Orthogonal protection of peptides and peptoids for cyclization by the thiol-ene reaction and conjugation [PDF]

open access: yes, 2014
Cyclic peptides and peptoids were prepared using the thiol-ene Michael-type reaction. The linear precursors were provided with additional functional groups allowing for subsequent conjugation: an orthogonally protected thiol, a protected maleimide, or an

The multicomponent approach to N-methyl peptides: total synthesis of antibacterial (–)-viridic acid and analogues

open access: yesBeilstein Journal of Organic Chemistry, 2012
Two syntheses of natural viridic acid, an unusual triply N-methylated peptide with two anthranilate units, are presented. The first one is based on peptide-coupling strategies and affords the optically active natural product in 20% overall yield over six

Characterization of Novel Antimicrobial Peptoids [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 1999
ABSTRACT Peptoids differ from peptides in that peptoids are composed of N-substituted rather than alpha-carbon-substituted glycine units. In this paper we report the in vitro and in vivo antibacterial activities of several antibacterial peptoids discovered by screening combinatorial chemistry libraries for bacterial growth ...

Real‐Time Monitoring of Multitarget Antimicrobial Mechanisms of Peptoids Using Label‐Free Imaging with Optical Diffraction Tomography

open access: yesAdvanced Science, 2023
Antimicrobial peptides (AMPs) are promising therapeutics in the fight against multidrug‐resistant bacteria. As a mimic of AMPs, peptoids with N‐substituted glycine backbone have been utilized for antimicrobials with resistance against proteolytic ...

Highly stable and tunable peptoid/hemin enzymatic mimetics with natural peroxidase-like activities

open access: yesNature Communications, 2022
Peroxidase mimics are currently being investigated as catalysts for lignin depolymerisation. In this article, the authors investigate a class of self-assembled and highly stable peptoid/hemin nanomaterials as peroxidase mimics that are highly stable and ...

Antimicrobial activity, mechanism of action, and methods for stabilisation of defensins as new therapeutic agents

open access: yesBiotechnology & Biotechnological Equipment, 2019
Bioactive compounds, such as antimicrobial peptides (AMPs), have increasingly been used recently to counteract the rapidly increasing incidence of bacterial resistance to usual antibiotics and chemotherapeutics. In humans, endogenous AMPs are part of the

Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth

open access: yesAdvanced Functional Materials, Volume 36, Issue 34, 27 April 2026.
Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.

Engineering Lipid Nanoparticles for Precision RNA Delivery: Design Principles, Targeting Strategies, and Clinical Prospects

open access: yesCancer Nexus, Volume 2, Issue 2, April 2026.
ABSTRACT Lipid nanoparticles (LNPs) represent the most clinically advanced platform for RNA delivery and have enabled major breakthroughs in vaccines and gene therapies. However, their broader application is still limited by inefficient extrahepatic delivery, immunogenicity, and insufficient control over tissue‐ and cell‐specific targeting. This review
