<p>Safflor Yellow A is a natural drug that has been shown to have hypoglycemic effects. It is a potent inhibitor of glucose-6-phosphatase and glucose-6-phosphate dehydrogenase, which are enzymes involved in the conversion of glucose to glycogen. Safflor Yellow A also inhibits neuronal death, as it blocks the enzyme activities that lead to neuronal cell death. This drug has also shown antitumor activity, as it induces apoptosis in tumor cells. Safflor Yellow A also has antihyperlipidemic effects and can be used for the treatment of coronary heart disease. Low doses of this drug have been shown to reduce systolic pressure in rats and improve blood coagulation. The mechanism of action for this drug is not yet known but may involve toll-like receptor 4 signaling pathways or polymerase chain reaction (PCR).</p>

<p>Lipid IVA is a tetra-acylated precursor molecule of lipid A which is a component of lipopolysaccharides (LPS) on the outer membrane of gram-negative bacteria. On the innate immune cells of hosts there are toll-like receptor 4 (TLR4) and MD-2 which recognize LPS. This recognition event ultimately leads to the activation of NFκB which in turn results in pro-inflammatory cytokine production. Studies have suggested lipid A in Escherichia coli to be an agonist for both mouse and human TLR4, while lipid IVA can induce species specific TLR4 responses. For example for horse and mouse TLR4 and MD-2, Lipid IVA is an agonist where as it is an antagonist for TLR4 and MD-2 in humans.</p>

<p>Trehalose 6-octanoate is a modified form of trehalose that has been synthesized and fluorinated. It is a monosaccharide, which means it is one of the simplest forms of sugar. Trehalose 6-octanoate is an oligosaccharide, which means it is a sugar molecule made up of several smaller sugar molecules. This sugar can be modified to include methyl groups, making it a polysaccharide. Polysaccharides are complex carbohydrates that can often be found in plants or animals. Trehalose 6-octanoate is used in the modification of proteins and lipids for the production of pharmaceuticals and other products.</p>

<p>Sodium alginate is the sodium salt of a polysaccharide obtained from brown seaweeds. The main use for alginate is in textile printing as a thickener in the printing of cottons with reactive dyes. In the food industry it is used as a thickener and gelling agent. The chemical structure consists of blocks of (1,4) linked-β-D-polymannuronic acid (poly M), (1,4) linked-α-L-polyguluronic acid (poly G) and alternating blocks of the two uronic acids (poly MG).</p>

<p>Monofucosyllacto-N-hexaose II is a tetraol that is used as a reagent in the synthesis of enantioenriched and synthetically tetrasaccharidic products. Monofucosyllacto-N-hexaose II can be obtained by the reaction of Grignard reagents with glucose or by stereoselective reduction of an alpha, beta unsaturated ketone. The presence of the glucose residue in Monofucosyllacto-N-hexaose II makes it an acceptor for esterification reactions. This compound has chiral centers due to its two stereogenic centers at C2 and C3, which are both beta positions on the glucose residue. Monofucosyllacto-N-hexaose II also has a free hydroxyl group at C5 that can be esterified to produce chiral esters.</p>

<p>Agarose is a polysaccharide found in red algae, typically Gelidium and Gracilaria. It is a strictly alternating polysaccharide of α-1,3 linked D-galactose and β-1,4 linked L-3,6 anhydrogalactose with occasional sulfation at position 6 of the anhydrogalactose residue. Agaro-oligosaccharides result from cleavage at galactose residues and neoagaro-oligosaccharides from cleavage at 3,6-anhydro residues. Neoagarooctaose is reported to have potential for novel cosmeceuticals.</p>

<p>Maltotridecaose is a sugar alcohol with an acceptor group that can be introduced into a cavity in a molecule. It is a sweetener that has been shown to have oligosaccharide properties, which are the molecules that comprise dietary carbohydrates. Maltotridecaose can be found as an unlabeled ingredient in foods such as sugar-free chewing gum, chocolate, and ice cream. The debranching of maltotridecaose occurs by way of glucans and licheniformis.</p>

<p>3,6-Di-O-acetyl-4-O-(2,3,4,6-tetra-O-acetyl-b-D-galactopyranosyl)-D-glucal is a nacetyllactosamine that is structurally similar to the natural substrate for lactohexosaminidase. This compound inhibits the enzyme activity of this enzyme and other related enzymes. 3,6-Di-O-acetyl-4,6 D -glucal has been shown to inhibit endothelial cell growth in vitro. It also binds to the receptor on endothelial cells and blocks the signal pathways involved in cell growth. The glucose moiety of 3,6 Di O acetyl 4,6 D glucal inhibits lipases by binding to their active sites.</p>
