Novel carboxylate-based glycolipids: TLR4 antagonism, MD-2 binding and self-assembly properties

Read this paper in Sci Reports Abstract: New monosaccharide-based lipid A analogues were rationally designed through MD-2 docking studies. A panel of compounds with two carboxylate groups as phosphates bioisosteres, was synthesized with the same glucosamine-bis-succinyl core linked to different unsaturated and saturated fatty acid chains. The binding of the synthetic compounds to purified, functional recombinant human MD-2 was studied by four independent methods. All compounds bound to MD-2 with

Co-administration of Antimicrobial Peptides (AMPs) EnhancesToll-like Receptor 4 (TLR4) Antagonist Activity of a Synthetic Glycolipid

Full Paper Co-administration of Antimicrobial Peptides (AMPs) EnhancesToll-like Receptor 4 (TLR4) Antagonist Activity of a Synthetic Glycolipid Authors Francesco Peri, Fabio Alessandro Facchini, Helena Coelho, Stefania Enza Sestito, Sandra Delgado, Alberto Minotti, David Andreu, Jesús Jiménez-Barbero ChemMedChem Abstract   This study describes the effect of co-administration of antimicrobial peptides (AMPs) and synthetic glycolipid FP7, active in inhibiting inflammatory cytokine production caused by TLR4 activation and signaling. The co-administration of two

The Role of Carbohydrates in the Lipopolysaccharide (LPS)/Toll-Like Receptor 4 (TLR4) Signalling

Int. J. Mol. Sci. 2017, 18(11), 2318; doi:10.3390/ijms18112318   Abstract The interactions between sugar-containing molecules from the bacteria cell wall and pattern recognition receptors (PRR) on the plasma membrane or cytosol of specialized host cells are the first molecular events required for the activation of higher animal’s immune response and inflammation. This review focuses on the role of carbohydrates of bacterial endotoxin (lipopolysaccharide, LPS, lipooligosaccharide, LOS, and lipid A), in the interaction
