Abstract
There are described new compounds of formula (1) ##STR1## wherein R.sup.1 represents an acyl group; PA1 X.sup.1 represents phenylalanine or p-methoxyphenylalanine bonded N-terminally to R.sup.1 and C-terminally to X.sup.2 ; PA1 X.sup.2 represents histidine or N-methylhistidine bonded N-terminally to X.sup.1 and C-terminally to the group --NH--; PA1 R.sup.2 represents a C.sub.4-6 cycloalkyl group; PA1 R.sup.3 represents a group CHR.sup.6 R.sup.7 is a hydrogen atom and R.sup.7 is a phenyl group, or R.sup.6 is a methyl group and R.sup.7 is a hydrogen atom or a methyl or ethyl group; PA1 X.sup.3 represents a C.sub.2-6 alkylene chain optionally substituted by one or more C.sub.1-4 alkyl groups; PA1 R.sup.4 and R.sup.5, which may be the same or different, each independently represent a hydrogen atom or a C.sub.1-4 alkyl group, or NR.sup.4 R.sup.5 may form a 5- or 6- membered polymethylenimine ring; PA1 and salts and solvates thereof. The new compounds have been found to exhibit activity as renin inhibitors, combining good duration of action with significant oral potency. Compositions containing the compounds of formula (1) and processes for preparing the compounds are also described.
