The invention provides compounds of the formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3, which can be the same or different, are each hydrogen, chloro, bromo, fluoro, methyl, ethyl, methoxy, amino, hydroxy or nitro; R.sub.4 is hydrogen or alkyl of 1 to 7 carbon atoms; --X-- is ##STR2## R.sub.5 is hydrogen, hydroxy or --OR.sub.6 ; and R.sub.6 is alkyl of 1 to 7 carbon atoms or aryl of 6 to 10 carbon atoms; and their non-toxic pharmaceutically acceptable acid addition salts and mixtures thereof. Processes for the preparation and use of the subject compounds are described, as are novel pharmaceutical compositions comprising at least one of the subject compounds or their salts. The compounds and their non-toxic salts exhibit valuable pharmacological activity and are useful in the treatment of mammals, e.g., as anti-ulcer or anti-hypertensive agents. Furthermore, they are useful as diuretic, sedative, analgesic, anti-inflammatory and tranquilizing agents.
本发明提供的化合物的公式为:##STR1## 其中R.sub.1,R.sub.2和R.sub.3可以相同也可以不同,分别为氢、氯、溴、氟、甲基、乙基、甲氧基、氨基、羟基或硝基;R.sub.4为氢或1至7个碳原子的烷基;--X--为##STR2## R.sub.5为氢、羟基或--OR.sub.6;R.sub.6为1至7个碳原子的烷基或6至10个碳原子的芳基;以及它们的非毒性医药上可接受的酸盐和混合物。本发明还描述了制备主题化合物的方法,以及包含至少一种主题化合物或其盐的新型药物组合物。这些化合物及其非毒性盐表现出有价值的药理活性,并且可用于哺乳动物的治疗,例如作为抗溃疡或降压剂。此外,它们还可用作利尿剂、镇静剂、镇痛剂、抗炎剂和镇定剂。
