5-Dihydro-4-methyl-2-phenyl-1,5-benzothiazepine-3-carboxylic acidesters, based on the structures of dihydropyridines and diltiazem, were synthesized from o-aminothiophenol and 2-(phenylmethylene)- 3-oxobutanoic acidesters. Biological evaluation in the potassium-depolarized rabbit aorta suggests that these compounds are calcium channel blockers. The in vitro activity was further confirmed by electrophysiological
