Abstract

Abstract Calcium channel blocking activity is exhibited by compounds having the formula ##STR1## or a pharmaceutically acceptable salt thereof, wherein the stereochemistry at the chiral centers in the 3 and 4-positions of the benzothiazepine nucleus is cis, and wherein R 1 is alkyl, aryl, arylalkyl, alkenyl or alkynyl; R 2 and R 5 are each independently hydrogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, halogen or trifluoromethyl; and R 3 and R 4 are each independently alkyl or cycloalkyl or R 3 and R 4 together with the nitrogen atom to which they are attached are pyrrolidinyl, piperidinyl or morpholinyl.
