Academic Editor: Derek J. McPhee Received: 15 August 2016; Accepted: 30 September 2016; Published: 5 October 2016 Abstract: Saponins are glycosides with triterpenoid or spirostane aglycones that demonstrate various pharmacological effects against mammalian diseases. To promote the research and development of anticancer agents from saponins, this review focuses on the anticancer properties of several typical naturally derived triterpenoid saponins (ginsenosides and saikosaponins) and steroid saponins (dioscin, polyphyllin, and timosaponin) isolated from Chinese medicines. These saponins exhibit in vitro and in vivo anticancer effects, such as anti-proliferation, anti-metastasis, anti-angiogenesis, anti-multidrug resistance, and autophagy regulation actions. In addition, related signaling pathways and target proteins involved in the anticancer effects of saponins are also summarized in this work. -

In Chemistry, Glycosides Are Certain Molecules in Which a Sugar Part Is
GLYCOSIDES Glycosides may be defined as the organic compounds from plants or animal sources, which on enzymatic or acid hydrolysis give one or more sugar moieties along with non- sugar moiety. Glycosides play numerous important roles in living organisms. Many plants store important chemicals in the form of inactive glycosides; if these chemicals are needed, the glycosides are brought in contact with water and an enzyme, and the sugar part is broken off, making the chemical available for use. Many such plant glycosides are used as medications. In animals (including humans), poisons are often bound to sugar molecules in order to remove them from the body. Formally, a glycoside is any molecule in which a sugar group is bonded through its carbon atom to another group via an O-glycosidic bond or an S-glycosidic bond; glycosides involving the latter are also called thioglycosides. The sugar group is then known as the glycone and the non-sugar group as the aglycone or genin part of the glycoside. The glycone can consist of a single sugar group (monosaccharide) or several sugar groups (oligosaccharide). Classification Classification based on linkages Based on the linkage of sugar moiety to aglycone part 1. O-Glycoside:-Here the sugar is combined with alcoholic or phenolic hydroxyl function of aglycone.eg:-digitalis. 2. N-glycosides:-Here nitrogen of amino group is condensed with a sugar ,eg- Nucleoside 3. S-glycoside:-Here sugar is combined with sulphur of aglycone,eg- isothiocyanate glycosides. 4. C-glycosides:-By condensation of a sugar with a cabon atom, eg-Cascaroside, aloin. Glycosides can be classified by the glycone, by the type of glycosidic bond, and by the aglycone. -
