ABSTRACT:
Compounds of the formula ##STR1## in which R.sub.1 represents hydrogen or acyl, A represents an optionally N-alkylated .alpha.-amino acid residue which is bonded N-terminally to R.sub.1 and C-terminally to the group --NR.sub.2 --, R.sub.2 represents hydrogen or lower alkyl, R.sub.3 represents hydrogen, lower alkyl, optionally etherified or esterified hydroxy-lower alkyl, cycloalkyl, cycloalkyl-lower alkyl, bicycloalkyl-lower alkyl, tricycloalkyl-lower alkyl, aryl or aryl-lower alkyl, R.sub.4 represents hydroxy or etherified or esterified hydroxy, R.sub.5 represents lower alkyl having 2 or more carbon atoms, optionally etherified or esterified hydroxy-lower alkyl, cycloalkyl, cycloalkyl-lower alkyl, bicycloalkyl, bicycloalkyl-lower alkyl, tricycloalkyl, tricycloalkyl-lower alkyl, aryl, aryl-lower alkyl, optionally substituted carbamoyl, optionally substituted amino, optionally substituted hydroxy or optionally substituted mercapto and R.sub.6 represents substituted amino, and salts of such compounds having salt-forming groups inhibit the blood pressure-increasing action of the enzyme renin and can be used as antihypertensives.
