Antimicrobial peptide that displays antibacterial, antiprotozoal, and antiviral activity (PubMed:32443921). Exhibits antibacterial activity against the Gram-positive bacteria S.epidermidis ATCC 12228 (MIC=4 uM), E.casseliflavus ATCC 700327 (MIC=4 uM), S.aureus ATCC 25923 (MIC=8 uM) and E.faecalis ATCC 29212 (MIC=8 uM), and the Gram-negative bacteria E.coli ATCC 25922 (MIC=8 uM), K.pneumoniae ATCC 13883 (MIC=8 uM), the multi-resistant clinical isolate strain K.pneumoniae carbapanemase (KPC) MR (MIC=16 uM), and P.aeruginosa ATCC 27853 (MIC=32 uM) (PubMed:32443921). Displays antiprotozoal activity against the epimastigote form of T.cruzi (IC(50)=6.32 uM) (PubMed:32443921). Does not show antimicrobial against the fungi C.albicans ATCC 90028 and C.parapsilosis ATCC 22019 (PubMed:32443921). Displays antiviral activity against the human viruses chikungunya (EC(50)=17.9 uM), Dengue serotype 4 (EC(50)=20.8 uM) and Yellow Fever (EC(50)=21.8 uM) (PubMed:32443921). Shows moderate cytolytic activity against human erythrocytes (HC(50)=48.9 uM), and activates the oxidative burst in human neutrophils (PubMed:32443921). Also displays anti-proliferative effects against MCF-7 breast cancer cells (IC(50)=15.3 uM) and B16F10 murine melanoma cells (IC(50)=12.8 uM) (PubMed:32443921). Expressed by the skin glands. Belongs to the frog skin active peptide (FSAP) family.
