Metabolite Identification
Common NameD-histidine
DescriptionD-histidine is a non-proteinogenic amino acid belonging to the class of metabolites. Its chemical structure features a chiral center, distinguishing it from L-histidine, with implications for its biological activity. Recent studies have highlighted D-histidine's role in combating biofilm formation, particularly against pathogens such as Aggregatibacter actinomycetemcomitans and Pseudomonas aeruginosa (PMID:41020610 ). D-histidine has been shown to inhibit biofilm formation and disrupt established biofilms in a concentration-dependent manner, without adversely affecting bacterial growth (PMID:41020610 ). Additionally, it downregulates the expression of virulence factors by inhibiting quorum sensing-related genes (PMID:41020610 ). Notably, when combined with antibiotics like amoxicillin, minocycline, and metronidazole, D-histidine enhances biofilm eradication, allowing for lower dosages of these antibiotics (PMID:41020610 ). This synergistic effect positions D-histidine as a promising adjunctive therapeutic agent, addressing the growing challenge of antibiotic resistance and biofilm-associated antibiotic tolerance in periodontal treatments (PMID:41020610 ).
