Provided are new biphenyl derivatives of formula (Ia). These compounds act as aromatase and sulfatase inhibitors. They are particularly useful for treating pathological conditions or diseases in which aromatase and sulfatase are involved. Moreover, provided are processes for the preparation of these compounds and pharmaceutical compositions containing said products and their use for the preparation of a medicament, in particular for the treatment of diseases characterized by aromatase and sulfatase activity such as hormone-dependent cancers.

Reaction of hydrazine with α-[(dimethylamino)methylene]-β-oxoarylpropanenitriles 2 gives a mixture of the 4-aroyl-5-aminopyrazoles 3 and the 5-aryl-4-cyanopyrazoles 4. Similarly reaction of 2 with phenylhydrazine gives rise to the 5-amino-4-aroyl-1-phenylpyrazoles 5 and 5-aryl-4-cyano-1-phenylpyrazoles 6. The regioselectivity of addition has been investigated with respect to the electronic nature and steric requirements of the aromatic substitution. The ratio of products was found to be independent of the electronic nature of the substituent. The outcome of the reaction was however very sensitive to steric factors. Substituents in the para- and meta-positions favoured formation of the pyrazole-nitrile products 4 and 6, whereas sterically demanding ortho-substituents favoured the pyrazole-amino ketones 3 and 5.
