Classification of Carbohydrates

Lipopolysaccharides, from E. coli O55:B5 (LPS, from Escherichia coli (O55:B5)) are endotoxins and TLR4 activators extracted from Escherichia coli (E. coli O55:B5) and are classified as S (smooth) type LPS. Lipopolysaccharides, from E. coli O55:B5 possess the typical three-part structure: O-antigen, core oligosaccharide, and lipid A. Lipopolysaccharides, from E. coli O55:B5 activate TLR-4 in immune cells, exhibit high pyrogenicity, and demonstrate dose and serotype specificity. Lipopolysaccharides, from E. coli O55:B5 can be widely used to induce cellular inflammation and establish animal models related to inflammation.
It is recommended to prepare a solution with concentration ≥2 mg/mL. Vortex thoroughly for more than 10 minutes. Due to the adsorption characteristics of LPS, silanized container or low adsorption centrifuge tubes should be used for aliquoting and storage, and mix thoroughly before use.

2-Deoxy-D-glucose is a glucose analog that acts as a competitive inhibitor of glucose metabolism, inhibiting glycolysis via its actions on hexokinase.

SBE-β-CD is a sulfobutylether β-cyclodextrin derivative used as an excipient or a formulating agent to increase the solubility of poorly soluble agents.

ATP (Adenosine 5'-triphosphate) is a central component of energy storage and metabolism in vivo. ATP provides the metabolic energy to drive metabolic pumps and serves as a coenzyme in cells. ATP is an important endogenous signaling molecule in immunity and inflammation. ATP can activate the NLRP3 inflammasome and induce IL-1β and chemokines secretion. ATP has anti-bacterial infection effects and can protect mice against bacterial infection in mice.

Etoposide (VP-16; VP-16-213) is an anti-cancer chemotherapy agent. Etoposide inhibits topoisomerase II, thus stopping DNA replication. Etoposide induces cell cycle arrest, apoptosis and autophagy.

5-BrdU (BrdU) is a nucleoside analog that competes with thymidine for incorporation into DNA. 5-BrdU is commonly used in the detection of proliferating cells.

2-NBDG is a fluorescently-labeled deoxyglucose analog that is used primarily to directly monitor glucose uptake by living cells and tissues. It is also used as a topical contrast reagent for the detection of neoplasia. 2-NBDG can be used in real-time confocal, high-resolution, or wide-field fluorescence microscopy as well as in flow cytometry. The probe can be excited by the Argon laser at 488 nm to give the environment-sensitive fluorescence. It has lower photostability than the rhodamine-based fluorescent probes.

Conduritol B epoxide is an irreversible covalently bound acid β-glucosidase (GCase) inhibitor.

Bleomycin sulfate is a DNA synthesis inhibitor. Bleomycin hydrochloride is a DNA damaging agent. Bleomycin sulfate is an antitumor antibiotic.

G-418 disulfate (Geneticin sulfate), is an aminoglycoside antibiotic, inhibits protein synthesis in eukaryotes and prokaryotes. G-418 disulfate is commonly used as a selective agent for eukaryotic cells.

Puromycin dihydrochloride (CL13900 dihydrochloride), an aminonucleoside antibiotic, inhibits protein synthesis.

Digitonin, a glycoside obtained from Digitalis purpurea, could increase cell permeability by binding to cholesterol molecules and reduce tumor growth. Digitonin is an natural detergent.

Methyl-β-cyclodextrin (Methyl-beta-cyclodextrin) is a cyclic heptasaccharide used to deliver hydrophobic agents based on its property of solubilizing non-polar substances. Methyl-β-cyclodextrin is also extensively used as a cholesterol-depleting reagent. Methyl-β-cyclodextrin strongly reduces clathrin-dependent endocytosis. Methyl-β-cyclodextrin blocks cell migrasome formation.

Hygromycin B is an aminoglycoside antibiotic active against prokaryotic and eukaryotic cells.

D-Galactose is a natural aldohexose and C-4 epimer of glucose.

HP-β-CD ((2-Hydroxypropyl)-β-cyclodextrin) is a widely used drug delivery vehicle to improve the stability and bioavailability.

Sodium carboxymethyl cellulose (Viscosity:800-1200 mPa.s) is the sodium salt of cellulose arboxymethyl and frequently used as viscous agent, paste and barrier agent.

AICAR (Acadesine) is an adenosine analog and a AMPK activator. AICAR is also an autophagy, YAP and mitophagy inhibitor. AICAR regulates the glucose and lipid metabolism, and inhibits proinflammatory cytokines and iNOS production. AICAR inhibits autophagy through a mechanism independent of AMPK activity.

Neomycin sulfate, an aminoglycoside antibiotic, exerts antibacterial activity through irreversible binding of the nuclear 30S ribosomal subunit, thereby blocking bacterial protein synthesis. Neomycin sulfate is a known phospholipase C (PLC) inhibitor. Neomycin sulfate potently inhibits both the nuclear translocation of angiogenin and angiogenin-induced cell proliferation and angiogenesis. Neomycin sulfate inhibits IP3-mediated Ca²⁺ release, MgATP-dependent Ca²⁺ uptake, and electrical excitation-evoked skeletal muscle Ca²⁺ transients. Neomycin sulfate depletes gut microbiota in specific mouse models, causes hearing impairment, and kidney damage with prolonged exposure. Neomycin sulfate can be used for the research of cancer.

IPTG is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce protein expression where the gene is under the control of the lac operator.
