Dehydroclindamycin is a semisynthetic antibiotic that belongs to the class of antibiotics known as lincosamides. It is used in clinical treatment for bacterial infections. Dehydroclindamycin acts by interfering with the bacterial ribosome and prevents the formation of proteins required for cell division. This drug may be susceptible to degradation by hydrolysis or oxidation, which can lead to impurities. Dehydroclindamycin is produced by hydrogenation of clindamycin hydrochloride using a Raney nickel catalyst, followed by chromatography. The spectrum of dehydroclindamycin consists of antibacterial activity against gram-positive bacteria such as Staphylococcus aureus and Enterococcus faecalis and gram-negative bacteria such as Escherichia coli and Klebsiella pneumoniae.

Glucosamine is a hexose sugar that is an amino sugar and a precursor in the biosynthesis of glycoproteins. It also acts as an intermediate for the synthesis of other non-carbohydrate natural products. 6-O-Acetyl-2-azido-3,4-di-O-benzyl-2-deoxyglucopyranose is a glucosamine derivative that has been synthesized from trifluoroacetic acid and piperidine. The acetyl group on this compound makes it soluble in water, which allows for its use in pharmaceuticals and other applications.

Nistose trihydrate is a polysaccharide that is found in the cell walls of plants, including inulin and d-biotin. It has been shown that nistose trihydrate can be used as an additive to mammalian cells to improve enzymatic reactions. In addition, nistose trihydrate can be used as a food additive to reduce cholesterol levels and modulate blood sugar levels. Nistose trihydrate also has antimicrobial activity against staphylococcus, which are gram-positive bacteria.

5-Aminosalicylic acid (5-ASA) is an anti-inflammatory drug that belongs to the class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). 5-ASA is an acidic compound that is a metabolite of salicylic acid. It is used in the treatment of rheumatoid arthritis, osteoarthritis, and other inflammatory diseases. The preparation of 5-ASA involves homogenizing liver tissue and then extracting it with water. This extract can be chromatographed using preparative high performance liquid chromatography (HPLC) or spectroscopically analyzed by mass spectrometry. 5-ASA has been shown to have hepatoprotective effects in rats when given at a dose of 400 mg/kg body weight by intraperitoneal injection.

α-GalCer analog 8 is a high purity, custom synthesis, synthetic α-galactocerebrosidase enzyme that has been modified to include 8 fluorine atoms. The enzyme is glycosylated at the N-terminal and methylated at the C-terminal. The modification of this enzyme with an oligosaccharide and monosaccharide moiety improves its stability in vivo. α-GalCer analog 8 is used for the treatment of Gaucher's disease, which is caused by the accumulation of complex carbohydrates in the body. This condition can be managed using α-GalCer analog 8 because it hydrolyzes these complex carbohydrates into their monosaccharides.

NA4 is a n-glycan with an average molecular weight of about 3.5 kDa. NA4 is found in the blood and urine of human beings and other mammals, as well as in the milk from cows. It is a major component of mucus secreted by the respiratory tract, and it can be found in the outer layer of the skin. NA4 contains a single N-acetylglucosamine (NAG) residue at its reducing end.

Methyl 3,4-O-isopropylidene-L-threonate is a chromatographic chiral compound that is synthesized by the reaction of malonate and aspartyl amide. This product can be used to determine the stereochemistry of other chiral compounds. It is an endocannabinoid that has been found to have anti-inflammatory activities in animals. Methyl 3,4-O-isopropylidene-L-threonate has also been shown to have antiobesity effects in mice fed a high fat diet and may be used as a synthetic carbohydrate replacement for diabetics.

D-Galactose-2-D is an anticancer agent that has been shown to inhibit the activity of kinases, which are enzymes involved in cell signaling pathways. It is a derivative of D-galactose and has been found in human urine. D-Galactose-2-D has demonstrated potent antitumor effects against various cancer cell lines, including Chinese hamster ovary cells and human colon carcinoma cells. This compound induces apoptosis, or programmed cell death, in cancer cells by inhibiting the activity of key proteins involved in cell survival. Additionally, D-Galactose-2-D has been found to be a potent inhibitor of capsaicin-induced activation of kinase, suggesting its potential as a therapeutic agent for inflammatory conditions.

2-Deoxy-3,4-O-isopropylidene-D-arabinopyranose is a synthetic sugar that has a high purity and can be custom synthesized. It is an oligosaccharide with a methylation and fluorination modification. This sugar can be used in glycosylation reactions to produce polysaccharides or complex carbohydrates. 2-Deoxy-3,4-O-isopropylidene-D-arabinopyranose is also used in click modifications. The CAS number for this compound is 5263038-92-2.

1,2:5,6-Di-O-isopropylidene-L-chiro-inositol is a custom synthesis that can be modified by fluorination, methylation and click modification. The product is a monosaccharide and an oligosaccharide. It is also a synthetic saccharide and a polysaccharide. The product can be glycosylated or sugar modified with carbohydrates such as complex carbohydrate to form 1,2:5,6-Di-O-isopropylidene-L-chiro-inositol.
