The invention relates to novel substituted tyrosyl alanine dipeptide amides of the formula: ##STR1## and the pharmaceutically acceptable acid addition salts thereof wherein R.sub.1 represents straight or branched lower alkyl having 1 to 4 carbons; R.sub.2 represents hydrogen, hydroxy, --OCO.sub.2 R.sub.1 substituent or lower alkyl having 1 to 4 carbons; R.sub.3 represents a hydrogen or lower alkyl having 1 to 6 carbons; R.sub.4 and R.sub.5 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 OCO.sub.2 R.sub.1 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 R.sub.4 and R.sub.5 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.
该发明涉及一种新颖的取代酪氨酸丙氨酸二肽酰胺,其化学式为:##STR1##及其药用可接受的酸盐,其中R.sub.1代表直链或支链低碳1到4的烷基;R.sub.2代表氢、羟基、--OCO.sub.2 R.sub.1取代基或1到4碳的低碳烷基;R.sub.3代表氢或1到6碳的低碳烷基;R.sub.4和R.sub.5可以相同也可以不同,代表氢或1到6碳的低碳烷基;n为1到6;X代表氢、羟基或OCO.sub.2 R.sub.1取代基;A代表环己基、苯基或苯基,其上有一个或多个含1到6碳的低碳烷基、一个或多个氨基、羟基、卤素、硝基或1到6碳的低碳烷氧基取代基;V代表可能是外消旋或具有D或L构型的不对称碳;W代表当R.sub.4和R.sub.5不相同时的不对称碳,可能是外消旋或具有D或L构型。这些化合物可用作镇痛和/或降压剂。
