The invention provides compounds of formula (I),
1
wherein R
1
represents C
1-4
alkoxy optionally substituted by one or more fluorine atoms; R
2
represents H or C
1-6
alkoxy optionally substituted by one or more fluorine atoms; R
3
represents one or more groups independently selected from H, halogen, C
1-4
alkoxy and CF
3
; in addition, R
2
and one R
3
group may together represent —OCH
2
—, the methylene group being attached to the ortho-position of the pendant phenyl ring; R
4
represents a 4-, 5- or 6-membered heterocyclic ring containing 1 or 2 heteroatoms selected from N, O and S, the ring being optionally fused to a benzene ring or a 5- or 6-membered heterocyclic ring containing 1 or 2 heteroatoms selected from N, O and S, the ring system as a whole being optionally substituted; X represents CH or N; and L is absent or represents a cyclic group or an open chain group; and the pharmaceutically acceptable salts thereof. The compounds of formula (I) are useful in the treatment of inter alia benign prostatic hyperplasia.
本发明提供了式(I)的化合物,其中R1代表C1-4烷氧基,该烷氧基可以选择性地被一个或多个氟原子取代;R2代表氢或C1-6烷氧基,该烷氧基可以选择性地被一个或多个氟原子取代;R3代表一个或多个基团,这些基团独立选择自氢、卤素、C1-4烷氧基和CF3;此外,R2和一个R3基团可以共同代表-OCH2-,该亚甲基基团连接到悬垂苯环的邻位;R4代表一个4、5或6元杂环环,其中包含1或2个从N、O和S中选择的杂原子,该环可以选择性地与苯环或一个5或6元杂环环融合,该环系作为一个整体可以选择性地被取代;X代表CH或N;L不存在或代表一个环状基团或开链基团;以及其药学上可接受的盐。式(I)的化合物在治疗良性前列腺增生等方面有用。
