Synthesis and Antihypertensive Activities of New 1, 4-Dihydropyridine Derivatives Containing Nitrooxyalkylester Moieties at the 3- and 5-Positions

Abstract

We have synthesized new 1, 4-dihydropyridine derivatives having nitrooxyalkylester moieties at the 3- and 5-positions in order to develop potent and long-lasting vasodilators. The antihypertensive activities of these compounds were compared with that of nifedipine. One of them, 2-nitrooxypropyl 3-nitrooxypropyl 2, 6-dimethyl-4-(3-nitrophenyl)-1, 4-dihydro-3, 5-pyridinedicarboxylate (CD-349) was selected for further development. The structure-activity relationship is discussed.
