2-Substituted-5-oxo-5H-dibenzo[a,d]cycloheptenes represented by the following formula: ##SPC1## Where 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 R' and R.sup.4 are alkoxy, or together R' and R.sup.4 are =O, =NOH, =NNHCONH.sub.2, or alkylenedioxy of the formula --O--CH.sub.2 --(CR.sup.5.sub.2).sub.n --CH.sub.2 --O-- where n.sub.5 is O--2, R.sup.5 is hydrogen or methyl when n is 1, and R.sup.5 is hydrogen when n is 2, or one of R' and R.sup.4 is --OH and the other is (SO.sub.3 Y) where Y is sodium or potassium. The compounds have anti-inflammatory, analgesic and anti-pyretic activities and, accordingly, are useful in the treatment of inflammation, pain and pyrexia.
以下式子表示的2-取代基-5-氧代-5H-二苯并[a,d]环庚烯:##SPC1##
其中R.sup.2和R.sup.3中的一个是氢,另一个是氢,甲基或乙基,或者R.sup.2和R.sup.3在一起是亚甲基;R'和R.sup.4是烷氧基,或者一起是=O,=NOH,=NNHCONH.sub.2,或者是式子--O--CH.sub.2--(CR.sup.5.sub.2).sub.n--CH.sub.2--O--的烷二氧基,其中n.sub.5是O-2,当n为1时,R.sup.5是氢或甲基,当n为2时,R.sup.5是氢,或者R'和R.sup.4中的一个是--OH,另一个是(SO.sub.3Y),其中Y是钠或钾。这些化合物具有抗炎,镇痛和退热活性,因此在治疗炎症,疼痛和发热方面有用。
