It is a carbohydrate (saccharide) that is modified by fluorination, methylation and glycosylation. The CAS number for this carbohydrate is 535745-06-4. This product has the following properties: Oligosaccharide, sugar, complex carbohydrate.

(R)-Ketoprofen b-D-glucuronide is a synthetic modified sugar that is produced by the glucuronidation of ketoprofen, a nonsteroidal anti-inflammatory drug. The modification of ketoprofen with glucuronic acid can be achieved through an enzymatic process, which is catalyzed by UDP-glucuronyltransferase. This modification increases the solubility of ketoprofen and its ability to penetrate cells. (R)-Ketoprofen b-D-glucuronide has been shown to have antibacterial properties against Gram positive bacteria such as Staphylococcus aureus and Streptococcus pyogenes. It has also shown antiviral activity against HIV-1 due to its inhibition of reverse transcriptase, which is an enzyme important for viral replication.

Inhibitor of lysosomal acid β-glucosidase (GlcCerase/glucocerebrosidase) with IC50 in nanomolar range for wildtype and mutant enzyme. It behaves as pharmacological chaperon by binding to instable GlcCerase active site at neutral pH values and facilitating the protein folding. In acidic lysosomes, isofagomine gets release from the enzyme active site. This results in increased levels of functional glucocerebrosidase and brings therapeutic benefits to patients with Gaucher disease.

D-Arabinopyranosyl thiosemicarbazide is a synthetic compound. It has been shown to be effective in the synthesis of oligosaccharides and sugars, as well as glycosylation reactions. This product can be used in fluorination, methylation, and other custom synthesis reactions. D-Arabinopyranosyl thiosemicarbazide is also useful for click modification of complex carbohydrates. The purity of this product is high and it can be modified with various functional groups.

Methyl 2-acetamido-2-deoxy-6-O-(b-D-galactopyranosyl)-a-D-glucopyranoside is a custom synthesis, modification and fluorination of a monosaccharide. The saccharide is modified with methylation and click modification at the 6th carbon position. This product is designed for use in the synthesis of complex carbohydrates.

Main metabolite of antiretroviral drug Abacavir with potent activity against human immunodeficiency virus type 1 (HIV-1). Abacavir is eliminated by hepatic metabolism to two major metabolites: 5’-glucuronide formed by uridine diphosphate glucuronyl transferase and 5’-carboxylate formed by cytosolic alcohol dehydrogenase.

4-Hydroxypropofol-4-O-b-D-glucuronide (HPG) is a synthetic carbohydrate with a 4,5-dihydroxypropyl group at C2 and an O-glycosidic bond between the hydroxyl group at C1 and the b position of a glucuronic acid. HPG is used in the synthesis of complex carbohydrates and saccharides. It can be methylated in order to produce 5,6-dimethoxycarbonyloxypropyl glycosides or glycosylated to produce mannosides. HPG has been synthesized by click modification from 4,5-dihydroxypropionic acid.

Phenyl 2,3-di-O-benzyl-6-deoxy-b-D-thioglucopyranoside is a synthetic glycosylated sugar with a fluorinated benzene ring. It is used as an intermediate in the synthesis of oligosaccharides, polysaccharides and saccharides. Phenyl 2,3-di-O-benzyl-6-deoxy-b-D-thioglucopyranoside has an appearance of a white powder and a melting point of around 100°C. This compound has been evaluated for its purity and quality by analytical methods such as high performance liquid chromatography (HPLC), gas chromatography (GC) and nuclear magnetic resonance (NMR).

Maltotetraose-APD-HSA is a complex carbohydrate with a high purity. Maltotetraose-APD-HSA is a synthetic oligosaccharide that has been modified by glycosylation, methylation, and fluorination. It is an alpha 1,4 linked maltotetraose that has been conjugated to HSA. Maltotetraose-APD-HSA has the CAS number 113789-04-8 and its molecular weight is 495.7 Da. Maltotetraose-APD-HSA can be found in the monosaccharides saccharide and carbohydrate categories.

GT1c oligosaccharide (free acid) has a core tetrasaccharide structure (Galβ1,3GalNAcβ1,4Galβ1,4Glc) with three sialic acid residues (NeuAc) linked α2,8/α2,8/α2,3 to the inner galactose residue (Ledeen, 2009). A monoclonal antibody, established against the chick neural tube, was shown to recognize the trisialosyl residue, NeuAca2-8NeuAca2-8NeuAca2-3-R GT1c ganglioside in the cerebral cortex of fetal rats (Hirabayashi, 1989). This unusual multisialo ganglioside was recognised in chicken optic lobes and cerebrum, during embryonic development (Rosner, 1980) and in fish brains (Yu, 1980).

1,3-O-Benzylidene-L-erythritol is a potent inhibitor of the intestinal maltase. It has two diastereomers, one of which is more potent than the other. The more potent diastereomer inhibits both the maltase and L-arabinose isomerase enzymes in the intestine. This inhibition prevents digestion of complex carbohydrates such as starch and sucrose into simple sugars that can be absorbed by the body. 1,3-O-Benzylidene-L-erythritol also inhibits salacinol synthase and thiosugar synthetases from bacteria and plants, preventing synthesis of these important compounds.
