    Asymmetric 4-aryl-1, 4-dihydro-2, 6-dimethyl-3, 5-pyridinedicarboxylates with a 2-ethylenedioxypropyl, 2-oxopropyl, or cyclopropylmethyl group as the ester moiety and related derivatives were synthesized and tested for vasodilating activity in anesthetized open-chest dogs and for antihypertensive activity in conscious spontaneously hypertensive rats. Cyclopropylmethyl methyl 1, 4-dihydro-2, 6-dimethyl-4-(3-nitrophenyl)-3, 5-pyridinedicarboxylate (5f, MPC-2101) and methyl 2-oxopropyl 1, 4-dihydro-2, 6-dimethyl-4-(2-nitrophenyl)-3, 5-pyridinedicarboxylate (8i, MPC-1304) exhibited potent cerebral vasodilating and antihypertensive activities, respectively. The maximum increase of vertebral blood flow after intravenous administration at 3.0 μg/kg was 221.4% for 5f, compared with 187.0 and 166.3% for nifedipine and nicardipine hydrochloride, respectively. The maximum falls of systolic blood pressure after oral administration of 8i at 0.3 and 1.0 mg/kg were 42.2 and 54.0 mmHg, while those of nifedipine, nicardipine, and hydralazine hydrochloride at 3.0 mg/kg were 23.3, 16.8, and 24.5 mmHg, respectively. The durations of significant vasodilating and antihypertensive effects for 5f and 8i were longer than those of nifedipine and nicardipine.

    Novel 4-arylpyrimidine derivatives were synthesized by the oxidation of 4-aryl-1, 4-dyhydropyrimidines, and their effects on anti-anoxic (AA) activity in mice and anti-lipid peroxidation (ALP) activity in rat mitochondria were investigated. Among these compounds, ethyl 6-methyl-2-phenyl-4-(4-pyridyl)-5-pyrimidinecarboxylate (4b) has AA activity (10mg/kg, i.p.) and ethyl 6-methyl-4-(3-nitrophenyl)-2-phenyl-5-pyrimidinecarboxylate (4f) has ALP activity (73% inhibition at 10<-5>g/ml). The latter compound (100mg/kg, i.p.) was also effective on arachidonate-induced cerebral edema in rats with comparable potency to that of vitamin E.
