  • Patent number: 5132400
    Abstract: The present invention provides novel peptides of the formula X-A.sub.6 -B.sub.7 -C.sub.8 -D.sub.9 -E.sub.10 -F.sub.11 containing a novel (1-amino-2-hydroxy-2-heterocyclic) ethyl moiety of the formula XL.sub.2c at the E.sub.10 -F.sub.11 -position, X is a terminal group, and the remaining variables are amino acid residues. The present invention also provides novel intermediate compounds. These peptides are useful as renin inhibitors and as inhibitors of retroviral proteases. Renin inhibitors are useful for the diagnosis and control of renin-dependent hyperaldosterism, other renin-dependent cardiovascular disorders and ocular disorders. Inhibitors of retroviral proteases, such as the HIV-I protease, are useful for treating diseases caused by retroviruses, such as human acquired immunodificiency disease syndrome (AIDS).
