The role of oligopeptides in preventing autism
Medical Hypotheses, 2020Previous reports in this series point to insufficient insulin-like growth factor-1 (IGF1) in the newborn as the key to brain dysconnectivity characteristic of autism. Such a deficiency should be detectable in the baby's blood at or soon after birth. Breast-feeding exclusively for the first year of postpartum life or supplementation with oral agents to ...

Russian Chemical Bulletin, 2019
The paper presents the results concerning the use of the supercomputer docking program SOL-P, which performs a search for low-energy minima of protein—ligand complexes in the MMFF94 force field without using a grid of precalculated potentials for protein—ligand interactions. The SOL-P docking program can be applied to the generalized docking of ligands

Molecular Radical Cations of Oligopeptides
The Journal of Physical Chemistry B, 2000An unprecedented method of producing molecular radical cations of oligopeptides in the gas phase has been discovered. Electrospraying a methanolic mixture of a Cu(II)−amine complex, e.g., CuII(dien)(NO3)2 (where dien = diethylenetriamine), and an oligopeptide (M) yields the [CuII(dien)M]•2+ ion, whose collision-induced dissociation (CID) produces [CuI ...

SYNTHESIS and PROPERTIES OF ARGININE OLIGOPEPTIDES
International Journal of Protein Research, 1970Di‐, tri‐, and tetra‐arginine were prepared from carbobenzoxy‐nitro‐L‐arginine via carbobenzoxy‐nitro‐L‐arginyl‐nitro‐L‐arginine methyl ester, carbobenzoxy‐nitro‐L‐arginyl‐nitro‐L‐arginyl‐nitro‐L‐arginine methyl ester, and carbobenzoxy‐nitro‐L‐argi‐nyl‐nitro‐L‐arginyl‐nitro‐L‐arginyl‐nitro‐L‐arginine methyl ester, respectively, by mixed anhydride and ...

Oligopeptide cyclophilin inhibitors: A reassessment
European Journal of Medicinal Chemistry, 2011Potent cyclophilin A (CypA) inhibitors such as non-immunosuppressive cyclosporin A (CsA) derivatives have been already used in clinical trials in patients with viral infections. CypA is a peptidyl prolyl cis/trans isomerase (PPIase) that catalyzes slow prolyl bond cis/trans interconversions of the backbone of substrate peptides and proteins.

Thermolysin: Kinetic Study with Oligopeptides
European Journal of Biochemistry, 1970Thermolysin is a well‐known protease which exhibits its specificity against hydrophobic amino acid residues such as l‐leucine, l‐phenylalanine, etc. whose amino groups donate the susceptible peptide bonds (amino‐endopeptidase). The present study was undertaken to investigate the effects of neighboring residues surrounding the sensitive amino acid ...

Intestinal Absorption of Oligopeptides in Cystinuria
Clinical Science, 19711. The intestinal transport of oligopeptides containing either lysine or arginine has been compared with that of the corresponding free amino acids in six homozygous cystinuric patients and in six normal adult subjects by use of the oral tolerance test technique. 2.

Self-Assembly of Homo Phenylalanine Oligopeptides: Role of Oligopeptide Chain Length
LangmuirThe self-assembly of phenylalanine (F)-based peptides is a critical area of research with potential implications for the development of advanced biomaterials and technologies. Previous studies indicate that homo-oligopeptides with F-X residues (X = 1 to 6) can self-assemble into diverse nano-microstructures, but the role of oligopeptide chain length on

Metal ion selectivity of oligopeptides
Dalton Trans., 2006Metal binding affinity and selectivity of peptides are reviewed with a special emphasis on the high structural variety of peptide complexes. The most common structural type of these complexes is built up by the deprotonation and metal ion coordination of subsequent amide groups in the form of fused five-membered chelate rings. The metal ion selectivity
