Anion recognition by cyclic peptides [PDF]

open access: yesChemical Communications, 2015
Cyclic peptides provide excellent scaffolds for anion recognition and improved binding affinity and selectivity has been achieved through peptide backbone rigidification and the introduction of side chains bearing anion recognition groups.

Peptide oligomers from ultra-short peptides using sortase

open access: yesBiochemistry and Biophysics Reports, 2017
Sortase A catalyzed ligation of ultra-short peptides leads to inter/intra-molecular transpeptidation to form either linear or cyclic oligomers dependent upon the peptide length.

Novel Cyclic Peptides from Lethal Amanita Mushrooms through a Genome-Guided Approach

open access: yesJournal of Fungi, 2021
Most species in the genus Amanita are ectomycorrhizal fungi comprising both edible and poisonous mushrooms. Some species produce potent cyclic peptide toxins, such as α-amanitin, which places them among the deadliest organisms known to mankind.

Cyclic RGD-containing peptides: in silico exploration against BCL-X(L) [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2023
Сyclic peptides attract attention for possible applications in cancer treatment. We examined the abili­ty of six cyclic RGD-containing peptides-based compounds to inhibit B-cell lymphoma-extra-large (Bcl-XL) (PDB ID: 3zk6) using the in silico method.

Anti-oxidative stress mechanism of cyclic dipeptide in distiller's grains of strong-flavor Baijiu [PDF]

open access: yesZhongguo niangzao
In this study, the in vitro antioxidant activity of free peptides in distiller's grains of strong-flavor (Nongxiangxing) Baijiu was determined by measuring the free radical scavenging rate of 1,1-diphenyl-2-trinitrophenylhydrazine (DPPH).
