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, --OCO.sub.2 lower alkyl, 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, R.sup.7, R.sup.8, and R.sup.9 may be the same or different and represent hydrogen or lower alkyl; R.sup.10 is selected from the group consisting of --(ALK)X where ALK represents alkylene, thioalkylene, oxyalkylene, having 1 to 5 carbon atoms; alkenylene and alkynylene having 2 to 4 carbon atoms; and X represents pyridyl, pyrimidinyl, 9H-fluoren-9-yl, diphenylmethyl, thienyl, carboxy, lower alkoxy carbonyl, substituted phenyl wherein the phenyl substituent is amino, hydroxy, halogen, nitro, methylenedioxy, lower alkyl, carboxy, lower alkoxycarbonyl, lower alkoxy, carboxamide, diloweralkylamino or X represents phenyl, when ALK is not alkylene; or R.sup.10 is ##STR2## where p and q are independently 1 to 4; or R.sup.9 and R.sup.10 together with N is ##STR3## where r and t are independently 1 to 4; v represents an asymmetric carbon that may be racemic 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 racemic or have the D or L configuration. These compounds are useful as analgesic and/or antihypertensive compounds.
该发明涉及以下结构的新型取代酪氨酸丙氨酸二肽酰胺:##STR1##及其药学上可接受的酸盐,其中R.sup.1为氢、较低的烷基、羟基、--OCO.sub.2较低的烷基、较低的烷氧基、--O(CH.sub.2).sub.n-苯基,其中苯基可选择地被卤素、--NO.sub.2、--CN、--NH.sub.2或较低的烷基取代,其中n为1至4;R.sup.2和R.sup.3代表较低的烷基、卤素或较低的烷氧基,或者R.sup.2或R.sup.3中的一个为氢,另一个为较低的烷基、较低的烷氧基或卤素;R.sup.4、R.sup.5、R.sup.6、R.sup.7、R.sup.8和R.sup.9可以相同也可以不同,代表氢或较低的烷基;R.sup.10从以下组中选择:--(ALK)X,其中ALK代表具有1至5个碳原子的烷基、硫代烷基、氧代烷基;具有2至4个碳原子的烯基和炔基;X代表吡啶基、嘧啶基、9H-芴-9-基、二苯甲基、噻吩基、羧基、较低的烷氧基羰基、取代的苯基,其中苯基取代基为氨基、羟基、卤素、硝基、亚甲二氧基、较低的烷基、羧基、较低的烷氧羰基、较低的烷氧基、羧酰胺、二较低烷基氨基或X代表苯基,当ALK不是烷基时;或R.sup.10为##STR2##其中p和q独立地为1至4;或R.sup.9和R.sup.10与N一起为##STR3##其中r和t独立地为1至4;v代表可能是消旋的或具有D或L构型的不对称碳;w代表当R.sup.7和R.sup.8不相同时可能是消旋的或具有D或L构型的不对称碳。这些化合物可用作镇痛和/或降压化合物。
