<p>1,2:5,6-Dianhydrogalactitol is a drug that has been shown to reduce the growth of tumors in mice. It is an antitumor agent that inhibits the activity of enzymes such as protein kinase A and phosphorylase kinase. This drug also inhibits the activity of the mitochondrial membrane potential, which is necessary for normal cellular function. The structure of 1,2:5,6-dianhydrogalactitol was first determined by analytical methods on mouse tumor tissue and then verified by a preparative high performance liquid chromatography (HPLC) experiment. It has been shown to be effective against pediatric tumors and is currently being evaluated for use in other cancer models.</p>

<p>The core trisaccharide of the ganglioside GD2,protected with a propargyl glycoside group, is the most prominent alkynyl glycoside used in oligosaccharide synthesis (Das, 2016). The structure (sodium salt) comprises (GalNAcβ1,4Galβ1,4Glc) of its two sialic acids linked α2,3/α2,8 to the central galactose residue (Ledeen, 2009). GD2 ganglioside is expressed at a low concentration in the central nervous system, nerves, skin melanocytes and stem cells in healthy adults. On the other hand, GD2 ganglioside is overexpressed in a number of tumors including neuroblastoma, melanoma, small cell lung carcinoma and brain tumors. Recently, GD2 ganglioside has been found in low concentrations on breast cancer stem cells (CSC) that possess: self-renewal properties (division without disrupting the undifferentiated state) and tumor-initiating capabilities. It has been suggested that GD2 ganglioside may be developed as an effective target antigen for CSC immunotherapy (Fleurence, 2017).</p>

<p>Frucoste-proline is a l-amino acid that is found in the leaves of tobacco plants. Frucoste-proline is synthesized by dehydration of L-proline, which is catalyzed by the enzyme tabacum l. Frucoste-proline can also be found in maltol and diazepine. The major function of frucoste-proline is to act as a cofactor for enzymes involved in the synthesis of aromatic compounds such as aldehydes and sulfides. This amino acid has been identified as an analytical marker for tobacco leaf, due to its low energy and high specificity.</p>

<p>D-Sorbitol hexahydrate is a sugar that is used in the food industry as a substitute for sucrose. It is also an important component of many pharmaceuticals and other products. Sorbitol hexahydrate can be synthesized from glucose, which is oxidized to sorbitol, and then hydrolyzed by sulfuric acid to produce D-sorbitol hexahydrate. The product is often used as a sweetener for diabetic patients because it does not cause blood glucose levels to rise rapidly. Sorbitol hexahydrate also has anti-inflammatory properties and can be used in the treatment of gastric ulcers.</p>

<p>4-Epi-daunosamine is a glycopeptide antibiotic that is used to treat infections caused by Gram-positive bacteria. It binds to the cell wall of these bacteria and inhibits the synthesis of new cell walls. This causes the cells to burst and die, which leads to bacterial death. 4-Epi-daunosamine has been shown to be effective against animal pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, and Clostridium perfringens. 4-Epi-daunosamine also has a low level of toxicity in humans, but can cause adverse effects such as nausea and vomiting if taken in large doses.</p>
