tlr4/md-2

Procyanidin B1, isolated from commonly eaten fruits, binds to the TLR4/MD-2 complex and has anti-inflammatory activity.

L48H37 is a chemically stable analog of Curcumin. It exhibits potent inhibitory properties against myeloid differentiation protein 2 (MD2), acting as a specific inhibitor. Its mechanism involves inhibiting the interaction and signaling transduction of LPS-TLR4/MD2. L48H37 is primarily utilized in sepsis and lung injury research [1].

Neoseptin-3 is a novel small molecule agonist of mouse mTLR4/MD2 with EC50=18.5 μM that does not activate human TLR4/MD2.

1. Isofraxidin (Phytodolor) protects leukemia cells from radiation-induced apoptosis via ROS/mitochondria pathway in a p53-independent manner. 2. Isofraxidin has a protective effect against LPS-induced ALI, and the protective effect of Isofraxidin seems to result from the inhibition of COX-2 protein expression in the lung, which regulates the production of PGE2. 3. Isofraxidin possesses significant analgesic and anti-inflammatory activities that may be mediated through the regulation of pro-inflammatory cytokines, TNF-α and the phosphorylation of p38 and ERK1/2.

1. Atractylenolide-I has an anti-inflammatory effect by inhibiting TNF-α and IL-6 production; ameliorates sepsis syndrome, liver and kidney functions by reduction of pro-inflammatory cytokines and LPS. 2. Atractylenolide-I significantly sensitizes the res

MD2-TLR4-IN-1 is a myeloid differentiation protein 2/toll-like receptor 4 (MD2-TLR4) complex inhibitor.

Atractylenolide I (Standard) is a reference standard for research and analysis in studies involving Atractylenolide I. 1. Atractylenolide-I has an anti-inflammatory effect by inhibiting TNF-α and IL-6 production; ameliorates sepsis syndrome, liver and kidney functions by reduction of pro-inflammatory cytokines and LPS. 2. Atractylenolide-I significantly sensitizes the response of MyD88(+) EOC cells to paclitaxel by blocking MD-2-mediated TLR4/MyD88 signaling.

Procyanidin B1 (Standard) is a reference standard for research and analysis in studies involving Procyanidin B1. Procyanidin B1, isolated from commonly eaten fruits, binds to the TLR4/MD-2 complex and has anti-inflammatory activity.

Lipopolysaccharides, from S. marcescens (Serratia marcescens), are endotoxins derived from the bacterium Serratia marcescens, functioning as TLR-4 activators and classified as S type LPS. These compounds activate the immune system through pathogen-associated molecular patterns (PAMPs) and stimulate the secretion of chemokines. They feature a typical tripartite structure consisting of the O-antigen, core oligosaccharide, and Lipid A. Lipopolysaccharides from S. marcescens promote NF-κB activation in mouse cells via Toll-like receptor (TLR4)/MD-2 pathways. Additionally, these lipopolysaccharides can induce apoptosis in host immune cells, thereby suppressing the host's innate immunity.
