Abstract
A compound, and salts thereof, represented by either formula I or formula II below: (1) Formula I: ##STR1## wherein substituents R.sub.1 -R.sub.7 can be, independently, hydrogen, hydroxy group, C.sub.1-6 alkyl(oxy) group, acetyl ester, or C.sub.1-12 alkyl propanolamine; at least three but no more than four of the substituents are alkyl(oxy) group, hydroxyl group or acetyl ester; no more than one of the substituents can be C.sub.1-12 alkyl propanolamines; R.sub.1, R.sub.3, R.sub.7 cnnnot all be hydroxy groups at the same time; and R.sub.6 is either an hydroxy group or an oxygen-containing glucose. (2) Formula II: ##STR2## wherein substituents R.sub.1 -R.sub.9 can be, indenpendently, hydrogen, hydroxy group and C.sub.1-6 alkyl(oxy) group; and no more then four of the substituents can be methoxy group, hydroxy group, or acetyl ester. These compounds were tested to be capable of inhibiting platelet aggregation, atrioventricular conduction, and calcium influx in myocardiac cells.
