The invention relates to Δ⁴-androstene derivatives with aromatase-inhibiting activity having the formula:
wherein
R₁ = O, (αR₅,βH) or N-O-R₆;
R₂ = H, (1-12C)hydrocarbon radical, -SH, -S-(1-12C)-hydrocarbon radical or (1-12C)acyl;
R3 = O or (αR₇,βR₈); R₄ = H or (1-12C)hydrocarbon radical;
R₅ = OH, O-(1-12C)hydrocarbon radical or O-(1-12C)acyl;
R₆ = H or (1-12C)hydrocarbon radical;
R₇ = H or (1-12C)hydrocarbon radical; and
R₈ = OH, O-(1-12C)acyl or O-(1-12C)hydrocarbon radical with the proviso that R₁ is not O if R₄ is H.
