There are described compounds of formula I, ##STR1## in which Ra is hydrogen, alkyl, alkenyl or phenyl, R.sub.3, R.sub.5, R.sub.7 and R.sub.8, which may be the same or different, are each hydrogen, alkyl, alkoxy, halogen, hydroxy, alkenyl or phenyl, Rx is hydrogen or alkyl, Ry and Rz are both hydrogen, or together represent a carbonyl oxygen atom, Rb and Rc are both hydrogen or together represent a carbon-carbon bond, Provided that when Rx is hydrogen, Ry and Rz together represent a carbonyl oxygen atom and R.sub.5, R.sub.7 and R.sub.8 are all hydrogen then Ra is other than methyl or phenyl, And pharmaceutically acceptable derivatives thereof. There are also described methods for making the compounds and pharmaceutical, e.g. anti-inflammatory, compositions containing the compounds.
描述了化合物的结构式I,其中Ra是氢、烷基、烯基或苯基,R.sub.3、R.sub.5、R.sub.7和R.sub.8可以相同也可以不同,分别是氢、烷基、烷氧基、卤素、羟基、烯基或苯基,Rx是氢或烷基,Ry和Rz都是氢,或者一起代表一个羰基氧原子,Rb和Rc都是氢,或者一起代表一个碳-碳键,但是当Rx是氢时,Ry和Rz一起代表一个羰基氧原子,而且R.sub.5、R.sub.7和R.sub.8都是氢时,Ra不是甲基或苯基,以及其药学上可接受的衍生物。还描述了制备这些化合物的方法以及含有这些化合物的药物,例如抗炎药物组合物。
