The invention relates to novel substituted tyrosyl alanine dipeptide amides of the formula:
and the pharmaceutically acceptable acid addition salts thereof wherein
R, represents straight or branched lower alkyl having 1 to 4 carbons;
R2 represent hydrogen, hydroxy, -OCO2R1 substituent or lower alkyl having 1 to 4 carbons;
R3 represents a hydrogen or lower alkyl having 1 to 6 carbons;
R4 and R5 may be the same or different and represent hydrogen or lower alkyl having 1 to 6 carbons;
n is 1 to 6;
X represents a hydrogen, hydroxy or OCO2R1 substituent;
A represents a cyclohexyl, phenyl or phenyl substituted with one or more lower alkyls containing 1 to 6 carbons, one or more amino, hydroxy, halogen, nitro or lower alkoxy substituent having 1 to 6 carbons;
V represents the asymmetric carbon that may be racemic or have the D or L configuration;
W represents the asymmetric carbon when R4 and R5 are not the same that may optionally be racemic or have the D or L configuration. These compounds are useful as analgesic and/or antihypertensive agents.
