TLR2

A natural, noncaloric sweetener with a potency 300 times more than that of regular sucrose. Exhibits transepithelial p-aminohippurate transport via organic anion transport system interference.

D-Mannuronic Acid is a blocker of the TLR2 and TLR4 downstream signaling pathway. D-Mannuronic Acid effectively inhibits mRNA expression of MyD88 and p65, major subunit of nuclear factor-kappaB.

(Rac)-Shikonin (Anchusin) is a natural red naphthoquinone pigment, has antimicrobial, anti-tumor, and anti-inflammatory effects; a purified shikonin preparation is widely used for the production of medicinals, cosmetics, and some food products; shikonin also enters into the antiinflammatory ointment and cream compositions used for the treatment of burns. It can suppress the cell viability, adhesion, invasion and migratory ability of MGC-803 cells through TLR2- or NF-κB-mediated pathway.

Corilagin has anti-inflammatory activity. Corilagin has a significant antitumour potential and lower toxicity in normal cells in vitro.Corilagin can enhance the cytotoxicity of both cisplatin and doxorubicin on the Hep3B hepatoma cells.Corilagin has antiviral activity, reduces the cytotoxicity induced by EV71 or CA16 on Vero cells with and IC50 value of 5.6 and 32.33 μg mL, respectively. Corilagin shows the potential to protect against HSV-1-induced encephalitis, and the beneficial effects may be mediated by inhibiting TLR2 signaling pathways.Corilagin has antifibrotics property and is potentiated in treating idiopathic pulmonary fibrosis(IPF), attenuates bleomycin-induced epithelial injury and fibrosis via inactivation of oxidative stress, proinflammatory cytokine release and NF-κB and TGF-β1 signaling. Solvent:Pyridine, Methanol, Ethanol, etc.

Sparstolonin B, a selective TLR2 and TLR4 antagonist, is an isocoumarin compound isolated from the tubers of Sparganium stoloniferum and Scirpus yagara with anti-HIV, anticancer, antitumour and anti-inflammatory activities, inhibits selective Toll-like receptors, inhibits free fatty acids It inhibits selective Toll-like receptors, inhibits free fatty acid palmitate-induced chondrocyte inflammation and attenuates post-traumatic arthritis in obese mice, and inhibits lipopolysaccharide-induced inflammation in 3T3-L1 adipocytes, which can be used for validation and mammary carcinoma studies.

PSMα3 is a peptide compound that can be utilized to induce tolerance in dendritic cells (DCs) for DC vaccination strategies. It effectively penetrates and modulates human monocyte-derived DCs by modifying the maturation process induced by TLR2 or TLR4. Additionally, PSMα3 inhibits the production of both pro- and anti-inflammatory cytokines and decreases antigen uptake. Notably, PSMα3 is a significant virulence factor released by the most pathogenic strains of methicillin-resistant Staphylococcus aureus (MRSA).

(-)-Alkannin (Shikonin) is a natural red naphthoquinone pigment, has antimicrobial, anti-tumor, and anti-inflammatory effects; a purified shikonin preparation is widely used for the production of medicinals, cosmetics, and some food products; shikonin also enters into the antiinflammatory ointment and cream compositions used for the treatment of burns. It can suppress the cell viability, adhesion, invasion and migratory ability of MGC-803 cells through TLR2- or NF-κB-mediated pathway.

Zymosan A, a polysaccharide from Saccharomyces cerevisiae (brewer's yeast), is a TLR2 agonist that promotes regeneration of ISCs from intestinal stem cells after radiation injury by up-regulating ASCL2 through the TLR2 signaling pathway and the Wnt signaling pathway.Zymosan A stimulates immune responses and induces inflammation , anorexia and elevated body temperature, and also inhibits the gap junction protein connexin 43 in human corneal fibroblasts and causes corneal stromal damage.
