It has been shown to inhibit the growth of Mycobacterium tuberculosis in a dose dependent manner. This compound has also been shown to inhibit the synthesis of DNA and RNA in bacterial cells, which may be due to its ability to inhibit glycosylation and methylation reactions.

This product has a molecular weight of 486.83 g/mol, a melting point of 169 oC, and an octanol/water partition coefficient of 3.00.

Fucose (Fuc, 6-deoxy L-galactose) has a methyl group at C6 in place of a hydroxyl group and this gives the molecule a greater degree of hydrophobicity than galactose (Collins, 2006). L-fucose is found in fucoidan, a polysaccharide that occurs in the brown seaweeds (Phaeophyceae) (Percival, 1967). Fucose is also a key component in many mammalian N- and O-linked glycans, glycolipids, blood group substances and Lewis antigens (Becker, 2003). In human milk, neutral (fucosylated) oligosaccharides (HMO) contain fucose at the terminal position (e.g. 2’ -fucosyllactose and lactodifucopentaose). They represent 35% to 50% of the total HMO content and many in vitro studies suggest that HMOs directly modulate immune responses, acting either locally on cells of the mucosa-associated lymphoid tissues or systemically to inhibit the expression of inflammatory genes, mainly cytokines (Plaza-Diaz, 2018).

Zomepirac-acyl-b-D-glucuronide is a metabolite of the nonsteroidal anti-inflammatory drug zomepirac. It binds to plasma proteins, which may affect its pharmacokinetics. Zomepirac-acyl-b-D-glucuronide is excreted in the urine and may be bound to fatty acids. The drug has been shown to form covalent adducts with lysine residues in humans, which may result in potential interactions with other drugs or increased toxicity. The drug has been studied in clinical pharmacology studies that show no significant adverse effects in humans. This metabolite has also been shown to have fatty acid binding properties, which may affect its pharmacokinetics and metabolism.

Methyl 2-acetamido-3,6-di-O-benzyl-2-deoxy-a-D-glucopyranoside is a synthetic saccharide that is used in the synthesis of glycosides. This compound has been modified with fluorine to increase its stability and activity. Methyl 2-acetamido-3,6-di-O-benzyl-2-deoxyglucopyranoside can be used as a building block for glycosylation reactions due to its high purity and custom synthesis. It has been shown that this compound has click modification activity.

5-Iodouridine has shown to enhance the effect of gamma irradiation in hamster cells. It is used as catalytic agent, petrochemical additive, used in organic synthesis. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

4-O-Acetyl-3,6-di-O-tert-butyldimethylsilyl-D-glucal is a methylated derivative of D-glucal which has been synthesized by the click reaction using acetyl chloride, triethylamine, and dimethyl sulfate. 4OATBDMSDG is a high purity sugar with a CAS number of 132891-79-3. This sugar can be used in the synthesis of polysaccharides or as an intermediate for custom synthesis.

Mannose (Man) is the C2 epimer of glucose with one hydroxyl group axial which by Hudsons rules makes it slightly less stable than glucose (Hudson, 1948). However, mannose is very common in plants and animals, and occurs in many polysaccharides, such as, galactomannans (e.g. Guar, Locust Bean Gum), mananns (e.g. Ivory Nut Mannan), Spruce Galactoglucomannan, Gum Ghatti (Whistler, 1993) and baker’s yeast (Saccharomyces cerevisiae) (Manners, 1973). Mannose is one of the key mammalian monosaccharides (Glucose, Galactose, Mannose, Fucose, N-Acetyl Glucosamine, N-Acetyl galactosamine and Sialic acid) and occurs in N-linked glycans where it is a core oligosaccharide (Gabius, 2009).

Methyl 2-deoxy-3,5-di-O-pivaloyl-alpha-D-ribofuranoside is a custom synthesis of a complex carbohydrate that can be used in glycosylation and polysaccharide synthesis. This product is a sugar with a CAS No. that has been modified with methylation, fluorination, and click chemistry. This product is synthesized by reacting the corresponding reactant monosaccharides with an acylating agent in the presence of a base to form 2,3,5-trihydroxybenzaldehyde esters. The 2,3,5-trihydroxybenzaldehyde esters are then reacted with an alcohol or phenol to form 2,4,6-trihydroxybenzalacetone derivatives which are converted into the desired product by hydrolysis.

N-Benzyl-3,5-dideoxy-3,5-imino-1,2-O-isopropylidene-D-arabinofuranose is a high purity custom synthesis sugar that has been modified with fluorination and glycosylation. The CAS number for this molecule is 51459-06-8 and it is an oligosaccharide. This molecule can be methylated or modified with other sugars to create complex carbohydrates.

D-Glucose hydrazon is a custom synthesis of complex carbohydrate. It is made by the reaction of Methylation, Click modification, and Fluorination with saccharide and sugar. The product is a white crystalline solid that is soluble in water.

1,4,6-Tri-O-galloylglucose is a synthetic carbohydrate that has been modified using glycosylation, methylation, and click modification. It is a complex carbohydrate with a high purity of 99.5%, and can be used in many applications including the synthesis of oligosaccharides. 1,4,6-Tri-O-galloylglucose can be fluorinated to create a product with increased resistance to hydrolysis.

L-Sorbosone is an antioxidant that can be used as a food additive or dietary supplement. It has been shown to have antioxidative properties and has the ability to inhibit oxidation reactions. The optimum concentration of L-sorbosone is 0.1 milligrams per liter and it is effective at inhibiting chemical reactions in a wide range of pH levels, from 2 to 8. L-Sorbosone belongs to the genus sorbose, which is a sugar alcohol that does not contain an aldehyde group. It also converts sorbose into dehydroascorbic acid and inhibits the enzyme activities of two important enzymes involved in cell culture, namely glutathione reductase and cytochrome p450, which are necessary for maintaining cellular redox balance.

The compound is an oligosaccharide with a fluorinated saccharide unit. It is synthesized by methylation of glycosylation and click modification of the sugar. Tert-Amyl 2-acetamido-3,4,6-tri-O-acetyl-2DGPA has been shown to be resistant to enzymatic digestion and hydrolysis by esterases. The compound can also be used as a fluorescent probe for studying carbohydrate metabolism.

D-myo-Inositol-2,3-O-cyclohexylidene is a lipase. It hydrolyzes esters and triglycerides, which are found in many natural and synthetic products. D-myo-Inositol-2,3-O-cyclohexylidene is more effective at hydrolyzing fats than porcine pancreatic lipase. This enzyme has been shown to be enantioselective for some solvents, such as vinyl acetate. D-myo-Inositol-2,3-O-cyclohexylidene also has the ability to produce butyrate from fatty acids.

D-Xylonic acid calcium salt hydrate is a product that is made from the hydrolysis of cellulose. It is a byproduct of the production of d-xylose and can be used as a nutritional supplement or an additive in animal feed. D-Xylonic acid calcium salt hydrate has been shown to have an uptake rate in aerobic conditions that is ten times higher than glucose, which makes it more economical for use in the production of d-xylose. D-Xylonic acid calcium salt hydrate can be catalyzed to produce yields for d-glucose and d-xylose, which are both important monosaccharides. The catalytic process also produces d-gluconic acid and aerobic oxidation produces d-xylose, making it possible to recycle these products.
