N-Nonyldeoxygalactonojirimycin (NDGJ) is a novel antiviral agent that inhibits the activity of viral enzymes, such as polymerase chain reaction and reverse transcriptase. NDGJ has been shown to inhibit the replication of hepatitis viruses in primary cells and human macrophages. The drug also inhibits the replication of human pathogens, such as HIV-1, herpes simplex virus type 1, and cytomegalovirus in cell culture. NDGJ has an effect on hydrophobic amino acids in protein synthesis by binding to them and preventing their attachment to the ribosomal surface. This leads to cell lysis through a process called osmotic shock.

An anhydro thio sugar

This beta-cyclodextrin (β-CD) derivative is a functionalized cyclic oligosaccharide composed of seven glucose units, characterized by a hydrophilic exterior and a lipophilic cavity (bigger than α-CD and smaller than γ-CDs), which allows it to encapsulate various guest molecules. This structural feature facilitates its use in multiple applications, including pharmaceuticals, food enhancement, and cosmetics. In the pharmaceutical industry, it enhances the solubility and stability of poorly water-soluble drugs, improving their bioavailability and efficacy while also masking unpleasant tastes. The food sector utilizes it as a stabilizer for flavors, colors, and nutrients, extending shelf life by protecting sensitive ingredients from degradation. In cosmetics, it serves as a complexing agent for fragrances and active components, ensuring their stability and controlled release. Its use expands to many other fields, including nanotechnology for drug delivery systems, environmental remediation for extracting organic pollutants, textiles for slow-release fragrances, and analytical chemistry for chiral separation.

UDP-D-glucuronide ammonium salt is a drug that is used for the treatment of estrogen-dependent cancers. It is an inhibitor of human UDP-glucuronosyltransferase, an enzyme that catalyzes the glucuronidation of estrone and other substrates. The binding affinity of UDP-D-glucuronide ammonium salt can be increased by mutating the enzyme to increase its kinetic rate. This drug has been shown to inhibit estrogen production in recombinant human liver cells as well as in human liver cells. Mutations in the gene encoding this enzyme have also been associated with variations in estrogen levels, specifically high rates.

Glycogen is a highly branched polysaccharide of glucose that serves as a form of energy storage in animals and fungi. It is the main storage form of glucose in the body.  In humans, glycogen is made and stored primarily in liver and muscle cells and functions as the second most important energy storage molecule to fat which is held in adipose tissue. Glycogen is analogous to starch and has a structure similar to amylopectin, but is more extensively branched and compact than starch. It occurs as granules in the cytosol/cytoplasm in many cell types, and plays an important role in the glucose cycle.

3-Phenyl-2-propenylbeta-D-glucopyranoside is a flavonoid that has been shown to have inhibitory properties. It has been used as an analytical method for the diagnosis of bronchial reactivity. The high resistance of 3-phenyl-2-propenylbeta-D-glucopyranoside to oxidation and reduction make it an interesting candidate for antiinflammatory agents. When testing the effects of this compound on human bronchial tissue, it was found that 3-phenyl-2-propenylbeta-D-glucopyranoside inhibited allergic symptoms by inhibiting the release of inflammatory mediators such as histamine and leukotrienes, which are released in response to allergens and other irritants in the airways. The use of this compound may be useful in the treatment of asthma patients who suffer from allergic reactions to dust, pollen, or animal dander.
