摘要:
A compound which is a piperidine derivative of formula (I) ##STR1## in which R represents hydrogen, or unbranched or branched C.sub.1 -C.sub.6 alkyl group; andAr represents phenyl optionally substituted with one or more radicals selected from the halogens, amino, C.sub.1 -C.sub.2 alkoxy and (C.sub.3 -C.sub.6)cycloalkyl(C.sub.1 -C.sub.2)alkoxy, or a heteroaryl group;or a pharmaceutically acceptable acid addition salt thereof;provided that when R is hydrogen Ar is not phenyl or 4 -chlorophenyl.The compounds are useful in therapy as ligands for 5-HT.sub.3 and 5-HT.sub.4 receptors.
摘要:
A compound which is a piperidine derivative of general formula (I) ##STR1## in which R.sub.1 represents a hydrogen atom, a linear or branched (C.sub.1-6)alkyl group or a cyclo(C.sub.3-8)alkyl group, X represents an oxygen atom, a sulphur atom or a group of general formula N--R.sub.3 in which R.sub.3 is a hydrogen atom, or a linear or branched (C.sub.1-8)alkyl, cyclo(C.sub.3-6)alkyl, cyclo(C.sub.3-6)alkylmethyl, (C.sub.1-4)alkoxy-(C.sub.1-4)alkyl, phenyl, pyridin-4-yl, pyridin-3-yl, pyridin-4-ylmethyl or pyridin-3-ylmethyl group and Z represents a hydrogen or fluorine atom and acid addition salts thereof with pharmaceutically acceptable acids, can be used for the treatment and prevention of disorders in which 5-HT receptors are involved.
