13-cis-Retinoyl b-D-glucuronide is a synthetic compound that can be modified to create a wide range of potential products. 13-cis-Retinoyl b-D-glucuronide is an oligosaccharide with a carbohydrate that may be glycosylated or polysaccharided. It has been custom synthesized and fluorinated, methylated, and monosaccharided. This product is extremely pure and can be used for many applications in the biomedical field.

L-Glycero-D-manno-heptose is a polymyxin B antimicrobial agent that has been shown to have significant activity against Gram-positive bacteria, including Staphylococcus aureus and Streptococcus pneumoniae. This compound also has an inhibitory effect on the growth of Gram-negative species such as Salmonella enterica. L-Glycero-D-manno-heptose inhibits the synthesis of bacterial cell wall peptidoglycan by binding to the terminal residues of oligosaccharides, which are linked to D-alanine in the peptidoglycan chain. The terminal residues of oligosaccharides are transferred from the lipid carrier to L-glycero-D manno heptose, forming a stable acylated glycoside. This reaction mechanism is similar to that of polymyxin B, but with a difference in reactivity due to steric hindrance.

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.

2-Hydroxypropyl-b-cyclodextrin is a water-soluble drug that is chemically stable in aqueous media. It has been shown to be safe for use in the eye, with no significant side effects. 2-Hydroxypropyl-b-cyclodextrin has been shown to have anti-inflammatory properties and will not cause hemolytic activity. 2-Hydroxypropyl-b-cyclodextrin binds to retinoic acid receptors, which are found on cells of the corneal surface and in human spermatozoa. The binding of retinoic acid inhibits the production of enzymes that break down retinoids and prevents cell proliferation. This agent also interacts with other cellular components such as proteins, lipids, carbohydrates, nucleic acids, and hormones.

Asialylated glycosphingolipid and precursor for ganglioside biosynthesis. The compound is a major glycosphingolipid in human neutrophils and is involved in the regulation of superoxides as well as nitric oxide. Moreover, lactosylceramide accumulates in atherosclerotic plaques and is also found elevated in familial hypercholesterolemia and polycystic kidney disease. Animal studies revealed that lactosylceramide induces hypertrophy in cardiomyocytes via signal transduction pathway that is oxygen-sensitive.

Sugammadex is a modified gamma-cyclodextrin specifically designed to reverse the effects of steroidal non-depolarizing neuromuscular blocking drugs, particularly rocuronium and vecuronium. In anesthesiology, it offers a novel approach to neuromuscular blockade reversal by directly encapsulating and inactivating these muscle relaxants. Sugammadex forms tight 1:1 complexes with free plasma rocuronium or vecuronium molecules, rapidly reducing their concentration at the neuromuscular junction. This mechanism allows for fast and predictable reversal of neuromuscular blockade, even from deep levels, without the need for anticholinesterases or antimuscarinic agents. Sugammadex has also shown promise in special populations, including pregnancy, pediatrics, and patients with renal or hepatic impairment.

Rengasin-4'-O-glucoside (RG4G) is a natural glycoside that belongs to the category of sugar derivatives. It has versatile uses and can be used as a building block for complex compounds, as well as in research chemicals, pharmaceuticals, and cosmetics. RG4G also has many applications in chemistry, including being used as a reagent or speciality chemical. RG4G is also an important intermediate in organic synthesis, which can be used to synthesize many useful compounds. The compound is often used as a scaffold for larger molecules.
