摘要:
The invention concerns the provision of novel 1,4-dihydropyridine-sugar derivatives and processes for their preparation. The invention also concerns pharmaceutical compositions containing the compounds of the invention and methods for their use. The products of the invention, such as 2-[1,4-dihydro-5-(2-propyl)-oxycarbonyl-2,6-dimethyl-4-m-nitrophenyl-3-pyridylcarbonyloxy]-ethyl .beta.-D-glucopyranoside, are effective for the treatment of circulatory disorders and can be used as antihypertensive agents, vasodilators or coronary therapeutic agents.
摘要:
The invention relates to new dihydropyridines which are substituted by an amino group in at least one of the 2- and 6-positions, by a sulphur-containing substituent in the 3-position, by a cyclic substituent in the 4-position and by a carbonyl substituent in the 5-position. The new dihydropyridines are particularly useful as agents which influence the circulatory system. Also included in the invention are procedures for preparation of the new dehydropyridines, compositions containing them and methods for their use.
