Cat. No.: HY-W250308A
Synonyms: Epsilon-polylysine hydrochloride (MV 2000-5000); ε-Polylysine hydrochloride (MV 2000-5000); ε-PL hydrochloride (MV 2000-5000)
ε-Poly-L-lysine (Epsilon-polylysine; ε-Polylysine) hydrochloride (MV 2000-5000) is a polycationic antibacterial agent with broad-spectrum activity against Gram-positive bacteria, Gram-negative bacteria, fungi, yeasts and specific bacteriophages. ε-Poly-L-lysine hydrochloride (MV 2000-5000) exerts bactericidal effects through mechanisms such as disrupting microbial membranes, inducing ROS production, inhibiting metabolism and spore germination. ε-Poly-L-lysine hydrochloride (MV 2000-5000) also regulates the expression of multiple key genes including sodA, oxyR and recA. ε-Poly-L-lysine hydrochloride (MV 2000-5000) exhibits properties such as low eukaryotic cytotoxicity, thermal stability and pH stability, and supports tissue regeneration and anti-tumor applications. ε-Poly-L-lysine hydrochloride (MV 2000-5000) can be applied in research fields including bacterial and fungal infections, diabetic ulcers, and methicillin-resistant Staphylococcus aureus infections .

Cat. No.: HY-P11242
Cm-CATH2 is an antimicrobial peptide discovered from Chelonia mydas. Cm-CATH2 has a potent, broad-spectrum and rapid bactericidal ability by rapidly destroying the integrity of bacterial cell membranes. It shows strong activity against Gram-positive bacteria (such as VREF, Staphylococcus aureus), Gram-negative bacteria (such as Escherichia coli, Klebsiella pneumoniae), and fungi (such as Candida albicans) with MICs ranges from 1.17 to 18.75 μg/mL. Cm-CATH2 is also effective against various aquatic pathogenic bacteria. Cm-CATH2 not only inhibits biofilm formation but can also remove the formed biofilms. Cm-CATH2 has immunomodulatory functions and chemotactic effects on immune cells, and can inhibit the production of pro-inflammatory cytokines by macrophages stimulated by LPS (HY-D1056). Cm-CATH2 prevents the activation of NF-κB by inhibiting the degradation of IκBα, and also inhibits the phosphorylation of MAPK signaling pathways (p38, JNK, ERK). Cm-CATH2 demonstrates strong anti-infective ability in mouse peritonitis models and pneumonia models .

Cat. No.: HY-Y0850U5
CAS No.: 9002-89-5
Synonyms: Polyvinyl alcohol (Mw 27000, 98-99% hydrolyzed, ~600 polymerization); Poly(Ethenol) (Mw 27000, 98-99% hydrolyzed, ~600 polymerization)
PVA (Polyvinyl alcohol) (Mw 27000, 98-99% hydrolyzed, ~600 polymerization) is a nonionic ethanol homopolymer with hydrophilicity, water solubility and biodegradability. PVA (Mw 27000, 98-99% hydrolyzed, ~600 polymerization) exhibits biocompatibility, non-toxicity and non-carcinogenicity, as well as antibacterial activity against Gram-positive bacteria, Gram-negative bacteria and fungal strains. PVA (Mw 27000, 98-99% hydrolyzed, ~600 polymerization) can serve as a solubilizer, stabilizer, mucoadhesive agent and sustained-release agent, and has a synergistic solubilizing effect on voriconazole/sulfobutyl ether β-cyclodextrin complexes. By stabilizing such complexes, PVA (Mw 27000, 98-99% hydrolyzed, ~600 polymerization) forms freeze-thaw hydrogels with high mucoadhesion, sustained drug release and ex vivo corneal permeability. When compounded with hyaluronic acid hydrogels, PVA (Mw 27000, 98-99% hydrolyzed, ~600 polymerization) supports chondrocyte growth in vitro, and also forms complexes with Cu 2+, Co 2+, Ni 2+ and Zn 2+ ions. PVA (Mw 27000, 98-99% hydrolyzed, ~600 polymerization) can be used in studies related to fungal keratitis, bacterial infections and fungal infections .
