Abstract:
Six new polyhydroxylated spirostanol saponins (1–6) were isolated from the methanolic extract of the rhizomes of Convallaria majalis. On the basis of extensive spectroscopic analysis, including 2D NMR data, and a few chemical transformations, the structures of 1–6 were determined to be 1β,2β,3β-trihydroxy-5β-spirost-25(27)-en-5-yl β-D-galactopyranoside (1), (25 S)-1β,2β,3β-trihydroxy-5β-spirostan-5-yl β-D-galactopyranoside (2), 1β,2β,3β,4β-tetrahydroxy-5β-spirost-25(27)-en-5-yl β-D-galactopyranoside (3), (25 S)-1β,2β,3β,4β-tetrahydroxy-5β-spirostan-5-yl β-D-galactopyranoside (4), 1β,2β,3β,4β-t

The structure was determined by extensive NMR spectroscopy studies and chemical conversions. Its effects on the Na+-ATPase and (Na++K+)-ATPase activities of the proximal tubule from pig kidney were evaluated. It was observed that this steroidal saponin exerts a biphasic effect on the Na+-ATPase activity. It is c

Abstract:
Our preliminary screening identified an extract from the rhizome of Dioscorea tokoro, which strongly suppressed the proliferation of HepG2 hepatocellular carcinoma cells and inhibited autophagy. This study aimed to isolate active compounds from the rhizome of D. tokoro that exert antiproliferative effects and inhibit autophagy. The bioassay-guided fractionation of the active fraction led to the isolation of two spirostan-type steroidal saponins, dioscin (1) and yamogenin 3-O-α-l-rhamnopyranosyl (1→4)-O-α-l-rhamnopyranosyl(1→2)-β-d-glucopyranoside (2), and the frostane-type steroidal saponin pr

The fruits of Solanum torvum Swartz, a wild relative of eggplant, are consumed as a wild vegetable in tropical regions of Africa, Asia, and South America. In traditional Chinese medicine, it is believed to have anti-inflammatory and sedative effects. In the Philippines, water decoction is used to treat hyperactivity disorder. Twenty-two steroidal saponins were isolated and purified from the fruits grown in Yunnan, China, including six new compounds: torvosides U–Z (1–6). During drying and cooking, the saponins may undergo transformation, resulting in small amounts of sapogenins. These transfor

Abstract:
Methods for the preparation of novel antifungal saponins have been investigated in order to further explore their medicinal utility and provide the opportunity to synthesize their derivatives. Through this work, several partially protected stereoisomers of Cholestane, Androstane and Spirostane have been prepared which could be used for the synthesis of various saponin derivatives in order to discover novel saponin based antifungal agent. Various mono and disaccharide derivatives of these steroids have been synthesized and evaluated for their antifungal activity against four pathogenic fungal s

Invasive fungal infections are prevalent and often deadly in immunocompromised patients. There continues to be a pressing need for the development of novel antifungal compounds since there are currently only 13 compounds licensed for the treatment of invasive fungal infections and antibiotic-resistant strains have been emerging. CAY-1 is an antifungal steroidal saponin which was isolated from the fruit of the cayenne pepper plant in 0.1% yield. In Vitro studies of CAY-1 have shown it to be an effective antifungal agent against sixteen pathogenic fungal strains and it showed no cytotoxicity tow
