3-O-tert-Butyldiphenylsilyl-D-galactal is a glycosylation agent that can be used in the synthesis of oligosaccharides, sugar derivatives, and polysaccharides. It is synthesized by reacting 3-bromoacetophenone with D-galactal. This product is a white powder that is soluble in methanol and DMF. The CAS number for this product is 53533-71-3.

Forosamine is a spinosyn analog that has been shown to be an effective control agent against bacterial strains. It is a β-amino acid and has a chemical structure similar to the natural spinosyns. Forosamine has been shown to have a broad spectrum of activity against animal health-related bacteria, including those resistant to other antibiotics. Forosamine’s mode of action is not well understood, but it may involve the inhibition of protein synthesis. Forosamine's molecular modeling suggests that the molecule contains a hydroxyl group, which may be responsible for its antibacterial activity.

Losartan N1-glucuronide is a glucuronidated metabolite of losartan that is produced naturally in the human body. It is converted from losartan by the enzyme UDP-glucuronosyltransferase, which is found in humans and other animals. The rate of glucuronidation varies between individuals and is determined by genetic factors. Losartan N1-glucuronide has shown to be an effective inhibitor of angiotensin II, with an IC50 value of 1.4 μM. This inhibition can be reversed by dobutamine or recombinant human UGT2B7 enzyme, which are both competitive inhibitors of the enzyme UGT2B7. Magnetic resonance spectroscopy has been used to study the kinetic properties of this inhibitor and its effect on dobutamine-induced changes in cardiac function.

Propranolol-2-O-b-D-glucuronide is a metabolite of propranolol hydrochloride. It has been shown to have low bioavailability in humans and rats. Propranolol-2-O-b-D-glucuronide is eliminated via the kidney, with an elimination rate that is faster than the parent drug propranolol hydrochloride. The glucuronide conjugate of propranolol, which is found in urine samples, has been shown to be a potential biomarker for glomerular filtration rate and renal function.

Hyaluronate fluorescein is a large molecular weight, high-molecular weight, high-purity, highly modified carbohydrate. It is a synthetic oligosaccharide that has been chemically modified with methylation and saccharide. Hyaluronate fluorescein is synthesized using Click chemistry to add a fluorescent tag at the reducing end of the molecule. This product can be used for custom synthesis and glycosylation. Hyaluronate fluorescein is available in various sizes including 250kDa.

Cellotetraitol is a carbohydrate that has been isolated from the fungus Penicillium. It is a white crystalline solid that can be synthesized by hydrolyzing cellulose to cellobiose and then heating this sugar with acetic anhydride in the presence of sodium hydroxide. Cellotetraitol has two isomers, one of which is more active than the other. The most active form of cellotetraitol can be obtained as a crystalline solid at room temperature and has an optimal pH of 5. Cellotetraitol can be used for the synthesis of polyacrylamide gels, which are used to separate carbohydrates according to their size and charge.

NA3 N-glycan is a base that forms glycosidic bonds with other molecules. It has been shown to be pharmacologically active in tissues and has a safety profile. NA3 N-glycan is metabolized by the serine protease, which cleaves it from its glycosylated protein. The resulting molecule lacks a reactive group, which prevents it from forming toxic reactions with other molecules. NA3 N-glycan has been used for pharmacokinetic modeling and for mass spectrometric measurements of proteins in human serum and plasma.

1-Deoxy-1-nitro-L-galactitol is a compound that has been shown to inhibit serine protease and glutaminyl cyclase activity. It is commonly used in laboratory settings as a potassium substitute in media formulations. This compound belongs to the class of monosaccharides known as glutaminyl derivatives. It has been studied for its potential as an inhibitor of nafamostat, a serine protease inhibitor used in the treatment of pancreatitis and disseminated intravascular coagulation (DIC). Additionally, 1-Deoxy-1-nitro-L-galactitol has been investigated for its potential as a disinfectant and as an adrenergic receptor agonist. Preliminary studies have also suggested antiviral properties against certain viruses. Further research is needed to fully understand the potential applications of this compound.

Allyl 6-o-allyl-α-D-galactopyranoside is a medicinal compound with potential anticancer properties. It is an analog of α-D-galactopyranoside and has been shown to inhibit the activity of protein kinases, which are enzymes involved in cell signaling and regulation. This inhibition can lead to apoptosis, or programmed cell death, in cancer cells. Allyl 6-o-allyl-α-D-galactopyranoside has been studied extensively in Chinese medicine as a potential inhibitor of tumor growth and has also been found in human urine. This compound holds great promise as a natural alternative for cancer treatment and warrants further investigation into its therapeutic potential.

A fluorinated fructose analogue

4,7,8,9-Tetra-O-acetyl-N-acetyl-D-neuraminic acid methyl ester is a modified form of sialic acid. This compound is a glycosylation product that has been modified with methyl groups and fluorine atoms. The fluorination of the molecule increases its stability and prevents it from being hydrolyzed by enzymes such as β-galactosidase. 4,7,8,9-Tetra-O-acetyl-N-acetyl-D-neuraminic acid methyl ester is often used in the synthesis of polysaccharides and oligosaccharides for medical purposes. This compound can be custom synthesized for research purposes or to meet special requirements.
