Abstract The acid-catalyzed tautomerization of 3-O-substituted kryptogenin 2 was studied, and the effects of acids such as silica gel, TMSOTf, acetic acid, and CDCl3, are discussed. Additionally, a Zn/KI/HOAc reduction based on this tautomerization was adopted, which afforded 2 directly, and provided a facile procedure for the synthesis ...

ABSTRACT: Protodioscin is a naturally occurring steroidal saponin found in several medicinal plants, particularly Tribulus terrestris, Dioscorea species, and fenugreek (Trigonella foenum-graecum). Growing interest in protodioscin has led to increasing research on its chemical properties, biological activities, analytical characterization, and ...

To study the effects of methyl protodioscin on the [Ca2+]i and the ATPase activity in cardiomyocytes, as well as their mechanisms.The cardiomyocytes were randomly divided into three groups, the control group treated with no serumal DMEM, the MPD group treated with MPD and the dilthiazem group treated with dilthiazem. Fluorospectrophotometer was used to
