摘要

The present invention is directed to novel peruvoside derivatives having the formula IMAGE (I) and the formula IMAGE (II) wherein R1 and R2 are the same or different and are selected from a hydrogen atom, an acyl group, an alkoxymethyl group and a carboalkoxy group wherein the alkyl portion of said groups has 1-4 carbon atoms and R3 is an acyl group having 2-5 carbon atoms. Methods of preparation and suitable compositions are also disclosed. Said compounds and compositions are useful for the treatment of cardiac insufficiencies.
