This application is a 371 of PCT/JP96/00796 filed Mar. 27, 1996.
TECHNICAL FIELD
The present invention relates to new piperidine derivatives having an antagonism on Substance P, being a peptide neurotransmitter, and pharmaceutically acceptable acid addition salts thereof. The piperidine derivatives
The present invention relates to certain benzoamide piperidine containing compounds and related compounds that exhibit activity as NK-1 receptor antagonists, (e.g., substance P receptor antagonists), to pharmaceutical compositions containing them, and to their use in the treatment and prevention of
SUMMARY OF THE INVENTION
According to one aspect of our invention, we provide compounds of the general formula ##STR1## wherein R represents a halogen atom or a hydroxy, lower alkoxy, lower alkenyloxy, lower alkynyloxy or aralkyloxy (preferably a phenyl(lower)alkyloxy, e.g. benzyloxy) group, or a
BACKGROUND OF THE INVENTION
Dopamine, norepinephrine and serotonin are mammalian monoamine neurotransmitters that play important roles in a wide variety of physiological processes. Therefore, compounds that selectively modulate the activity of these three neurotransmitters, either individually, in
