Length12
NameWWSP
SourceSynthetic construct
ActivityAntimicrobial, Antibacterial, Anti-Gram+, Anti-Gram-
Pathogen[Ref.28921993] Gram-positive bacteria: Staphylococcus aureus (MIC = 16 μg/mL), Enterococcus faecalis (MIC = 64 μg/mL);##Gram-negative bacteria: Escherichia coli (MIC = 256 μg/mL), Pseudomonas aeruginosa (MIC > 256 μg/mL)
Hemolytic Activity[Ref.28921993] 3.9%, 2.6%, 3.6%, 4.3%, 4.0%, 4.6%, 3.3% and 2.9% hemolysis against human red blood cells at 5, 7.5, 10, 15, 20, 25, 30 and 40 μg/ml.
Cytotoxicity[Ref.28921993] The toxicity of WWSP toward HEK293 and HeLa cells is much less than nonaarginine (R9) by use of flow cytometry and the peptide doesn't show any cytotoxicity at 2 μM.
