- 4-fluoroalkyl-2h-benzopyrans anti-estogenic activity
-
This invention describes the new 4-fluoroalkyl-2H-benzopyrans of general formula I, in which Z is a straight-chain or branched-chain alkyl group with up to 5 carbon atoms that is fluorinated in at least one place, preferably a trifluoromethyl group, and R1, R2, X, Y and n have the meanings that are indicated in the description. The new compounds have at their disposal strong antiestrogenic action. In addition, they can have at their disposal estrogenic action that occurs in a tissue-selective manner. They can be used for the production of pharmaceutical agents, especially for the treatment of estrogen-dependent diseases and tumors and pharmaceutical agents for hormone replacement therapy (HRT) as well as for the prevention and treatment of osteoporosis.
