Iseganan is an anti-microbial peptide that is active against both Gram-positive and Gram-negative bacteria and fungi. Iseganan kills a broad-spectrum of bacteria and fungi by attaching to and destroying the integrity of the lipid cell membranes. Iseganan can be used for oral mucositis research.

Defensin HNP-1 human TFA is a type of human neutrophil peptide (HNPs). Defensin HNP-1 human TFA possesses immunomodulatory functions and can delay the apoptosis of neutrophils. Defensin HNP-1 human TFA inhibits DNA/RNA/protein synthesis and interferes with metabolic pathways, thus exhibiting broad antibacterial activity. Defensin HNP-1 human TFA has direct inactivation effects on HIV, HSV-1, HSV-2, CMV, influenza virus, etc. Defensin HNP-1 human TFA has antileishmanial activity. Defensin HNP-1 human TFA is involved in endothelial cell dysfunction during the early development of atherosclerosis.

LAH4 TFA, an alpha-helix of the designed amphipathic peptide antibiotic, exhibits potent antimicrobial, nucleic acid transfection and cell penetration activities. LAH4 TFA possesses high plasmid DNA delivery capacities. LAH4 TFA has a strong affinity for anionic lipids found in the outer membrane of bacterial membranes.

Omiganan, FITC labeled is a peptide-FITC complex composed of Omiganan and a FITC. Omiganan is a bactericidal and fungicidal cationic peptide being developed as a topical gel for prevention of catheter-associated infections. FITC is a derivative of fluorescein for the labeling of amines.

Peceleganan (PL-5) acetate is an artificial antimicrobial cecropin A (1-10) × melittin B (3-18) hybrid (10+16)-peptide analogue. Peceleganan acetate inhibits wound infection.

Alloferon 1 is an antiviral and antitumoral peptide. Alloferon 1 stimulates natural cytotoxicity of human peripheral blood lymphocytes. Alloferon 1 also induces IFN synthesis, and enhances antiviral and antitumor resistance in mice. Alloferon 1 also shows anti-inflammatory activity in λ-carrageenan-induced paw edema model. Alloferon 1 can be isolated from the blood of the blow fly Calliphora vicina (Diptera).

SMAP‑29 is a cathelicidin antimicrobial peptide with LPS‑binding and anti‑inflammatory properties. SMAP‑29 exerts broad‑spectrum antimicrobial activity against bacteria, fungi and multidrug‑resistant isolates. SMAP‑29 kills pathogens by permeabilizing bacterial membranes, inducing depolarization and cell lysis, and also inhibits inflammatory cytokines while reducing lethality in septic shock and pneumonia models. SMAP-29 can be used for research on bacterial infections, drug-resistant infections, septic shock.

Lactoferricin B (4-14), bovine (TFA), a peptide corresponding to residues 4-14 of bovine lactoferrin, has antimicrobial activity against a wide range of microorganisms.

Lactoferrin 17-41 (Lactoferricin B), a peptide corresponding to residues 17-41 of bovine lactoferrin, has antimicrobial activity against a wide range of microorganisms, including Gram-positive and Gramnegative bacteria, viruses, protozoa, and fungi. Lactoferrin 17-41 has antitumor activities.

Dermaseptin, a peptide isolated from frog skin, exhibits potent antimicrobial activity against bacteria, fungi, and protozoa at micromolar concentration.

Salivaricin B is a broad-spectrum bacteriocin produced by Lactobacillus M7. Salivaricin B reduces cell wall thickness, induces abnormal septum formation, and exerts rapid bactericidal activity against susceptible Gram-positive bacteria without disrupting cytoplasmic membrane integrity or dissipating membrane potential. Salivaricin B inhibits the growth of oral, upper respiratory tract and food-related Gram-positive pathogens, spoilage bacteria, lactobacilli, and SboB-non-producing Streptococcus salivarius strains. Its activity is strain-dependent, and it has no effect on Gram-negative bacteria. Salivaricin B can be used in studies related to bacterial infections.

Bac7(1-35) acetate is a proline-rich antimicrobial peptide. Bac7(1-35) acetate efficiently binds to different regions of prokaryote ribosomes, leading to the inhibition of protein synthesis. Bac7(1-35) acetate demonstrates in vitro activity against P. aeruginosa strains.
