Infection is a pathophysiological process that involves the invasion and colonization of a living organism (host) by disease-causing infectious agents, the reaction of host tissues to these agents and the toxins they produce, and the transmission of infectious agents to other hosts. Common infectious agents include viruses, viroids, prions, bacteria, nematodes, arthropods, and other macroparasites such as tapeworms. Hosts can fight infections using their immune system. Mammals often engage both innate and adaptive immune systems to eliminate infectious agents or inhibit their growth and transmission. When infection occurs, anti-infective drugs can suppress the infection. Several broad types of anti-infective drugs exist, depending on the type of organism targeted; they include antibacterial (antibiotic), antiviral, antifungal and antiparasitic agents.

    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 (Cu2+).
