Synthesis of potential antimicrobial peptide mimetics, peptoids [PDF]

open access: yes, 2019
During the last 10years, natural macrocyclic peptides have been tested as antimicrobial drugs against E.Coli, ect, with positive results. Because peptides are naturally occurring, infectious diseases are prone to become resistant to them the same way ...

Nitroxide‐Mediated Fluorescence Quenching: Synthesis and Applications for the Detection of ROS in Biological Systems

open access: yesAdvanced Sensor Research, Volume 5, Issue 3, March 2026.
ABSTRACT Profluorescent nitroxides (PFNs) have established themselves as powerful tools for monitoring oxidative processes and subcellular redox dynamics by reactive oxygen species (ROS). Their characteristic “off–on” behavior arises from the efficient, proximity‐driven quenching of covalently bound fluorophores by paramagnetic nitroxide radicals ...

DNA-Encoded Combinatorial Library of Macrocyclic Peptoids [PDF]

open access: yes, 2019
We report the design and synthesis of a DNA-encoded one-bead one-compound library of cyclic peptoids composed of more than 11 million molecules. We show that affinity-based screening of this large library can identify cyclic peptoid ligands for a target ...

Synthesis of Novel Steroid-Peptoid Hybrid Macrocycles by Multiple Multicomponent Macrocyclizations Including Bifunctional Building Blocks (MiBs)

open access: yesMolecules, 2007
Two new groups of cholane-peptoid hybrid macrocycles were produced by implementing novel combinations of the MiB methodology. Steroid-based hybrid macrolactams including heterocycle and aryl moieties were obtained by utilizing cholanic dicarboxylic acids

Protein Language Model‐Guided Engineering of a 2,3‐Butanediol Dehydrogenase for the Enantioselective Synthesis of Cyclic α‐Hydroxy Ketones

open access: yesAdvanced Science, Volume 13, Issue 18, 27 March 2026.
A (2R,3R)‐butanediol dehydrogenase from Bacillus subtilis (BsBDH) is engineered for the enantioselective synthesis of 2‐hydroxycyclohexanone. A PASS computational design strategy is proposed to enhance the thermostability of BsBDH. Moreover, ESM‐1v combined with ISM is utilized for enhancing and inverting its stereoselectivity.

N-[2-(Cyclohexylamino)-2-oxoethyl]-N-(4-octyloxy)phenyl-prop-2-enamide

open access: yesMolbank, 2016
N-[2-(Cyclohexylamino)-2-oxoethyl]-N-(4-octyloxy)phenyl-prop-2-enamide was prepared in good yield by coupling of 4(octyloxy)aniline, Cyclohexyl isocyanide, paraformaldehyde and acrylic acid by multicomponent Ugi reaction, at room temperature.

Protein Structure Determination by Racemic and Quasi‐Racemic X‐Ray Crystallography

open access: yesChemBioChem, Volume 27, Issue 4, 25 February 2026.
Racemic mixtures of protein enantiomers facilitate formation of diffraction‐quality crystals in centrosymmetric space groups that have quantized phases which simplify structure solution. Quasi‐racemic mixtures of a protein and its mirror image isomorph similarly facilitate formation of highly ordered crystals.
