Description

TLR4-C34 is a TLR4 inhibitor that inhibits TLR4 signaling in enterocytes and macrophages in vitro. The innate immune receptor toll-like receptor 4 (TLR4) is a pattern recognition receptor expressed in both hematopoietic and non-hematopoietic cells. C34 is a 2-acetamidopyranoside that inhibits TLR4 in IEC-6 enterocytes and RAW264.7 macrophages in vitro at a dosage of 10μM. Pretreatment with 1mg/kg C34 30 minutes before LPS (3mg/kg) injection significantly reduced luciferase activity in mice. In a mouse model of experimental necrotizing enterocolitis (NEC), oral gavage of C34 (1mg/kg/day) for 4 days attenuated the severity of NEC as demonstrate by marked preservation of the intestinal mucosa, downregulation of pro-inflammatory iNOS expression, and reduced NEC severity score. C34 at 10μM inhibited TLR4 signaling ex vivo in human tissues isolated from infants with NEC.
