The invention relates to novel substituted tyrosyl alanine dipeptide amides of the formula:
and the pharmaceutically acceptable acid addition salts thereof wherein R¹ is hydrogen, lower alkyl, hydroxy, lower alkoxy, -O(CH₂)nphenyl with the phenyl optionally substituted by halogen, -NO₂, -CN, -NH₂ or lower alkyl wherein n is 1 to 4; R² and R³ represent lower alkyl, halogen, or lower alkoxy, or either one of R² or R³ is hydrogen and the other is lower alkyl, lower alkoxy or halogen; R⁴, R⁵, R⁶, and R⁹ may be the same or different and represent hydrogen, lower alkyl, cycloalkyl having 3 to 8 carbons, unsaturated lower alkyl, or -(CH₂)mcycloalkyl with the cycloalkyl having 3 to 8 carbons and m is 1 to 4; R10 is hydrogen or -(CH₂)pphenyl or with the phenyl optionally substituted with -NH₂, -OH, halogen, -NO₂, or lower alkyl or -(CH₂)p thienyl wherein p is 1 to 4; one of R⁷ or R⁸ is -(CH₂)f-S(O)z-(CH₂)q-CH₃ where f is 1 to 3 and q is 0 to 3, z is 0, 1 or 2 and the other is hydrogen or lower alkyl, or R⁷ and R⁸ together with carbon w is
where x and y are independently 1 to 3 and z is 0, or 2. V represents an asymmetric carbon that may be recemic or have the D or L configuration; W represents an asymmetric carbon when R⁷ and R⁸ are not the same that may be recemic or have the D or L configuration.
The compounds of this invention are useful as analgesic and/or antihypertensive agents.
