New derivatives of D,L-glutamic acid and D,L-aspartic acid are described having the formulae: ##STR1## in which n is equal to 1 or 2, R.sub.1 is a phenyl group mono-, di- or tri-substituted with linear or branched C.sub.1 -C.sub.4 alkyl groups, which may be the same or different, or with halogens, with a cyano group or a trifluoromethyl group, and in which R.sub.2 is selected from the group consisting of morpholino, piperidino and amino with one or two linear, branched or cyclic alkyl group substituents containing from 1 to 8 carbon atoms, which may be the same or different, or a pharmaceutically-acceptable salt thereof. The compounds have an antagonistic activity towards bioactive polypeptides and are useful particularly in the treatment of illnesses of the digestive system and the central nervous system, as pain killers, and for the treatment of anorexia and all those affections (for example tumours) in which exogenous or endogenous bioactive polypeptides are involved.
本文描述了D,L-谷氨酸和D,L-天冬氨酸的新衍生物,其化学式为:##STR1## 其中n等于1或2,R.sub.1是苯基单、双或三取代的线性或支链C.sub.1-C.sub.4烷基,可以是相同或不同的,或取代有卤素、氰基或三氟甲基基团;R.sub.2选自吗啡啶、哌啶和含有1至8个碳原子的一种或两种线性、支链或环状烷基取代物的氨基,可以是相同或不同的,或其药学可接受的盐。这些化合物对生物活性多肽具有拮抗活性,特别适用于治疗消化系统和中枢神经系统的疾病、作为止痛药、以及治疗厌食症和那些涉及内源性或外源性生物活性多肽的疾病(例如肿瘤)。
