2-Substituted-5-oxo-5H-dibenzo[a,d]cycloheptenes represented by the following formula: ##STR1## where R' is hydrogen, alkyl having 1 to 12 carbon atoms, or ##STR2## where n is an integer from 2 to 4, inclusive, and R.sup.4 and R.sup.5 are independently lower alkyl having 1 to 6 carbon atoms or together R.sup.4 and R.sup.5 and the nitrogen atom to which they are attached form a heterocyclic ring having 5 or 6 total ring atoms; one of R.sup.2 and R.sup.3 is hydrogen and the other is hydrogen, methyl, or ethyl, or together R.sup.2 and R.sup.3 are methylene; and the pharmaceutically acceptable salts thereof. The compounds have anti-inflammatory, analgesic, and antipyretic activities and, accordingly, are useful in the treatment of inflammation, pain and/or pyrexia.
以下是由下式表示的2-取代-5-氧代-5H-二苯并[a,d]环庚烯:##STR1## 其中R'为氢,具有1至12个碳原子的烷基,或##STR2## 其中n为2至4的整数,R.sup.4和R.sup.5独立地为具有1至6个碳原子的低级烷基,或者一起R.sup.4和R.sup.5和它们附着的氮原子形成具有5或6个总环原子的杂环环;R.sup.2和R.sup.3中的一个为氢,另一个为氢,甲基或乙基,或者R.sup.2和R.sup.3一起为亚甲基;以及其制备的药学上可接受的盐。这些化合物具有抗炎,镇痛和解热活性,因此在治疗炎症,疼痛和/或发热方面有用。
