FuK
FuK is a WK2-analog antimicrobial peptide modified with fluorinated unnatural amino acids. FuK has an LD50 of 72.34 mg/kg in mice, shows no hemolytic activity, with high stability against trypsin, chymotrypsin, and saline environments. FuK exerts bactericidal effects by enhancing the permeability of bacterial outer membranes, inducing depolarization of cytoplasmic membranes, and disrupting membrane potential balance against bacterias such as Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, and MRSA. FuK exhibits synergistic antimicrobial activity with polymyxin B (HY-149179), vancomycin (HY-B0671), and ciprofloxacin (HY-B0356), and also inhibits Ciprofloxacin-induced bacterial drug resistance. FuK has in vivo safety, effectively reduces bacterial load and inflammatory cell infiltration in a mouse MRSA model, and promotes collagen fiber formation in skin wounds.

Biological Activity
FuK (5-10 mg/kg; local administration; at 4, 12, and 24 hours post-infection) effectively treats MRSA-induced skin wound infections in BALB/c mice, promotes wound healing, and reduces bacterial load and inflammatory cell infiltration[1].

-
Animal Model:BALB/c (male, 6−8 weeks old, 18−20 g) challenged with nebulized K. pneumoniae suspension[1]
-
Dosage:5 mg/kg; 10 mg/kg
-
Administration:i.p.; at 4 and 12 h post-infection
-
Result:Reduced K. pneumoniae lung burden to 5.32 × 105 CFU/mg (5 mg/kg dose) and 3.71 × 105 CFU/mg (10 mg/kg dose).
Caused slight alveolar dilation and reduced inflammatory cell infiltration, with enhanced therapeutic effects at higher doses.
