Carboxyalkyl substituted inhibitors of enkephalinase and ACE.

摘要

The present invention relates to compounds of the formula <CHEM> wherein B<5> and B<6> are each independently hydrogen; hydroxy; -OR<6> wherein R<6> is a C<5>-C<8> alkyl or an Ar-Y group wherein Ar is aryl and Y is a hydrogen or C<5>-C<8> alkyl; or, where B<5> and B<6> are attached to adjacent carbon atoms, B<5> and B<6> can be taken together with said adjacent carbons to form a benzene ring or methylenedioxy; A is a bond, methylene or oxygen, sulfur or NR<8> or NCOR psi wherein R<8> is hydrogen, a C<5>-C<8> alkyl or an Ar-Y- group and R psi is -CF<7>, a C<5>-C<5><4> alkyl or an Ar-Y- group; R<7> is hydrogen or -CH<6>OC(O)C(CH<7>)<7>; R<5> is hydrogen, C<5>-C<8> alkyl or -CH<6>OC(O)-C(CH<7>)<7>; and n is an integer 1 to 3, which are useful as inhibitors of enkephalinase and ACE.
