HY-W015450

D-Ala-D-Ala D-Alanyl-D-alanine; H-D-Ala-D-Ala-OH	Endogenous Metabolite	Others
D-Ala-D-Ala is a bacterial endogenous metabolite. D-Ala-D-Ala constitutes the terminus of the peptide part of the peptidoglycan monomer unit and is involved in the transpeptidation reaction as the substrate. D-Ala-D-Ala is catalyzed by D-Alanine-D-Alanine ligase .

HY-131150

Ristomycin sulfate	Antibiotic Bacterial	Cardiovascular Disease Infection
Ristomycin sulfate is an antibacterial antibiotic and platelet aggregation inducer. Ristomycin sulfate interacts with the D-alanyl-D-alanine terminus of bacterial cell wall precursors to regulate bacterial cell wall synthesis. Ristomycin sulfate induces platelet aggregation in vitro and inhibits the growth of Gram-positive bacteria. Ristomycin sulfate serves as an in vitro diagnostic compound for detecting von Willebrand factor activity. Ristomycin sulfate is applicable to research related to von Willebrand disease and Bernard-Soulier syndrome .

HY-107833

A40926	Antibiotic Bacterial	Infection
A40926 is a glycopeptide antibiotic that targets the bacterial cell wall peptidoglycan precursor *D-alanyl-D-alanine* (D-Ala-D-Ala). A40926 irreversibly inhibits cell wall synthesis by competitively binding to this target, and has high bactericidal activity against Gram-positive bacteria (such as Staphylococcus, Streptococcus) and Neisseria gonorrhoeae, with MIC=0.06-2 μg/mL, and is also effective against penicillin-resistant strains. A40926 blocks peptidoglycan cross-linking, destroys cell wall integrity, and causes bacterial lysis and death. A40926 has a fat-soluble fatty acid structure, which can increase serum concentrations and prolong the duration of action (e.g., the terminal half-life in rats is 61.22 h) .
