摘要

Compounds of formula I, <CHEM> wherein A represents C=C, S or O; Q represents a 5- or 6-membered unsaturated heterocyclic ring having a nitrogen atom in the position adjacent to the point of attachment, 0-3 further heteroatoms selected from N, O and S, and substituents R6 and R7; R<1> represents H or C<5> PI 1/4 alkyl; R<2> represents H, C<5> PI 1/4 alkyl, C<7> PI 1/4 alkenyl, C<7> PI 1/4 alkynyl, C<7> PI 1/4 cycloalkyl or NH<6>CH<6>CO-; in addition, R<1> and R<2> taken together may form a C<7> PI psi alkylene chain; R<3> represents H, C<5> PI 1/4 alkyl, C<7> PI 1/4 alkenyl, C<7> PI 1/4 alkynyl; R4 and R5 independently represent H, OH, C<5> PI 1/4 alkoxy, C<5> PI 1/4 alkyl, halogen, trifluoromethyl or NR8R9; R6 and R7 independently represent H, OH, C<5> PI 1/4 alkoxy, C<5> PI 1/4 alkyl, halogen, trifluoromethyl, C<5> PI 1/4 hydroxyalkyl, amidino, CONH<6> or NR8R9; in addition, R6 and R7 may independently represent O when substituted on N; R8 and R9 independently represent H or C<5> PI 1/4 alkyl; with various provisos; and pharmaceutically acceptable derivatives thereof; are useful as pharmaceuticals, in particular in the treatment of neurological disorders.
