Animal models indicate that host defense peptides are crucial for both prevention and clearance of infection. It appears as though many peptides initially isolated as and termed "antimicrobial peptides" have been shown to have more significant alternative functions in vivo (e.g. hepcidin [18]). Dusquetide for example is an immunomodulator that ...
Defensin mimetics, also called host defense peptide (HDP) mimetics, are completely synthetic, non-peptide, small molecule structures that mimic defensins in structure and activity. [51] Similar molecules, such as brilacidin , are being developed as antibiotics , [ 52 ] anti-inflammatories for oral mucositis , [ 53 ] [ 54 ] and antifungals ...

Defensins are integral components of the innate immune system and belong to the ancient superfamily of antimicrobial peptides (AMPs). AMPs are also known as host defense peptides (HDPs), [ 2 ] and they are thought to have diverged about 1.4 billion years ago before the evolution of prokaryotes and eukaryotes.
Brilacidin (formerly PMX-30063 [2]), an investigational new drug, is a polymer-based antibiotic currently in human clinical trials, and represents a new class of antibiotics called host defense protein mimetics, or HDP-mimetics, which are non-peptide synthetic small molecules modeled after host defense peptides (HDPs).
Antimicrobial peptides are short peptides that possess antimicrobial properties. The female reproductive tract and its tissues produce antimicrobial peptides as part of the immune response. These peptides are able to fight pathogens and at the same time allow the maintenance of the microbiota that are part of the reproductive system in women ...
The alpha defensins are a family of microbicidal and cytotoxic peptides that defend the host against bacteria and viruses. HD6 has poor antibacterial potency. [ 8 ] However, HD6 affords protection against invasion by enteric bacterial pathogens by self-assembly to form fibrils and nanonets that surround and entangle bacteria.
A number of these defence peptides are secreted from the skin of frogs and other amphibians, including the opiate-like dermorphins and deltorphins, and antimicrobial dermaseptins, temporins, bombinins, magainin, pseudin, bombesins, and maculatins. [1] [2]
