Novel halogenated 1,4-dihydropyridines: synthesis, bioassay, microsomal oxidation and structure-activity relationships

Nine new 1,4-dihydropyridines (DHPs) were synthesized and evaluated for their relaxant ability (rat aorta) and their antihypertensive activity in spontaneously hypertensive rats; their microsomal oxidation rate (MOR) was determined.In terms of relaxant activity, the 4-(3,5-difluorophenyl) analogues were more potent than those with 4-(4-fluorophenyl) but weaker than those with 4-(3-nitrophenyl) substituents, while in terms of antihypertensive activity the 4-(3,5-difluorophenyl) derivatives were more potent than their 4-(3-nitrophenyl) analogues.Their MOR could beexplained the basis of the electron-withdrawing effect of the substituents, and in some cases they permitted a rationalization of discrepancies noted between DHP antihypertensive and relaxant activities.A parabolic relationship was found between the size of the carboxylic ester substituents and their contributions calculated from a Free-Wilson/Fujita-Ban analysis of relaxant activity data. 1,4-dihydropyridine / aorta relaxant activity / antihypertensive activity / microsomal oxidation rate / structure-activity relationship.
