3'-Sialyl Lewis A-PAA-biotin is a carbohydrate that is used as a research tool for investigating the structure and function of glycoproteins, glycolipids, and glycosaminoglycans. It contains 3'-sialic acid linked to the terminal β-D-galactopyranosyl residue of a poly(amino acid) backbone. This product has been synthesized by custom synthesis and contains high purity with a custom synthesis.

1-D-4-O-Methyl-myo-inositol is a compound that belongs to the group of biological compounds. It has been shown to have hypoglycemic effects in a model system and to inhibit 3t3-l1 preadipocyte differentiation. This compound also inhibits the activity of enzymes involved in metabolic pathways, and has an effect on lipid metabolism in kidney beans. 1-D-4-O-Methyl-myo-inositol has been shown to have antiobesity properties as well as antihyperglycemic activities.

Trehalose-6,6'-dibehenate (TDB) is a novel synthetic lipid that has been shown to have beneficial effects in the treatment of inflammatory bowel disease. This compound may act as an anti-inflammatory agent by inhibiting toll-like receptor 4 (TLR4)-mediated signaling and TLR4-dependent production of proinflammatory cytokines. TDB also inhibits HIV infection by interfering with CD4+ T cell function and decreasing the number of CD4+ cells in the gut. In addition, TDB has been shown to be effective against lps-induced inflammatory response in cell culture.

L-Glycero-L-galacto-heptose is a cyclitol that is structurally similar to glycerol and galactose. It has been found in the Australian sea urchin Strongylocentrotus franciscanus. L-Glycero-L-galacto-heptose can be synthesized by reacting methyl glycosides with calcium ions. This reaction produces an electrophoretic mobility that is greater than that of glycerol, which may be due to the greater degree of hydrogen bonding between methyl glycosides and calcium ions. The presence of hydroxyl groups on the sugar residue allows for the formation of hydrogen bonds with neighboring molecules. These interactions lead to a conformation that is different from other cyclitols, such as D-glycero-D-galactopyranose, which has no hydroxyl group on its sugar residue.

Methyl a-D-fucopyranoside is a monoclonal antibody that binds to the O-antigen of the polysaccharide chain. It is a synthetic trisaccharide consisting of an o-antigen, an α-linked D-fucose residue, and an α-linked galactose residue. This antibody interacts with the serologic subtypes of Group A Streptococcus, but not with other serogroups. Methyl a-D-fucopyranoside utilizes conformational epitopes and disaccharides which are not accessible to other antibodies in order to bind to the o-antigen. The o-antigen is composed of two serologically distinct regions: one region for binding by anti-A antibodies, and another for binding by anti-B antibodies.

Conduritol D (CD) is a natural product that has been isolated from the pancreas of rats. It is homochiral, and it has been shown to be active in the treatment of diabetic patients. CD has a hydroxy group at C-4' and an alcohol group at C-5'. The functional groups are acetylated at C-3', which may make this compound more potent than other similar compounds with different functional groups. It is also synthesized stereoselectively, making it a selective molecule. CD has been shown to have pharmacokinetic properties that may be beneficial for treating diabetes.
