A 6.alpha.-methylprednisolone derivative of the general formula: ##STR1## wherein R.sup.1 is a hydrogen atom or stands for the grouping ##STR2## where R.sup.3 is a straight or once-branched chain C.sub.1-4 alkyl group, a phenyl group or a lower alkoxy- or alkylthio-methyl group, and R.sup.2 is a straight or once-branched chain C.sub.1-4 alkyl group, a phenyl group or a lower alkoxy- or alkylthio-methyl group, with the proviso that when R.sup.2 is ethyl group, R.sup.1 should not be a hydrogen atom or R.sup.3 should not be ethyl group. This compound exhibits a strong local antiinflammatory effect and is, therefore, useful as a harmless external antiinflammatory drug for various dermal disorders and also as an antiallergic drug for treating asthma and the like allergic diseases.
一种6-α-
甲基泼尼松衍
生物,其一般式为:##STR1## 其中R.sup.1是氢原子或代表基团的标记##STR2##其中R.sup.3是直链或一次分支的C.sub.1-4烷基,苯基或较低的烷氧基或烷
硫基甲基基团,R.sup.2是直链或一次分支的C.sub.1-4烷基,苯基或较低的烷氧基或烷
硫基甲基基团,但当R.sup.2是乙基基团时,R.sup.1不应是氢原子或R.sup.3不应是乙基基团。该化合物表现出强烈的局部抗炎效果,因此可用作各种皮肤疾病的无害外用抗炎药以及治疗哮喘和其他过敏疾病的抗过敏药。
