T-5342126 is a toll-like receptor 4 (TLR4) antagonist. It reduces LPS-induced production of nitric oxide (NO) in RAW 264.7 cells (IC50=27.8 μM), as well as decreases LPS-induced IL-8, TNF-α, and IL-6 production in isolated human whole blood (IC50s=110.5, 315.6, and 318.4 μM, respectively). T-5342126 (82 mg/kg) reduces ethanol intake and the abundance of ionized calcium-binding adapter molecule 1 (Iba1), a marker of microglial activation, in the central nucleus of the amygdala in ethanol-dependent mice.

Liriodendrin is an orally effective lignan compound with anti-inflammatory, antioxidant, and anti-platelet aggregation activities. Liriodendrin is isolated and extracted from Sargentodoxae caulis and Linaria vulgaris. Liriodendrin regulates the expression of genes related to inflammation and cellular metabolism by inhibiting the NF-κB, PI3K/Akt, and TLR4 signaling pathways, or by activating the PI3K-DDX18 pathway. Liriodendrin increases the expression of HSF1 and HSP27 without cytotoxicity. Liriodendrin is used in studies on ulcerative colitis, myocardial ischemia-reperfusion injury, sepsis-induced acute lung injury, and chronic endometritis [4] .

Synonyms: G2013 sodium
Guluronic acid (G2013) sodium is an orally active oxidative stress regulator and anti-inflammatory agent that exerts pharmacological effects by down-regulating various pro-inflammatory and oxidative stress-related genes (such as TLR4, NF-κB, iNOS, etc.) and inhibiting the activities of COX-2, MMPs and VEGF. Low-dose Guluronic acid sodium up-regulates the expression of immunoregulatory genes SHIP1 and SOCS1, thereby effectively inhibiting cancer-related inflammation, tumor angiogenesis, cell adhesion and metastasis, while reducing the accumulation of immunosuppressive cells.

Synonyms: LPS, from bacterial (Klebsiella pneumoniae)
Lipopolysaccharides, from Klebsiella pneumoniae (LPS, from bacterial (Klebsiella pneumoniae)) are lipopolysaccharide endotoxins and TLR4 activators derived from Klebsiella pneumoniae, and are classified as S-type LPS. Lipopolysaccharides, from Klebsiella pneumoniae exhibit a typical three-part structure: O-antigen, core oligosaccharide, and lipid A. Lipopolysaccharides, from Klebsiella pneumoniae may participate in bacterial immune evasion by inhibiting complement-mediated killing and suppressing the host's secretion of antimicrobial peptides, thereby allowing the bacteria to escape immune defenses. Lipopolysaccharides, from Klebsiella pneumoniae possess high viscosity and resistance to serum-mediated killing, which may lead to sepsis. Lipopolysaccharides, from Klebsiella pneumoniae can be used to construct Acute Lung Injury Model .
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.

Synonyms: LPS, from Pseudomonas aeruginosa (10)
Lipopolysaccharides from P. aeruginosa (Pseudomonas aeruginosa) 10 are lipopolysaccharide endotoxins and TLR4 activators derived from Pseudomonas aeruginosa 10, and are classified as S-type LPS. Lipopolysaccharides from P. aeruginosa 10 exhibit a typical three-part structure: O-antigen, core oligosaccharide, and lipid A. The lipopolysaccharides of P. aeruginosa 10 have a fatty acid composition distinct from common enterobacteria, an exceptionally high degree of phosphorylation (triphosphate residues have been detected), and a unique outer region of the core oligosaccharide. Additionally, their O-specific side chains are typically rich in novel aminosugars. Lipopolysaccharides from P. aeruginosa 10 demonstrate susceptibility to viruses, with the level of susceptibility determined by the content of high molecular weight polysaccharides in their composition. The absence of high molecular weight polysaccharides increases their sensitivity to bacteriophages .
