A compound of the formula: ##STR1## wherein R.sup.1 is H or an optionally substituted hydrocarbon or acyl group; ring A is an optionally further substituted benzene ring; n is an integer of 1 to 10; R.sup.2, R.sup.3 and R.sup.4 are H or an optionally substituted hydrocarbon group; R.sup.3 and R.sup.4 may form an optionally substituted heterocyclic group, taken together with the adjacent nitrogen atom; k is an integer of 0 to 3; and m is an integer of 1 to 8; provided that when k=0 and m=2, n is an integer of not less than 2 or a pharmaceutically acceptable salt thereof, exhibiting excellent cholinesterase inhibitory activity and monoamine reuptake inhibitory activity, thus being useful as therapeutic/prophylactic medicaments of senile dementia.
该化合物的分子式为:##STR1##其中R.sup.1为H或可选择取代的烃基或酰基;环A为可选择进一步取代的苯环;n为1到10的整数;R.sup.2、R.sup.3和R.sup.4为H或可选择取代的烃基;R.sup.3和R.sup.4可以与相邻的氮原子一起形成可选择取代的杂环基;k为0到3的整数;m为1到8的整数;但当k=0且m=2时,n为不少于2的整数或其药学上可接受的盐,表现出优异的胆碱酯酶抑制活性和单胺再摄取抑制活性,因此可用作治疗/预防老年性痴呆的药物。
