ABSTRACT:
The invention relates to renin inhibiting compounds of the formula ##STR1## wherein A is an N-protecting group; n is 0 or 1; B is hydrogen, hydroxy, NH, loweralkyl or arylalkyl; with the proviso that when A is an N-protecting group, B is NH and when n is 0, B is hydrogen, hydroxy, loweralkyl or arylalkyl; R.sub.1, R.sub.3 and R.sub.5 are loweralkyl or hydrophilic, lipophilic or aromatic amino acid side chains and may be the same or different; R.sub.2, R.sub.4, R.sub.7, R.sub.8 and R.sub.9 are hydrogen or loweralkyl and may be the same or different; X is NH, O, S, SO or SO.sub.2 ; and R.sub.6 is loweralkyl, cycloalkyl, cycloalkylalkyl, aryl, arylalkyl or an N-protecting group, with the proviso that R.sub.6 may be an N-protecting group when X is NH.
