Abstract:
A renin inhibiting compound of the formula: wherein A is a functional group; W is
(1) -C(O)-, (2) -CH(OH)- or (3) -N(R₂)- wherein R₂ is hydrogen or loweralkyl; U is
(1) -C(O)-, (2) -CH₂- or (3) -N(R₂)- wherein R₂ is hydrogen or lower alkyl, with the proviso that when W is -CH(OH)- then U is -CH₂- and with the proviso that U is -C(O)- or -CH₂- when W is -N(R₂)-; V is
(1) -CH-, (2) -C(OH)- or (3) -C(halogen)- with the proviso that v is -CH-when U is -N(R₂)-; Q is -CH(R₁)- or -C(=CHR 1a )- wherein R₁ is
(1) loweralkyl, (2) cycloalkylalkyl, (3) arylalkyl, (4) (heterocyclic)alkyl, (5) 1-benzyloxyethyl, (6) phenoxy, (7) thiophenoxy or (8) anilino, provided that B is -CH₂- or -CH(OH)- or A is hydrogen when R₁ is phenoxy, thiophenoxy or anilino and R 1a is aryl or heterocyclic; R₃ is a functional group; R₄ is
(1) loweralkyl, (2) cycloalkylmethyl or (3) benzyl; R₅ is -CH(OH)- or -C(O)-; R₆ is -CH(OH)- or -C(O)-; and Z is
(1) lower alkyl, (2) aryl, (3) arylalkyl, (4) cycloalkyl, (5) cycloalkylalkyl, (6) heterocyclic or (7) (heterocyclic)alkyl; or a pharmaceutically acceptable salt, ester or prodrug thereof.
Abstract:
