piscidin-1

Piscidin-1 (22-42) is a highly potent, multifunctional Antimicrobial Peptide (AMP) produced by the Orange-spotted grouper (Epinephelus coioides).

Piscidin-1 (22-42) (TFA) is a highly potent, multi-functional Antimicrobial Peptide (AMP) produced by Orange-spotted grouper (Epinephelus coioides).

TP4 (Nile tilapia piscidin) is an orally active, piscidin-like antimicrobial peptide that inhibits various gram-positive and gram-negative bacterial strains with a minimum inhibitory concentration (MIC) ranging from 0.03 to 10 μg mL. It demonstrates hemolytic activity and promotes immune response, antioxidant activity, and intestinal health in the presence of bacterial infections. Additionally, TP4 has an anti-tumor effect and induces necrosis in cancer cells by triggering mitochondrial dysfunction [1] [2] [3].

Tilapia piscidin 3, an antimicrobial peptide, exhibits antibacterial properties effective against both gram-positive and gram-negative bacteria. It has demonstrated minimum inhibitory concentrations (MICs) of 2.44 µg/mL for V. vulnificus 204 and V. alginolyticus, 9.78 µg/mL for S. agalactiae 819, 19.55 µg/mL for E. faecalis BCRC 10066, and 0.61 µg/mL for S. agalactiae BCRC 10787. Additionally, it presents hemolytic activity on fish red blood cells [1].
