ABSTRACT:
A novel compound of the formula: ##STR1## wherein Ar represents an optionally substituted tricyclic condensed benzene ring group which includes at least one heterocyclic ring as a component ring; n represents an integer from 2 to 10; R.sup.1 represents H or an optionally substituted hydrocarbon group, which may be different from one another in the repetition of n; and Y represents an optionally substituted 4-piperidinyl, 1-piperazinyl or 4-benzyl-1-piperidinyl group, or a salt thereof, inhibiting excellent cholinesterase inhibitory activity and monoamine reuptake inhibitory activity, thus being useful as therapeutic and/or prophylactic medicaments of senile dementia.
