Compounds of the formula ##STR1## wherein R.sup.1 represents a fluoro-, chloro- or bromo-methyl group or a 2'-fluoroethyl group, R.sup.2 represents a group COR.sup.6 where R.sup.6 is a C.sub.1-3 alkyl group or OR.sup.2 and R.sup.3 together form a 16.alpha.,17.alpha.-isopropylidenedioxy group; R.sup.3 represents a hydrogen atom, a methyl group (which may be in either the .alpha.- or .beta.-configuration) or a methylene group; R.sup.4 represents a hydrogen, chlorine or fluorine atom; R.sup.5 represents a hydrogen or fluorine atom and symbol represents a single or double bond have good anti-inflammatory activity, particularly on topical applications. The compounds of formula I are prepared by esterification, halogenation, reduction, deprotection and reaction at a 9,11-double bond to form a 9.alpha.-halo-11.beta.-hydroxy grouping. Pharmaceutical compositions containing the compounds of formula I and methods for the use of the compounds are described and claimed.
分子式为##STR1##的化合物,其中R.sup.1代表氟甲基、氯甲基或溴甲基或2'-氟乙基基团,R.sup.2代表一个COR.sup.6基团,其中R.sup.6是C.sub.1-3烷基或OR.sup.2,而R.sup.3则组成一个16.alpha.,17.alpha.-异丙基二氧基基团;R.sup.3代表氢原子、甲基基团(可以是.alpha.-或.beta.-构型)或亚甲基基团;R.sup.4代表氢、氯或氟原子;R.sup.5代表氢或氟原子,符号代表单键或双键,具有良好的抗炎活性,特别是在局部应用时。公式I的化合物通过酯化、卤代、还原、去保护和在9,11-双键处反应形成9.alpha.-卤代-11.beta.-羟基基团来制备。描述并声明了含有公式I的化合物的制药组合物以及使用这些化合物的方法。
