7S-+- 88--2--67--2H8H-32-g-7-- Composition for preventing improving or treating eye diseases comprising 7S-+-cyclopentyl carbamic acid 88-dimethyl-2-oxo-67-dihydro-2H8H-pyrano32-gchromen-7-yl-ester as an active ingredient

摘要

The present invention provides (7S)-(+)-cyclopentyl carbamic acid, 8,8-dimethyl-2-oxo-6,7-dihydro- 2H,8H -pyrano[ 3,2-g ]chromene-7 It relates to a composition for preventing, improving or treating eye diseases caused by intraocular blood vessel leakage, comprising -yl-ester as an active ingredient. (7S)-(+)-cyclopentyl carbamic acid of the present invention, 8,8-dimethyl-2-oxo-6,7-dihydro- 2H,8H -pyrano[ 3,2-g ]chromene-7 Since -yl-ester has an effect of remarkably reducing intraocular blood vessel leakage, it can be usefully used as a composition for preventing, improving, or treating eye diseases caused by intraocular blood vessel leakage.
