General description

TLR4-IN-C34 is an inhibitor of toll-like receptor 4 (TLR4) in vitro and in vivo.

Application

TLR4-IN-C34 has been used as an inhibitor in the HFD-feeding mice to verify the aforementioned in vitro pathway (stearic acid/LDH-a/cytokines) in vivo.

Biochem/physiol Actions

TLR4-IN-C34 is a potent and specific inhibitor of toll-like receptor 4 (TLR4), which inhibits TLR4 signaling in vivo and in vitro. TLR4-IN-C34, also known as C34, is an aminomonosaccharide that inhibits TLR4 signaling by docking with the hydrophobic pocket of the TLR4 co-receptor, myeloid differentiation protein-2 (MD-2). C34 has been shown to diminish the severity of experimental necrotizing enterocolitis (NEC).

The low-molecular weight isopropyl 2-acetamido-α-glucoside 16 (C34) inhibits toll-like receptor 4 (TLR4) in enterocytes and macrophages in vitro, and reduces systemic inflammation in mouse models of endotoxemia and necrotizing enterocolitis. We used a copper(II)-mediated solvolysis of anomeric oxazolines and an
