Cat. No.: HY-P1068
CAS No.: 9001-63-2
Synonyms: Muramidase
Lysozyme (Muramidase) is a conserved antimicrobial protein. Lysozyme exerts its bactericidal effect by hydrolyzing bacterial cell wall peptidoglycan (PG). Lysozyme plays an important role in limiting bacterial growth on mucosal surfaces and other sites, not only controlling potential pathogens but also limiting overgrowth of microbiota to prevent dysbiosis. Extracellular lysozyme can also degrade polymeric PG into soluble fragments, activate NOD receptors in mucosal epithelial cells, and lead to the secretion of chemokines and activating factors by neutrophils and macrophages .

Tryptone is a peptide-rich bacterial culture medium component that can regulate bacterial cell surface proteins and biofilm-related genes. Tryptone promotes the expression and assembly of bacterial adhesion proteins (such as LapA and LapF) by providing peptide substances as structural factors, enhancing cell surface hydrophobicity and intercellular adhesion, thereby stabilizing the biofilm matrix and supporting the maturation and maintenance of bacterial biofilms. The peptide mixture contained in Tryptone can specifically regulate the transcription of bacterial adhesion-related genes (such as activating LapA and inhibiting LapF), affecting the synthesis and localization of biofilm structural proteins .

Synonyms: SPA
Protein A (SPA) is an immunoglobulin (Ig)-binding protein that exists on the bacterial surface and can be freely secreted into the extracellular environment. Protein A blocks opsonophagocytosis and induces B cell apoptosis in vitro by binding to the Fc region of antibodies and the Fab region of B cell receptors. Protein A can form toxic immune complexes with IgG, thereby inducing leukocyte necrosis. Protein A contributes to the virulence expression of Staphylococcus aureus. Protein A triggers allergic reactions in IgG-pretreated mouse models. Protein A can be used in studies related to immune system diseases .

Infection

Polyquaternium-1 (Polidronium chloride; PQ-1) is an antimicrobial preservative and an activator of NF-κB. Polyquaternium-1 targets bacterial cell membranes, commonly used in ophthalmic surgery. Polyquaternium-1 adsorbs to the surface of microbial membranes through its polycationic properties, destroying membrane integrity and inducing potassium ion leakage, leading to bacterial death. Polyquaternium-1 exerts antimicrobial effects at a concentration of 0.001% and has low toxicity to mammalian cells. Polyquaternium-1 can be used to prepare products such as glaucoma eye drops (Travoprost preparations containing PQ-1), artificial tears, and contact lens solutions to reduce the ocular surface toxicity of traditional preservatives such as benzalkonium chloride (HY-B2232) .

Synonyms: (±)-Massoia lactone
Massoia lactone ((±)-Massoia lactone) is a natural lactone-based biosurfactant with antifungal (fungal), antibiofilm, and cytotoxic activities. Massoia lactone inhibits fungal hyphal growth and spore germination, and induces fungal cell necrosis by forming membrane pores, reducing ergosterol, elevating ROS, and causing leakage of intracellular components. Massoia lactone inhibits the viability and proliferation of tumor cells. Massoia lactone degrades the extracellular polymeric substances of polymicrobial biofilms, penetrates the biofilm matrix, inhibits the growth of planktonic oral bacteria (bacterial), and reduces surface tension through its amphiphilic properties. Massoia lactone is a low-toxicity, biodegradable food additive with a coconut cream aroma, which can be used for flavor improvement and also serves as a quality control marker for Cs-4 mycelium. Massoia lactone can be used for research on Fusarium head blight, malignant tumors, and oral polymicrobial biofilm-associated dental diseases .
