History

Japanese scientists firstly reported and analyzed the structure of dioscin isolated from the saponins of Japanese Dioscoreaceae. V . However, the biological activities of dioscin have not attracted the interests of scientists until the late 1990s and the beginning of this century. It is now believed that dioscin may have therapeutic effects on reducing blood lipids and protecting the liver, as well as antivirus, antiinflammatory, and antitumor effects. After the implementation of standardization of traditional Chinese medicine, dioscin as the quality control specification of Dioscorea nipponica Makino and other traditional Chinese medicine has attracted more attentions and researches. In China, dioscin tablets have been used to treat hyperlipidemia in the clinical practice. However, no corresponding drugs are available on the market in other countries. In addition, dioscin is also an important predecessor for synthesizing steroid hormones . Dioscorea nipponica Makino, which is used to extract dioscin, primarily comes from wild plants, whose resources are limited.

Uses

Different sources of media describe the Uses of 19057-60-4 differently. You can refer to the following data:
1. Dioscin, a natural steroid saponin that has been shown to promote anticancer activity against several forms of cancers. Dioscin induces cancer cell apoptosis through elevated oxidative stress mediated by downregulation of peroxiredoxins.
2. Dioscin, a natural steroid saponin that has been shown to promote anticancer activity against several forms of cancers. Dioscin induces cancer cell apoptosis through elevated oxidative stress mediated by downregulation of peroxiredoxins.

Indications

This drug was recorded in the national standards for chemical drugs, volume 5. Dioscin tablets, containing total dioscin, are used to treat coronary heart disease, coronary insufficiency, as well as control hyperlipidemia.

Pharmacology

Studies showed that compound preparations containing dioscin can increase coronary blood flow, reduce myocardial oxygen consumption, and protect myocardial ischemia and ischemia-reperfusion injury, which is beneficial for alleviating myocardial ischemia and angina. In addition, dioscin can regulate the lipid metabolism and improve hemodynamics. Dioscin can also prevent atherosclerosis by reducing serum total cholesterol, triglyceride, low-density lipoprotein, and oxidized lowdensity lipoprotein, reducing the whole blood viscosity and plasma viscosity at high and low shear rates, and relieving arterial wall lipid infiltration and plaque formation. Furthermore, dioscin can reduce liver fat deposition, which may be related to promoting cholesterol secretion metabolism.It has also been reported that dioscin can induce the apoptosis of a variety of tumor cells, including gastric cancer cells, breast cancer cells, lung cancer cells, oral squamous cell carcinoma, and cervical cancer cells. The mechanisms are related to reducing the oxidative stress and inhibiting some cellular survival signaling pathways Dioscin can induce antioxidant enzymes, lower blood lipids, improve insulin resistance, inhibit the inflammatory response, reduce the damage of alcoholic hepatitis, and decrease the hepatic injury induced by acetaminophen .

Synthesis of novel diosgenyl saponin analogs and evaluation effects of rhamnose moeity on their cytotoxic activity

Diosgenyl saponins, as a type of natural products derived from plants, are the main active component of traditional chinese medicine. Inspiringly, a large number of natural diosgensyl saponins have been shown to exert excellent toxicity to hepatocellular cancer (HCC) cells. In order to better understand the relationship between the structures and their biological effects, a group of diosgenyl saponins (1–4 as natural products and 5 and 6 as their analogs) were efficiently synthesized. The cytotoxic activity of these compounds was evaluated on human hepatocellular carcinoma (HepG2) cells. Structure–activity relationship studies showed that the pentasaccharide or hexasaccharide saponin analogs were relatively less active than their corresponding disaccharide analogue or dioscin. The extension of 4-branched rhamnose moiety on these saponin does not exhibit significant effect on their cytotoxic activity, which disclosed that a certain number and the linkage mode of rhamnose moieties could influence the cytotoxicity of steroid saponins on HepG2 cells.

N-Pentenyl-Type Glycosides for Catalytic Glycosylation and Their Application in Single-Catalyst One-Pot Oligosaccharide Assemblies

We have developed a new type of n-pentenyl-type glycosides that can be activated by catalytic amounts of promoter, Hg(NTf2)2 or PPh3AuCl/AgNTf2, at room temperature. The mild activation conditions and outstanding stability of common protection/deprotection manipulations enable the enynyl donors to have broad applications in constructing various glycosidic bonds. Furthermore, under the Hg(NTf2)2-catalyzed conditions, the sequential activation of different types of donors was achieved, based on which a gentiotetrasaccharide was synthesized via the newly developed single-catalyst one-pot strategy.

Efficient synthesis of α- and β-chacotriosyl glycosides using appropriate donors, and their cytotoxic activity

Natural steroidal glycosides containing α-l-rhamnopyranosyl-(1→4)-[α-l-rhamnopyranosyl-(1→2)]-β-d-glucopyranose (chacotriose) at the oligosaccharide moiety exhibit anti-cancer and anti-herpes activities. To investigate the structure-activity relationships of the aglycone parts of chacotriosides, we developed a synthesis method for chacotriosyl glycosides having various aglycones. In the process, it was revealed that α-chacotriosyl glycosides could be obtained mainly by using a trichloroacetimidate donor, while β-chacotriosyl glycosides were afforded by using phosphite and phosphate donors. In cytotoxicity tests using the A549 and HepG2 cell lines, naturally occurring β-chacotriosyl diosgenin and cholestanol exhibited higher activities than the corresponding α-chacotriosyl glycosides.
