    摘要: A phenylpiperazine derivative according to the present invention has the following general formula [I]: ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are independently hydrogen or alkoxy group having 1 to 3 carbon atoms, orR.sup.1 and R.sup.2 or R.sup.2 and R.sup.3 together with carbon atoms to which they are attached form --O(CH.sub.2).sub.m O-- wherein m is an integer of 1 to 3, oreither R.sup.1 or R.sup.2 is amine residue selected from the group consisting of --NH.sub.2 , --NHSO.sub.2 CH.sub.3, --NHCOCH.sub.3 and --NHCONH.sub.2 and the other is hydrogen or alkoxy group of 1 to 3 carbon atoms and R.sup.3 is hydrogen;R.sup.4 and R.sup.5 are independently hydrogen or alkyl group of 1 to 3 carbon atoms;Y is --CO-- or --SO.sub.2 -- provided that at least one of R.sup.1 and R.sup.2 is not hydrogen when Y is --CO--; andn is an integer of 2 to 4.An acid addition salt of the phenylpiperazine derivative having the general formula [I] is included in the present invention. The phenylpiperazine derivative as well as its acid addition salt according to the present invention have the ability to reduce the blood pressure.
