摘要

The invention provides a dihydropyridine compound of the followng general formular (I) or a salt thereof:
<CHEM>
wherein R<1> and R<2> are the same or different and selected from C1, to C10 alkyl groups, C1 to C5 alkyl groups interrupted by oxygen atom(s), and C1 to C5 alkyl groups substituted by C3 to C6 alicyclic group(s); R<3> and R<4> are the same or different C1 to C5 alkyl groups; R<3> and R<4> are the same or different and selected from hydrogen and halogen atoms and nitro, C1 to C5 alkyl, C1 to C5 alkoxy, C1 to C5 alkylthio, C1 to C5 alkylsulfonyl and C1 to C5 alkylsulfinyl groups; R<7> and R<8> are the same or different and are selected from hydrogen and halogen atoms and cyano, C1 to C5 alkoxy and C1 to C5 alkanoylamino groups or combine to form, with the adjacent phenyl group, a naphthyl group; A represents a single bond, or a vinylene (-CH=CH-) or ethynylene group (-C=C-); B represents a single bond or -CH2O-; and m and n are the same of different and selected from O and integers of 1 to 5, and methods of making such a compound. The compounds may be used for treatment or prevention of ischemic heart-disease and cardiovascular disorders and may show both Ca<2><+> antagonistic action and adrenergic betareceptor blocking activity.
