Synthesis and Calcium Antagonistic Activity of 8-[N-[2-(3,4-Dimethoxyphenyl)ethyl]-β-alanyl]-5,6,7,8-tetrahydrothieno[3,2-b][1,4]thiazepine Fumarate
agent with vasodilating activity. Since it carries a homoveratryl group in the side chain, an obvious relation exists to the verapamil‐type calciumantagonists. Replacement of the fused aromatic moiety in KT‐362 with thiophene provided 8‐[N‐[2‐(3,4‐dimethoxyphenyl)ethyl]‐β‐analyl]‐5,6,7,8‐tetrahydrothieno[3,2‐b][1,4] thiazepine (1). Compound 1 shows a negative chronotropic activity in spontaneously beating
