TLR4-C34

Toll-like receptor 4 (TLR4) is activated by lipopolysaccharide (LPS), with LPS-binding protein, to initiate an innate immune response, which typically includes increased expression of TNFalpha. TLR4-C34 is a 2-acetamidopyranoside that inhibits TLR4 signaling in enterocytes and macrophages in vitro when used at 10 µM. It does not affect signaling through either TLR2 or TLR9. TLR4-C34, used at 1 mg/kg in vivo, also reduces systemic inflammation in mouse models of endotoxemia and necrotizing enterocolitis. It markedly decreases the basal expression of TNFalpha, as well as LPS-induced iNOS and TNFalpha expression, in intestinal tissue isolated from patients with necrotizing enterocolitis.Formal Name: 1-methylethyl 2-(acetylamino)-2-deoxy-alpha-D-glucopyranoside, 3,4,6-triacetate.
