Arrowsmith, John E. published the artcileLong-acting dihydropyridine calcium antagonists. 1. 2-Alkoxymethyl derivatives incorporating basic substituents, HPLC of Formula: 93118-03-7, the main research area is aminoalkoxymethyldihydropyridinedicarboxylate preparation calcium antagonist; pyridinedicarboxylate aminoalkoxymethyldihydro; vasodilator aminoalkoxymethyldihydropyridinedicarboxylate preparation.
Aminoalkoxymethyldihydropyridines I [R = Ph, substituted Ph, 1-naphthyl, 2-thienyl, 4-pyridyl; R1 = (un)substituted NH2; n = 2, 3] were prepared from RCHO, R1(CH2)nOCH2COCH2CO2Et, and H2NCMe:CHCO2Me or via I (R = N3, phthalimido). Their potencies as Ca antagonists were determined I (R = 2-ClC6H4, R1 = NH2, n = 2) (amlodipine) was comparable in potency to nifedipine and had an elimination half-life of 30 h in dogs. Oral bioavailability approached 100%, and hemodynamic responses were gradual in onset and long-lasting in effect. The two enantiomers were prepared; the bulk of the activity resided with the (-)-isomer. X-ray crystallog. studies, carried out on I (R = 2-ClC6H4, R = morpholinosulfonyl, n = 2) suggest the existence of a weak H bond between the side-chain O and the H on the ring N.
