The compounds of the formula ##STR1## wherein R signifies halogen or lower alkyl; n signifies 0-3; R.sup.1 signifies lower alkyl; cycloalkyl; benzyl optionally substituted by hydroxy, halogen, lower alkoxy or lower alkyl; benzoyl optionally substituted by amino, lower alkyl-amino or di-lower alkylamino; acetyl or cycloalkyl-carbonyl; and ##STR2## signifies an aromatic 5-membered residue which is bonded via a N-atom and which contains further 1-3 N atoms in addition to the linking N atom, as well as their pharmaceutically acceptable salts as therapeutically active substances, especially for the control or prevention of acute and/or chronic neurological disorders.
Heterocyclic enol ethers of type 1 were studied with respect to the inhibition of 1S,3R-ACPD (10 mu M)stimulated GTP gamma(35)S binding on rat mGluR2 transfected cell membranes. The structure activity relationship with regard to the substitution pattern of the phenyl ring, the oxygen substituent and the nature of the heterocycle is discussed, (C) 1999 Elsevier Science Ltd.
