Abstract
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 1 , R 3 and R 5 are loweralkyl or hydrophilic, lipophilic or aromatic amino acid side chains and may be the same or different; R 2 , R 4 , R 7 , R 8 and R 9 are hydrogen or loweralkyl and may be the same or different; X is NH, O, S, SO or SO 2 ; and R 6 is loweralkyl, cycloalkyl, cycloalkylalkyl, aryl, arylalkyl or an N-protecting group, with the proviso that R 6 may be an N-protecting group when X is NH.
