention relates to new NR2B selective NMDA receptor antagonist carboxylic acid amide derivatives of formula (I) as well as the recemates, optical antipodes and the salts thereof formed with acids and bases. Fruthermore objets of the present invention are the pharmaceutical compositions containing compounds of formula (I) or the salts thereof as active ingredients, as well as the synthesis of compounds of formula (I), and the chemical and pharmaceutical manufacture of medicaments containing these compounds, as well as the method of treatments with these compounds, which means administering to a mammal to be treated - including human - effective amount/amounts of compounds of formula (I) of the present invention as such or as medicament. The new carboxylic acid amide derivatives of formula (I) of the present invention are highly effective and selective antagonists of NMDA receptor, and moreover most of the compounds are selective antagonist of NR2B subtype of NMDA receptor.

A novel series of indole-2-carboxamide derivatives was prepared and identified as NR2B selective NMDA receptor antagonists. The influence of the number and position of OH groups on the indole skeleton as well as the substitution of the piperidine ring on the biological activity of the compounds was studied.
