1,4-Dihydro-6-methyl-4-(substituted phenyl)pyridine-3,5-dicarboxylic acid esters have an amino group at the 2-position and at least one nitrooxy group in at least one of the ester groups. These compounds have a variety of valuable activities, including antihypertensive and Ca.sup.++ -blocking activities, leading to their use for the treatment of circulatory and coronary disorders. They may be prepared by condensation of appropriate substituted acetic acid esters.

Novel 2-Amino-1,4-dihydropyridine Calcium Antagonists. I. Synthesis and Antihypertensive Effects of 2-Amino-1,4-dihydropyridine Derivatives Having Nitroxyalkoxycarbonyl Groups at 3- and/or 5-Position.
Novel 2-amino-1,4-dihydropyridine derivatives, which contain nitroxy-alkoxycarbonyl groups at the 3- and/or 5-position, were synthesized and their pharmaceutical effect was evaluated in spontaneously hypertensive rats. The structure-activity relationships are discussed in terms of potency, onset-rapidity, and duration of antihypertensive activity. Remarkably prolonged duration of antihypertensive action
