Cm-CATH2

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. 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[1].
