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.
以下是公式I或公式II表示的化合物及其盐:
(1)公式I:##STR1## 其中取代基R.sub.1-R.sub.7可以是独立的氢、羟基、C.sub.1-6烷基(氧)基、乙酰酯或C.sub.1-12烷基丙醇胺;至少三个但不超过四个取代基是烷基(氧)基、羟基或乙酰酯;最多只有一个取代基可以是C.sub.1-12烷基丙醇胺;R.sub.1,R.sub.3,R.sub.7不能同时都是羟基;R.sub.6是羟基或含氧葡萄糖。
(2)公式II:##STR2## 其中取代基R.sub.1-R.sub.9可以是独立的氢、羟基和C.sub.1-6烷基(氧)基;最多只有四个取代基可以是甲氧基、羟基或乙酰酯。这些化合物被证明能够抑制血小板聚集、房室传导和心肌细胞中的钙离子流入。
