The invention relates to new 6-or 7-methylenandrosta-1,4-diene-3,17-diones of the following formula
wherein R is hydrogen or fluorine; R1 is hydrogen or C1-C6 alkyl; R2 is hydrogen or halogen; one of R3 and R4 is = CH2 and the other is hydrogen or C1-C4 alkyl, and when R3 is = CH2, at least one of R and R4 is other than hydrogen; and the symbol -(x)- represents a double bond and the symbol -(y)- represents a single bond when R3 is = CH2 or the symbol -(x)- represents a single bond and the symbol -(y)- represents a double bond when R4 is = CH2, which are useful in therapy, in particular as anti-cancer agents.
本发明涉及下式的新的 6-或 7-亚甲基
