Cat. No.: HY-W012572R
CAS No.: 351-50-8
D-Histidine (Standard) is the analytical standard of D-Histidine (HY-W012572). This product is intended for research and analytical applications. D-Histidine is an anti-biofilm agent that targets bacterial quorum sensing systems (such as RhlI/RhlR pathway) and has antibacterial activity. D-Histidine works by non-covalently binding to bacterial regulatory factors or copper ion complexes, selectively inhibiting bacterial biofilm formation and motility. D-Histidine downregulates quorum sensing-related gene expression, reduces the synthesis of virulence factors (such as alginate and proteases), and interferes with bacterial membrane stability, inhibiting biofilm formation, promoting the disintegration of mature biofilms, and enhancing antibiotic sensitivity. D-Histidine is also an efficient catalyst for the salt-induced peptide formation (SIPF) reaction, which promotes the condensation of amino acids to form dipeptides (such as dialanine and dilysine) by forming a complex with copper ions (Cu 2+) .

Synonyms: Desferrioxamine E; Nocardamin
Nocardamine (Desferrioxamine E; Nocardamin) is a cyclic trihydroxamate siderophore with iron ion chelation, antioxidant, antibacterial and other activities. Nocardamine is synthesized by Pseudomonas stutzeri under iron-deficient conditions, and excessive iron ions significantly inhibit its biosynthesis process. Nocardamine increases the level of phosphorylated ERK protein, promotes nuclear translocation of β-catenin, and restores the downregulated expression of SIRT1 protein. Nocardamine alleviates cellular oxidative stress, reduces ROS content, and simultaneously repairs the ability to form mineralized nodules and the expression of osteogenic markers. Nocardamine induces FoxA gene transcription and protein expression to assist Pseudomonas aeruginosa in iron ion uptake; it also selectively inhibits the proliferation of mycobacteria. Nocardamine induces spindle-shaped morphological changes in BM-N4 insect cells, and sufficient iron ions inhibit this cellular morphological change.
