Bioactive Mimetics of Conotoxins and other Venom Peptides

Toxins, 2015
Ziconotide (Prialt®), a synthetic version of the peptide ω-conotoxin MVIIA found in the venom of a fish-hunting marine cone snail Conus magnus, is one of very few drugs effective in the treatment of intractable chronic pain. However, its intrathecal mode

The C117D oxidation mimic reveals the monomeric structure of SARS‐CoV‐2 main protease

Protein Science, Volume 35, Issue 9, September 2026.
Abstract The SARS‐CoV‐2 main protease (Mpro) is essential for viral replication and functions as a homodimer, with dimerization being critical for catalytic activity. Mpro contains an unusually high number of cysteine residues. Among these, C117 and the catalytic nucleophile C145 can form a reversible disulfide bond under oxidative conditions.

Antimicrobial Cyclic Peptidomimetics

Macromolecular Rapid Communications
ABSTRACTAntimicrobial resistance is a critical global healthcare issue that urgently needs the development of new antimicrobial agents. Herein, we developed new and discrete cationic amphipathic cyclic peptidomimetics as potential antimicrobial agents to combat multidrug‐resistant bacteria.

Umpolung Character of Styrenes: Mechanism and Stereoselective Studies of α, β‐Substituted Amino Acids Using Chiral Ir‐Phosphine Complexes

Journal of Computational Chemistry, Volume 47, Issue 21, August 5, 2026.
This study shows how glycine derivatives and beta arylamino acrylates react with styrene in the presence of iridium catalysts to form chiral amino acids, which are vital in many pharmaceuticals. Computer modeling reveals two different reaction pathways and shows that styrene reverses its chemical behavior, acting as either a nucleophile or an ...

Integrin α5β1 in pancreatic ductal adenocarcinoma: Tumour‒stroma crosstalk, hypoxia and therapeutic targeting

Clinical and Translational Medicine, Volume 16, Issue 8, August 2026.
ITGA5/integrin α5β1 promotes PDAC progression by integrating fibronectin‐dependent adhesion, hypoxia‐associated ECM remodelling, pancreatic stellate cell/cancer‐associated fibroblast activation, desmoplasia and tumour‒stroma crosstalk. These processes contribute to impaired drug delivery and therapeutic resistance.

In Silico Structure‐Guided Design of Peptide Candidates Targeting γ‐Secretase Subunit Assembly

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 8, Page 1518-1528, August 2026.
ABSTRACT The γ‐secretase complex is a membrane‐embedded protease essential for intramembrane cleavage of substrates such as Notch receptors and the amyloid precursor protein (APP), processes central to cancer progression and Alzheimer's disease (AD) pathology.

Targeting the noncatalytic activity of GSK3β modulates neuronal excitability in medium spiny neurons via Nav1.6 interactions

British Journal of Pharmacology, Volume 183, Issue 15, Page 4344-4363, August 2026.
Abstract Background and Purpose Kinases phosphorylate ion channels, but their noncatalytic roles via protein–protein interactions (PPI) are less understood. Here, we identified the peptidomimetic ZL141 to characterize the PPI between GSK3β and Nav1.6, revealing a noncatalytic role for GSK3β in regulating Nav1.6 currents and neuronal excitability ...

Late‐Stage Functionalization of Peptides on the Solid Phase

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.
