Backbone Steric Constraints Underlie High Passive Membrane Permeability of N‐Alkyl Peptides

Angewandte Chemie International Edition, EarlyView.
Beyond amide hydrogen removal, steric constraints encoded in N/Cα‐dually substituted backbones are uncovered as a key determinant of passive membrane permeability in N‐alkyl peptides. These constraints restrict conformational freedom and sterically limit backbone hydration during membrane permeation.

Beyond Simple Mimicry: Next‐Generation Geometric Architectures and Future Paradigms in Small‐Molecule and Macrocyclic Peptidomimetics

Angewandte Chemie International Edition, EarlyView.
Peptide‐to‐Small Molecule Paradigm: Peptidomimetics have evolved from simple mimicry toward drug‐like scaffolds supported by increasing clinical successes. This Perspective highlights the geometric design principles—linear repetition, convergent fusion, and cyclization—defining the next‐generation peptidomimetic architectures capable of targeting ...

Helical Folding of Abiotic Chiral Poly(phosphodiester)s

Chemistry – A European Journal, EarlyView.
Design and structural analysis of a new class of phosphodiester foldamers are presented. These oligomers that fold into single helical architecture showed length and temperature stability dependence comparable to DNA duplexes. ABSTRACT Functions of biomolecules are intimately linked to their structures which result from the folding of a linear sequence

Antifouling Glycocalyx-Mimetic Peptoids [PDF]

Journal of the American Chemical Society, 2013
The glycocalyx of the cell is composed of highly hydrated saccharidic groups conjugated to protein and lipid cores. Although components of the glycocalyx are important in cell-cell interactions and other specific biological recognition events, a fundamental role of the glycocalyx is the inhibition of nonspecific interactions at the cell surface ...

Hydroxamic Acids as HDAC Inhibitor Drug Leads for Malaria

Medicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a global health threat, with an estimated 282 million cases and 610,000 malaria‐associated deaths reported in 2024. Most mortality is due to infection by Plasmodium falciparum parasites, with the highest burden occurring in Sub‐Saharan Africa.

Mechanism‐Informed Machine Learning Enables Discovery of Oncolytic Peptides for Cancer Immunotherapy

Advanced Science, Volume 13, Issue 44, 7 August 2026.
MISPOP integrates ensemble learning with membrane‐active physicochemical priors to identify Dermaseptin‐S9, a natural oncolytic peptide that disrupts tumor membranes, triggers immunogenic cell death, and shows strong antitumor activity. The study illustrates a mechanism‐informed route from peptide sequence data to cancer immunotherapy leads.
