The invention relates to novel substituted tyrosyl alanine dipeptide amides of the formula: ##STR1## and the pharmaceutically acceptable acid addition salts thereof wherein R.sup.1 is hydrogen, lower alkyl, hydroxy, lower alkoxy, --O(CH.sub.2).sub.n phenyl with the phenyl optionally substituted by halogen, --NO.sub.2, --CN, --NH.sub.2 or lower alkyl wherein n is 1 to 4; R.sup.2 and R.sup.3 represent lower alkyl, halogen, or lower alkoxy, or either one of R.sup.2 or R.sup.3 is hydrogen and the other is lower alkyl, lower alkoxy or halogen; R.sup.4, R.sup.5, R.sup.6, and R.sup.9 may be the same or different and represent hydrogen, lower alkyl, cycloalkyl having 3 to 8 carbons, unsaturated lower alkyl, or --(CH.sub.2).sub.m cycloalkyl with the cycloalkyl having 3 to 8 carbons and m is 1 to 4; R.sup.10 is hydrogen or --(CH.sub.2).sub.p phenyl or with the phenyl optionally substituted with --NH.sub.2, --OH, halogen, --NO.sub.2, or lower alkyl or --(CH.sub.2).sub.p thienyl wherein p is 1 to 4; one of R.sup.7 or R.sup.8 is --(CH.sub.2).sub.f --S(O).sub.z --(CH.sub.2).sub.q --CH.sub.3 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 R.sup.7 and R.sup.8 together with carbon w is ##STR2## 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 R.sup.7 and R.sup.8 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.
