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.
