The invention relates to novel steroids having the formula:
wherein
X = CH2-S-R3 or S-S-R4;
R1 = 0 or H (βR5);
R2 = 0 or H (βR6);
R3 = H, acyl (1-18C) or alkyl (1-4C);
R4 = H, acyl (1-18C) or hydrocarbyl (1-18C), the acyl or hydrocarbyl group being optionally substituted;
R5 = OH, O acyl (1-18C) or an ether group;
R6 = OH, O acyl (1-18C) or an ether group;
and the dotted lines represent a carbon-carbon bond in 4,5-or 5,6 position; to processes for their preparation and to pharmaceutical compositions containing these steroids as active constituents.
The novel compounds possess particularly aromatase- inhibiting properties.
