Cat. No.: HY-N2245
CAS No.: 98619-25-1
Schisandrone, a 4-aryltetralone lignan, is isolated from the dried fruits of Schisandra sphenanthera . Schisandrone is an alpha-hemolysin (Hla) inhibitor that downregulates the transcript levels of hla, agrA and RNAIII. Hla is an integral virulence determinant in Staphylococcus aureus that determines pathogenicity. Schisandrone is a potent inhibitor against MRSA pneumonia .

Cat. No.: HY-P99551
CAS No.: 1374419-41-6
Synonyms: KBSA301; AR-301

Target:  

Antibiotic Bacterial

Research Areas:  

Infection

Tosatoxumab (AR-301; KBSA301) is a human immunoglobulin G1 monoclonal antibody that specifically neutralizes alpha-toxin (alpha-hemolysin; Hla) of S. aureus. Tosatoxumab binds to an N-terminal epitope of alpha-toxin, thereby preventing functional toxin pore oligomerisation. Tosatoxumab has the potential for passive immunotherapy in the S. aureus pneumonia as an adjunctive therapy to standard antibiotic agent. Recommend Isotope Control: Human IgG1 lambda1, Isotype Control (HY-P99992) .

H052 is a selective Staphylococcus aureus α-hemolysin (Hla) inhibitor. H052 binds to Hla monomers, disrupts the interaction with host cell membranes to block pore formation, inhibiting calcium ion influx, cytotoxicity, and inflammatory responses. H052 exhibits potency (EC50=30 nM in U937 cells) against Hla-induced calcium influx. H052 is promising for research of lung infections caused by S. aureus .

Cat. No.: HY-131920
CAS No.: 27416-86-0
Synonyms: Polyuridylic acid
Poly (U) (Polyuridylic acid) is an RNA chain that exists in a disordered extended state at room temperature and serves as a TLR7 ligand. Poly (U) produces distinguishable blocking effects when transported through α-hemolysin nanopores. Poly (U) forms a triple helix with adenosine or adenosine monophosphate, thereby significantly promoting the nucleotide bond condensation reaction between adenosine monophosphate and adenosine, while exerting minimal effects on other nucleosides. When conjugated with cationic lipids, Poly (U) specifically stimulates plasmacytoid dendritic cells to produce type I interferons .

Bacterial Elastase

Research Areas:  

Infection

PV-DPD-19 is an autoinducer-2 (AI-2) quorum sensing inhibitor. PV-DPD-19 reduces AI-2 production and inhibits the expression of multiple MSCRAMMs. In co-culture systems with Staphylococcus aureus, PV-DPD-19 decreases the production of pyocyanin and Elastase in Pseudomonas aeruginosa. PV-DPD-19 impairs the adhesion ability of Staphylococcus aureus to lung epithelial cells. PV-DPD-19 inhibits biofilm formation of Pseudomonas aeruginosa (MBIC50 = 27 μg/mL) and Staphylococcus aureus (MBIC50 = 35 μg/mL). PV-DPD-19 shows no cytotoxicity in both in vitro lung epithelial cell models and in vivo Galleria mellonella larva models .

Fluorescent Dye

Research Areas:  

Others

SGC3 is a fluorescent dye with lipophilic properties. SGC3 can be used to study synaptic vesicle recycling and "kiss-and-run" exocytosis by monitoring dye efflux through nanoscale fusion pores, and its detection mechanism relies on its own lipophilic properties. SGC3 generates fluorescence when bound to lipid membranes, and a decrease in fluorescence intensity can be detected when SGC3 leaves vesicles and exists in a free state in solution .
