Compounds of formula (I): ##STR1## A is a carbon-carbon bond or C.sub.1 -C.sub.3 alkylene; B is imino group or C.sub.1 -C.sub.2 alkylene; R.sup.1 is C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, heterocyclic or optionally substituted amino; R.sup.2 is optionally substituted phenyl or optionally substituted naphthyl; R.sup.3 is thiazolyl, isoxazolyl or imidazolyl; R.sup.4 is isopropyl or cyclohexyl; R.sup.5 and R.sup.6 are C.sub.1 -C.sub.4 alkyl, or, together with the carbon atom to which they are attached, C.sub.3 -C.sub.7 cycloalkyl; R.sup.7 is hydrogen, optionally substituted C.sub.1 -C.sub.6 alkyl group; and R.sup.8 is hydrogen or C.sub.1 -C.sub.4 alkyl. These compounds have renin-inhibitory and, hence, hypotensive activities. The invention also provides a method for the treatment or prophylaxis of hypertension induced by failures in the renin-angiotensin system.
