Document Type and Number:
WIPO Patent Application WO/1995/013272
Kind Code:
A1
Abstract:
A chroman derivative represented by general formula (I), a pharmaceutically acceptable salt thereof, and a medicinal use thereof, wherein R1 is cyano, nitro, trihalomethyl, trihalomethoxy or halogen; R2 is lower alkoxyalkyl, aryloxyalkyl or dialkoxyalkyl; R3 is lower alkoxyalkyl or aryloxyalkyl; R4 is hydroxy, formyloxy or lower alkanoyloxy; X is N-H which may be substituted by lower alkyl, oxygen, sulfur or a single bond; Y is a residue of an aromatic or heterocyclic ring which may be substituted. The compound and pharmaceutically acceptable salt thereof have a prominent selective coronary vasodilator activity while having a minimized hypotensive effect. Therefore, they can selectively increase the coronary blood flow volume without the fear of causing sudden hypotension causative of tachycardia which adversely affects the heart, and hence are useful as a coronary vasodilator, in particular, as a preventive or remedy for cardiovascular disturbance such as angina pectoris or cardiac failure.
