Abstract
New 17α-fluorosteroid compounds of formula (I) are disclosed:wherein R1 denotes H or methyl; R2 and R3 each denote H, Cl or methyl; and either a double bond or a single bond is present between C-6 and C-7 and also C-9 and C-10 of the steroid ring system respectively. These compounds have an activity profile with hybrid character so that they act as inhibitors for 5α-reductase and as high potency gestagens. Pharmaceutical compositions containing them are disclosed. They are suitable for treatment of conditions, which are caused by high levels of androgen in organs and tissues. These new compounds can be used in combination with other hormonal substances, such as estrogens, testosterone and other androgens, as contraceptives and for other applications.
