A search for calcium-channel activators in the verapamil series.
A new series of phenylalkylamines related to Verapamil have been synthesized and their Ca2+-modulating activity on rabbit aorta and on guinea-pig heart were evaluated. The compounds display only a moderate Ca2+-antagonistic activity; none of them showed any Ca2+-agonistic effect.
