title: Synthesis of some 1,4-dihydropyridine derivatives and their calcium antagonistic activity.
abstract: Seven new 2,6-dimethyl-3,5-diacetyl-4-aryl-1,4-dihydropyridine derivatives have been prepared. Their structures have been elucidated by UV, IR, 1H-NMR and elementary analysis. The calcium antagonistic activity of these compounds were tested in K(+)-depolarized taenia coli precontracted with 1 mmol/l Ca2+.
