There are disclosed compounds of the formula ##STR1## wherein R is hydrogen, halo or trifluoromethyl; R.sup.1 is hydrogen or X; R.sup.2 is hydrogen or X; with the proviso that when R.sup.1 is X, R.sup.2 is hydrogen, and when R.sup.1 is hydrogen, R.sup.2 is X; X is the moiety ##STR2## wherein R.sup.3 is hydrogen or lower alkyl; R.sup.4 is hydrogen or ##STR3## R.sup.5 is hydrogen, alkyl of 1-16 carbon atoms, phenyl, phenylloweralkyl or perfluoroloweralkyl; Y is CO or a bond; R.sup.6 is lower alkyl, cycloloweralkyl, arylalkyl, --(CH.sub.2).sub.m -cycloloweralkyl, ##STR4## or --(CH.sub.2).sub.o CONR.sup.8 R.sup.9 or, in the case when Y is CO, phenyl; R.sup.7 is hydrogen or ##STR5## R.sup.8 and R.sup.9 are, independently, hydrogen, lower alkyl, cycloloweralkyl or R.sup.8 and R.sup.9 together with the nitrogen atom to which they are attached form a 5-8 membered saturated monoazacyclic ring; m is 1-3; n is 1-3; o is 1-10; and the pharmacologically acceptable salts thereof and, which by virtue of their ability to antagonize bradykinin, are analgesic agents useful in the treatment and management of pain.
揭示了以下化合物的结构式:其中R为氢、卤素或三氟甲基;R.sup.1为氢或X;R.sup.2为氢或X;但当R.sup.1为X时,R.sup.2为氢,当R.sup.1为氢时,R.sup.2为X;X是结构单元:其中R.sup.3为氢或较低烷基;R.sup.4为氢或;R.sup.5为氢、1-16碳原子的烷基、苯基、苯基较低烷基或全氟较低烷基;Y为CO或键;R.sup.6为较低烷基、环较低烷基、芳基烷基、--(CH.sub.2).sub.m -环较低烷基、或 --(CH.sub.2).sub.o CONR.sup.8 R.sup.9或在Y为CO时为苯基;R.sup.7为氢或;R.sup.8和R.sup.9独立地为氢、较低烷基、环较低烷基或R.sup.8和R.sup.9与它们连接的氮原子形成5-8成员饱和的单环氮杂环;m为1-3;n为1-3;o为1-10;以及其药理学上可接受的盐,由于它们拥有对抗激肽酶的能力,因此是用于治疗和管理疼痛的镇痛剂。
