Abstract
The new compound thienodiltiazem was synthesized and investigated regarding structure-activity relations and calcium antagonistic properties. Isometric contraction force was measured in guinea-pig papillary muscles and chronotropic activity was studied in right atria of guinea pigs. Compared to the parent drug diltiazem (CAS 42399-41-7) the thieno derivative had a more potent negative chronotropic effect on spontaneously beating right atria and a more potent inotropic effect on papillary muscles. The negative inotropic action was reversed by increasing the extracellular calcium concentration.
