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.
