Quorum sensing-IN-2	Bacterial	Infection
Quorum sensing-IN-2 (compound 23e) is a quorum sensing inhibitor, which can reduce the pathogenicity of bacteria without affecting bacterial growth. Quorum sensing-IN-2 inhibits bacterial infections with little hemolytic activity. Quorum sensing-IN-2 shows synergistic effect with Ciprofloxacin (HY-B0356) in the bacteremia model infected with P. aeruginosa PAO1 .

HY-P2957

Hyaluronate lyase	Biochemical Assay Reagents	Metabolic Disease
Hyaluronate lyase can cleat hyaluronate (HA) and produce unsaturated disaccharides through a β-elimination reaction. The resulting disaccharides further trigger the downstream pathway and catalyze the next reaction. Hyaluronate lyase helps Streptococcus dysgalactiae subsp.equisimilis (SDSE) acquire nutrients from the host, causing bacterial pathogenicity .

HY-162376

T3SS-IN-4	Bacterial	Infection
T3SS-IN-4 (Compound Z-8) is a T3SS inhibitor that can inhibit the expression of Xanthomonas oryzae pv oryzae (X_oo) T3SS-related genes without affecting bacterial growth. T3SS-IN-4 can effectively reduce the hypersensitive response (HR) induced by X_oo in tobacco and lower the pathogenicity of X_oo in rice .

Lipopolysaccharides, from S. enterica serotype typhimurium LPS, from Salmonella enterica (Serotype typhimurium)	Toll-like Receptor (TLR)	Inflammation/Immunology
Lipopolysaccharides, from S. enterica serotype typhimurium, are a kind of lipid-polysaccharide endotoxin. Smooth Gram-negative bacteria's lipopolysaccharides are made up of three components: lipid A, core oligosaccharide, and O antigen (OAg). The O antigen is a polymer of sugar repeat units (RUs); the Wzz protein regulates the length of the O antigen in lipopolysaccharides, and the number of RUs attached to lipid A is determined by the modal value set by the Wzz protein. S. enterica typhimurium has two Wzz proteins: Wzz_ST (which makes the modal range of the O antigen between 16 and 35 RUs) and Wzz_fepE (which makes the modal value over 100 RUs). Mutating the genes corresponding to these two proteins causes the formation of short-chain O antigen chains and significantly reduces bacterial pathogenicity .

Antibacterial Compound Library	1,481 compounds
Antibacterial agents are a group of materials that fight against pathogenic bacteria. Thus, by killing or reducing the metabolic activity of bacteria, their pathogenic effect in the biological environments will be minimized. The most widely used antibacterial agents exert their effects on bacterial cell wall synthesis, protein synthesis, DNA replication and metabolic pathways. However, resistance to antimicrobial agents has become a major source of morbidity and mortality worldwide. The main mechanisms of resistance are limiting uptake of a drug, modification of a drug target, inactivation of a drug, and active efflux of a drug. Therefore, it is an urgent need to develop new drugs targeted at resistant organisms. MCE offers a unique collection of 1,481 compounds with validated antibacterial activities. MCE antibacterial compound library is an effective tool for drug repurposing screening, combination screening and biological investigation.
