Antibiotic resistance is a global health crisis increasing in prevalence every day. To combat this crisis, alternative antimicrobial therapeutics are urgently needed. Antimicrobial peptides (AMPs), family of short defense proteins, produced naturally by all organisms and hold great potential as effective alternatives to small molecule antibiotics. Here, we present rAMPage, scalable bioinformatics discovery platform for identifying AMP sequences from RNA sequencing (RNA-seq) datasets. In our study, demonstrate the utility scalability running it on 84 publicly available RNA-seq datasets 75 amphibian insect species-species known have rich repertoires. Across these datasets, identified 1137 putative AMPs, 1024 which were deemed novel homology search cataloged AMPs public databases. We selected 21 peptide set susceptibility testing against Escherichia coli Staphylococcus aureus observed that seven them high activity. Our study illustrates how silico methods such rAMPage can enable fast efficient an first step strenuous process drug development.

Antimicrobial resistance has become a critical global health problem due to the abuse of conventional antibiotics and rise multi-drug-resistant microbes. peptides (AMPs) are group natural that show promise as next-generation their low toxicity host, broad spectrum biological activity, including antibacterial, antifungal, antiviral, anti-parasitic activities, great therapeutic potential, such anticancer, anti-inflammatory, etc. Most importantly, AMPs kill bacteria by damaging cell membranes using multiple mechanisms action rather than targeting single molecule or pathway, making it difficult for bacterial drug develop. However, experimental approaches used discover design new very expensive time-consuming. In recent years, there been considerable interest in silico methods, traditional machine learning (ML) deep (DL) approaches, discovery. While few papers summarizing computational AMP prediction none them focused on DL methods. this review, we aim survey latest methods achieved approaches. First, biology background is introduced, then various feature encoding represent features peptide sequences presented. We explain most popular techniques highlight works based classify novel sequences. Finally, discuss limitations challenges prediction.

Antimicrobial peptides (AMPs) are short, mainly positively charged, amphipathic molecules. AMPs important effectors of the immune response in insects with a broad spectrum antibacterial, antifungal, and antiparasitic activity. In addition to these well-known roles, exhibit many other, often unobvious, functions host. They support elimination viral infections. participate regulation brain-controlled processes, e.g., sleep non-associative learning. By influencing neuronal health, communication, activity, they can affect functioning insect nervous system.

Antibiotic resistance represents a global health threat, challenging the efficacy of traditional antimicrobial agents and necessitating innovative approaches to combat infectious diseases. Among these alternatives, peptides have emerged as promising candidates against resistant pathogens. Unlike antibiotics with only one target, can use different mechanisms destroy bacteria, low toxicity mammalian cells compared many conventional antibiotics. Antimicrobial (AMPs) encouraging antibacterial properties are currently employed in clinical treatment pathogen infection, cancer, wound healing, cosmetics, or biotechnology. This review summarizes discusses drug resistance, limitations challenges AMPs peptide applications for combating drug-resistant bacterial infections, strategies enhance their capabilities.

Natural antimicrobial peptides (AMPs) are promising candidates for the development of a new generation antimicrobials to combat antibiotic-resistant pathogens. They have found extensive applications in fields medicine, food, and agriculture. However, efficiently screening AMPs from natural sources poses several challenges, including low efficiency high antibiotic resistance. This review focuses on action mechanisms AMPs, both through membrane non-membrane routes. We thoroughly examine various highly efficient AMP methods, whole-bacterial adsorption binding, cell chromatography (CMC), phospholipid membrane-mediated capillary electrophoresis (CE), colorimetric assays, thin layer (TLC), fluorescence-based screening, genetic sequencing-based analysis, computational mining databases, virtual methods. Additionally, we discuss potential developmental enhancing discovery. provides comprehensive framework identifying within complex product systems.

Artificial intelligence holds great promise for the design of antimicrobial peptides (AMPs); however, current models face limitations in generating AMPs with sufficient novelty and diversity, they are rarely applied to generation antifungal peptides. Here, we develop an alternative pipeline grounded a diffusion model molecular dynamics de novo AMPs. The generated by our have lower similarity identity than those other reported methodologies. Among 40 synthesized experimental validation, 25 exhibit either antibacterial or activity. AMP-29 shows selective activity against Candida glabrata vivo efficacy murine skin infection model.

Antimicrobial peptides (AMPs) have recently gained attention as a viable solution for combatting antibiotic resistance due to their numerous advantages, including broad-spectrum activity, low propensity inducing resistance, and cytotoxicity. Unfortunately, clinical application is limited short half-life susceptibility proteolytic cleavage by serum proteases. Indeed, several chemical strategies, such peptide cyclization, N-methylation, PEGylation, glycosylation, lipidation, are widely used overcoming these issues. This review describes how lipidation glycosylation commonly increase AMPs’ efficacy engineer novel AMP-based delivery systems. The of AMPs, which involves the conjugation sugar moieties glucose N-acetyl galactosamine, modulates pharmacokinetic pharmacodynamic properties, improves antimicrobial reduces interaction with mammalian cells, thereby increasing selectivity toward bacterial membranes. In same way, covalent addition fatty acids, has significant impact on therapeutic index influencing physicochemical properties highlights possibility using strategies activity conventional AMPs.
