AI Article Synopsis

  • * The study focused on creating Fmoc-triazine amino acids with different chemical properties for better AMP formulations, leading to the synthesis of new amphipathic peptidomimetics.
  • * The most effective compound identified was a trimer that not only exhibited strong antimicrobial activity without harming red blood cells but also showed improved stability against proteolytic degradation and targeted bacteria internally.*

Article Abstract

To combat the escalating rise of antibacterial resistance, the development of antimicrobial peptides (AMPs) with a unique mode of action is considered an attractive strategy. However, proteolytic degradation of AMPs remains the greatest challenge in their transformation into therapeutics. Herein, we synthesized Fmoc-triazine amino acids that differ from each other by anchoring either cationic or hydrophobic residues. These unnatural amino acids were adopted for solid-phase peptide synthesis (SPPS) to synthesize a series of amphipathic antimicrobial peptidomimetics. From the antimicrobial screening, we found that the trimer, is the most potent short antimicrobial peptidomimetic without showing hemolytic activity and it displayed enhanced proteolytic stability. Moreover, the mechanism of action to kill bacteria was found to be an intracellular targeting.

Aminotransferase is involved in the regulation of amino acid metabolism, which can affect the balance and distribution of amino acids in the organism, help maintain the homeostasis of amino acids in the organism, and play an important role in the environmental adaptation of aquatic animals. In this study, a total of 28 aminotransferase genes were identified in the genome of R. philippinarum.

Introduction: Adverse exposures in utero might cause adaptations of cardiovascular and metabolic organ development, predisposing individuals to an adverse cardio-metabolic risk profile from childhood onwards. We hypothesized that adaptations in metabolic pathways underlie these associations and examined associations of metabolite profiles at birth with childhood cardio-metabolic risk factors.

Methods: The study included 763 mother-child pairs participating in an ongoing population-based prospective cohort study with an overall low disease risk.

Traditional drug-delivery methods are limited by low bioavailability and nonspecific drug distribution, resulting in poor therapeutic efficacy and potential risks of toxicity. Mesoporous silica nanoparticles (MSNs) have attracted wide attention as drug-delivery carriers due to their large specific surface area, adjustable pore size, good mechanical strength, good biocompatibility, and rich hydroxyl groups on their surface. In this paper, MSNs were synthesized by a template method, and the morphology and pore structure were regulated.

Non-covalent protein-protein interactions are one of the most fundamental building blocks in cellular signalling pathways. Despite this, they have been historically hard to identify using conventional methods due to their often weak and transient nature. Using genetic code expansion and incorporation of commercially available unnatural amino acids, we have developed a highly accessible method whereby interactions between biotinylated ubiquitin-like protein (UBL) probes and their binding partners can be stabilised using ultraviolet (UV) light-induced crosslinks.
