Abstract

The invention comprises 4b , 5a -substituted steroid compounds of the general formula: <FORM:0849098/IV(b)/1> wherein R represents (H)OH, (H)OCOCH3, O, (H)COCH3, (H)COCH2OH or (H)COCH2 OCOCH3, R1 represents (H)H, (H)OH or O, and R111 represents a hydroxyl or acyloxy group or a bromine, fluorine or chlorine atom, and the preparation thereof by reacting a 4a ,5-epoxy-3-keto-steroid of the general formula: <FORM:0849098/IV(b)/2> wherein R and R1 have the above significance, with a non-halogen containing mineral acid such as sulphuric acid in the presence of acetone to obtain compounds in which R1 is OH or with a hydrohalic acid in the presence of acetic acid to obtain compounds wherein R111 represents the halogen atom, compounds in which R111 represents an acyloxy group being obtained by acylating the compounds in which R111 represents a hydroxy group. In the examples allopregnane -4b , 5a -diol-3, 20-dione, androstane-4b , 5a , 17b -triol-3-one-17-acetate, 4b -bromo (and chloro) -allopregnan-5a -ol-3, 20-dione 4b -bromo (and chloro)-allopregnan-5a -ol-3, 11, 20-trione, and 4b -chloro-androstane-5a , 17b -diol-3-one-17-acetate are prepared. Specifications 838,771,838,772, and 838,773 are referred to.ALSO:A therapeutic composition comprises at least one compound of the general formula:- <FORM:0849098/VI/1> wherein R represents (H)OH, (H)(OCOCH3, O, (H)COCH3, (H)COCH2OH or (H)COCH2 OCOCH3, R1 represents (H)H, (H)OH or O, and R111 represents a hydroxy or acyloxy group or a bromine, fluorine or chlorine atom, and a therapeutically acceptable carrier compatible therewith.
