Design and Synthesis of a Dual Linker for Solid Phase Synthesis of Oleanolic Acid Derivatives

open access: yesMolecules, 2011
A hydrophilic amino-terminated poly(ethylene glycol)-type dual linker for solid phase synthesis of oleanolic acid derivatives using trityl chloride resin was designed and synthesized for the first time. Model reactions in both liquid and solid phase were

Self-Organized Criticality in Protein Folding Simulations with AMBER Parameters [PDF]

open access: yes, 2014
AMBER (Assisted Model Building with Energy Refinement) is a force field that allows for the simulation of proteins. Basic proteins were folded by a Monte-Carlo algorithm parameterized by AMBER on MATLAB. Simulations exhibited self-organized critical (SOC)

Ugi multicomponent reaction to prepare peptide–peptoid hybrid structures with diverse chemical functionalities [PDF]

open access: yes, 2018
Monodisperse sequenced peptides and peptoids present unique nano-structures based on their self-assembled secondary and tertiary structures. However, the generation of peptide and peptoid hybrid oligomers in a sequence-defined manner via Ugi ...

Lanthanide-Mediated Dephosphorylation Used for Peptide Cleavage during Solid Phase Peptide Synthesis

open access: yesMolecules, 2013
Lanthanide(III) ions can accelerate the hydrolysis of phosphomonoesters and phosphodiesters in neutral aqueous solution. In this paper, lanthanide-mediated dephosphorylation has been applied in aqueous media as an orthogonal cleavage condition that can ...

Synthesis of high-oxidation Y-Ba-Cu-O phases in superoxygenated thin films

open access: yes, 2018
It is known that solid-state reaction in high-pressure oxygen can stabilize high-oxidation phases of Y-Ba-Cu-O superconductors in powder form. We extend this superoxygenation concept of synthesis to thin films which, due to their large surface-to-volume ...
