Oral Delivery Systems for Food‐Derived Bioactive Peptides: Enhancing Stability, Bioavailability, and Health Benefits

Advanced Science, EarlyView.
Advanced delivery systems—including nanoparticles, nanoemulsions, liposomes, and hydrogels—protect food‐derived bioactive peptides from gastrointestinal degradation and bitterness. These systems enable pH‐responsive release, enhance intestinal absorption, and improve therapeutic efficacy against oxidative stress, metabolic disorders, cancer, and ...

Effects of Lactobacillus helveticus Fermentation on the Ca2+ Release and Antioxidative Properties of Sheep Bone Hydrolysate

Food Science of Animal Resources, 2018
Both the calcium and collagen in bone powder are hard to be absorbed by the body. Although enzymatic hydrolysis by protease increased the bio-availability of bone powder, it was a meaningful try to further increase Ca2+ release, oligopeptide formation ...

The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

Advanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

Substrate‐Selective Inhibition of the SARS‐CoV‐2 Papain‐Like Protease: Inhibition of Hydrolysis of Human Over Viral Substrates

Chemistry – A European Journal, EarlyView.
The SARS‐CoV‐2 papain‐like protease (PLpro) is a medicinal chemistry target. Here we report mass spectrometry assays employing oligopeptide substrates based on the sequences of the viral polyproteins 1a/1ab and on an ISG15‐modified human protein, which enabled the identification of substrate‐selective PLpro inhibitors.

Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

Chemistry – A European Journal, EarlyView.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Nano MIPs (Molecularly Imprinted Polymers) Prepared From a “Frustrated” Gold Nanoparticle‐Based Pre‐Imprinting Matrix: Enhancing Binding Affinity and Selectivity

Chemistry – A European Journal, EarlyView.
A comparative study across ligand‐stabilized gold nanoparticles and surfactant micelles reveals that molecular imprinting strongly depends on the nanoplatform used for imprinting. “Frustrated” noncovalent interactions within the monolayer on gold nanoparticle surface can be exploited to improve both the binding affinity and selectivity for ...

Proteomic profiling of Elp1‐deficient trigeminal ganglia reveals disruption of neurotrophic and metabolic pathways in a familial dysautonomia mouse model

Developmental Dynamics, EarlyView.
Abstract Background Elp1, a subunit of the Elongator complex, is essential for tRNA modification and neuronal development. Mutations in ELP1 underlie familial dysautonomia (FD), a disorder marked by sensory and autonomic neuropathy. While loss of Elp1 disrupts trigeminal ganglion formation and survival, the downstream molecular consequences remain ...

Peptide Uptake Is Essential for Borrelia burgdorferi Viability and Involves Structural and Regulatory Complexity of its Oligopeptide Transporter

mBio, 2017
Borrelia burgdorferi is an extreme amino acid (AA) auxotroph whose genome encodes few free AA transporters and an elaborate oligopeptide transport system (B. burgdorferi Opp [BbOpp]).
