This invention relates to an ocular hypotensive agent which comprises a compound represented by the formula:
wherein R¹ represents hydrogen or an optionally substituted hydrocarbon residue that may be bound via a hetero atom; R² represents hydrogen or a hydrocarbon residue that may have a substituent; R³ represents a group capable of forming an anion or a group capable of changing thereto; X is a covalent bond between the 2 benzene rings or a spacer having a chain length of 1 to 2 atoms as the linear moiety between the adjoining phenylene group and phenyl group; n represents 1 or 2; ring A is a benzene ring having 1 or 2 optional substituents in addition to the group represented by COOR², or a pharmaceutically acceptable salt thereof.
本发明涉及一种降眼压剂,它由一种由式表示的化合物组成:
其中R¹代表氢或可通过杂原子结合的任选取代的烃残基;R²代表氢或可具有取代基的烃残基;R³代表能够形成阴离子的基团或能够转变为阴离子的基团;X是2个苯环之间的共价键或链长为1至2个原子的间隔物,作为相邻亚苯基和苯基之间的线性分子;n代表1或2;环A是除COOR²代表的基团外具有1或2个任选取代基的苯环,或其药学上可接受的盐。
