Development of the force field for cyclosporine A

open access: yesBiophysics and Physicobiology, 2022
Membrane permeability of cyclic peptides is an important factor in drug design. To investigate the membrane permeability of cyclic peptides using molecular dynamics (MD) simulations, the accurate force fields for unnatural amino acids present in the ...

Trypsin inhibition by macrocyclic and open-chain variants of the squash inhibitor MCoTI-II [PDF]

open access: yes, 2005
MCoTl-I and MCoTl-II from the seeds of Momordica cochinchinensis are inhibitors of trypsin-like proteases and the only known members of the large family of squash inhibitors that are cyclic and contain an additional loop connecting the amino- and the ...

Antimicrobial Cyclic Peptides for Plant Disease Control

open access: yesThe Plant Pathology Journal, 2015
Antimicrobial cyclic peptides derived from microbes bind stably with target sites, have a tolerance to hydrolysis by proteases, and a favorable degradability under field conditions, which make them an attractive proposition for use as agricultural ...

Simultaneous cyclization and derivatization of peptides using cyclopentenediones [PDF]

open access: yes, 2017
Unprotected linear peptides containing N-terminal cysteines and another cysteine residue can be simultaneously cyclized and derivatized using 2,2-disubstituted cyclopentenediones. High yields of cyclic peptide conjugates may be obtained in short reaction

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.

Immobilization by surface conjugation of cyclic peptides for effective mimicry of the HCV-envelope E2 protein as a strategy toward synthetic vaccines [PDF]

open access: yes, 2018
Mimicry of the binding interface of antibody-antigen interactions using peptide-based modulators (i.e. epitope mimics) has promising applications for vaccine design.

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).
