Interaction of the Heparin-Binding Consensus Sequence of β-Amyloid Peptides with Heparin and Heparin-Derived Oligosaccharides
Autor: Khanh Nguyen, Dallas L. Rabenstein
Publikováno v: The Journal of Physical Chemistry B. 120:2187-2197
Alzheimer's disease (AD) is characterized by the presence of amyloid plaques in the AD brain. Comprised primarily of the 40- and 42-residue β-amyloid (Aβ) peptides, there is evidence that the heparan sulfate (HS) of heparan sulfate proteoglycans (H

Kinetics and Equilibria of Cis/Trans Isomerization of Secondary Amide Peptide Bonds in Linear and Cyclic Peptides
Autor: Khanh Nguyen, Margret Iskandar, Dallas L. Rabenstein
Publikováno v: The Journal of Physical Chemistry B. 114:3387-3392
The secondary amide peptide bonds that comprise up to one-third of the bonds of peptide or protein backbones can exist as cis and trans isomers, with the trans isomer being highly favored. However, there is little quantitative data on the kinetics an

Characterization of the thiol/disulfide chemistry of peptides corresponding to the 603-609 disulfide loop of the human immunodeficiency virus (HIV) envelope glycoprotein gp41
Autor: Juan Gu, Dallas L. Rabenstein, James Russell
Publikováno v: The Journal of Peptide Research. 51:437-443
The redox chemistry of two synthetic model peptides for the 603-609 disulfide loop found in envelope glycoprotein gp41 of the human immunodeficiency virus type 1 (HIV-1) are reported. The two peptides: N-Ac-Trp-Gly-Cys-Ser-Gly-Lys-Leu-Ile-Cys-Thr-Thr

Oligo(N-aryl glycines): A New Twist on Structured Peptoids
Autor: Glenn L. Butterfoss, Richard Bonneau, Dallas L. Rabenstein, Khanh Nguyen, Barney Yoo, Neel H. Shah, Kent Kirshenbaum
Publikováno v: Journal of the American Chemical Society. 130:16622-16632
We explore strategies to enhance conformational ordering of N-substituted glycine peptoid oligomers. Peptoids bearing bulky N-alkyl side chains have previously been studied as important examples of biomimetic "foldamer" compounds, as they exhibit a c

Determination of Residue-Specific Acid Dissociation Constants for Peptides By Band-Selective Homonuclear-Decoupled 1H NMR
Autor: Dallas L. Rabenstein, Jing Wang
Publikováno v: Analytical Chemistry. 79:6799-6803
Acid dissociation constants of side-chain acidic groups of amino acid residues in peptides can be determined by 1H NMR, provided resonances can be resolved for carbon-bonded reporter protons located near the acidic group. We report here that the incr

Characterization of the Acid/Base and Redox Chemistry of Phytochelatin Analogue Peptides
Autor: Dallas L. Rabenstein, Stephen M. Spain
Publikováno v: Analytical Chemistry. 75:3712-3719
The phytochelatins are a family of polydisperse, thiol-rich peptides that are synthesized by plants in response to exposure to heavy metals. The amino acid sequence of the phytochelatin peptides is (gamma-glutamyl-cysteinyl)n-glycine, where n typical

Convenient synthesis of human calcitonin and its methionine sulfoxide derivative
Autor: Dallas L. Rabenstein, Tiesheng Shi
Publikováno v: Bioorganic & Medicinal Chemistry Letters. 12:2237-2240
The human calcitonin peptide chain was assembled using Fmoc solid-phase peptide synthesis chemistry. The combinations of cleavage Reagent H with trans-[Pt(en)(2)Cl(2)](2+) and Reagents B, K, and R with trans-[Pt(CN)(4)Cl(2)](2-) provide convenient me
