  The effect of the 3-carboxylic-ester variation in 2, 2-dimethyltrimethylene 3-alkoxycarbonyl-4-aryl-1, 4-dihydro-2, 6-dimethyl-5-pyridinephosphonates (1) was investigated with relation to the calcium-antagonistic and antihypertensive activities : the analogs contaning the alkyl groups of not more than 12 carbons and an amino functionality in the carboxylic-ester moiety were synthesized to be examined for biological activities. Among them, 2-[benzyl(phenyl)amino]-ethyl 5(5, 5-dimethyl-2-oxo-1, 3, 2-dioxaphosphorinan-2-yl)-1, 4-dihydro-2, 6-dimethyl-4-(3-nitrophenyl)-3-phridine-carboxylate hydrochloride ethanol (NZ-105) showed particularly beneficial activities and was selected for further pharmacological studies and clinical development. Some aspects of the structure-activity relationships and solid-state structure of NZ-105 by X-ray crystallographic analysis were described.

  A series of phosphonate derivatives, designed as analogues of 1, 4-dihydropyridine-3, 5- dicarboxylates in which a phosphonate group was introduced instead of the carboxylate group at the 5-position, was synthesized, and their antihypertensive activities were examined. Among the compounds examined, 5-diallyloxyphosphinyl-1, 4-dihydropyridine-3-carboxylates were most effective in lowering the blood pressure in normotensive rats and spontaneously hypertensive rats (SHR). The phosphonate derivatives are considered to be close analogues of the carboxylate derivatives. The structure-activity relationships are discussed.

  A series of 1, 4-dihydropyridine-5-cyclic phosphonate derivatives, designed as analogues of 1, 4- dihydropyridine-3, 5-dicarboxylate calcium antagonists, was synthesized and examined for antihypertensive activity. Several compounds were proved to have activities superior or comparable to that of nifedipine in lowering blood pressure in normotensive and spontaneously hypertensive rats (SHR).
