Length17
NameMAP-1
SourceSynthetic construct
ActivityAntimicrobial, Antibacterial, Anti-Gram+, Anti-Gram-
Pathogen[Ref.28921993] Gram-positive bacteria: Staphylococcus aureus (MIC = 16 μg/mL), Enterococcus faecalis (MIC = 256 μg/mL);##Gram-negative bacteria: Escherichia coli (MIC = 16 μg/mL), Pseudomonas aeruginosa (MIC = 256 μg/mL)
Hemolytic Activity[Ref.28921993] 1.6%, 0.8%, 0.6%, 0.4%, 0.7%, 1.8%, 0.4% and 0.1% 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 MAP-1 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.
