Abstract

1,4-Dihydropyridine (1,4-DHP) derivatives nifedipine of which the prototype, are the most popular drugs having calcium antagonistic activity. Fused 1,4-dihydropyridines (DHPs) have also exhibit calcium modulatory activities. In this article, weemphasizecalcium channels and fused 1,4-DHP derivatives affecting calcium channels. In addition, the basic considerations of synthesis, metabolism, structure-activity relationships and the latest developments on fused 1,4-DHP derivatives will be reviewed. This review also has extended examples of fused 1,4-DHP derivatives having cited activities synthesized by our group.

Keywords: 1,4-Dihydropyridine, hexahydroquinoline, calcium modulatory activity, synthesis, biotransformation, structure-activity relationships
