The invention concerns novel renin-inhibitory peptides which are useful for treating renin-assocated hypertension, hyperaldosteronism, and congestive heart failure. Processes for preparing the peptides, compositions containing them and methods of using them are included. Also included is a diagnostic method which uses the compounds to determine the presence of renin-associated hypertension or hyperaldosteronism.

Compounds of formula (I):
(wherein m is 0 or 1 and R1-R5 are a variety of organic groups) have the ability to inhibit the activity of renin and may thus be used to treat hypertension induced by failures in the renin-angiotensin system. They are prepared by conventional peptide synthesis routes.
