    摘要: The invention relates to cycloalkyl-substituted 4-pyridyl deri­vatives of formula (I)
    wherein
    R is C₁-C₄ alkyl;
    each of R₁ and R₂ is, independently, hydrogen or C₁-C₄ alkyl;
    n is an integer of 1 to 5; and either
    (a) A is >C=O and B is -O-, -NH- or -CH₂-; or
    (b) A is -CH₂- and B is -O-, -NH-, -CH₂- or >C=O; or
    (c) A is -O- and B is >C=O or -CH₂-; or
    (d) A is -NH- and B is >C=O or -CH₂-,
    and their pharmaceutically acceptable salts.
    The compounds of the invention show aromatase inhibiting activity and can be useful, e.g., in treating hormone-dependent tumors and prostatic hyperplasia.
