Synthesis, Structural and Biological Analysis of Organized Biomimetic Systems [PDF]

open access: yes, 2010
As a part of a program for foldamer design two β-turn mimetics (3S)-amino-5-(carboxylmethyl)-2,3-dihydro-1,5-benzothiazepin-4(5H)-one or DBT and 2-aminomethyl-phenyl-acetic acid or AMPA were selected as frameworks from a molecular modeling study for ...

Evaluating the involvement of autolysosomes in the nuclear translocation of fluorescent proteins

open access: yesFEBS Open Bio, EarlyView.
Endogenously expressed fluorescent proteins can be degraded by autophagy and transported to cell nuclei via the nuclear pore complex. But in some cell lines, for example, HeLa cells which are positive for immunoreactivity of a receptor ligand, such as UCN I, in cell nuclei, fusion of autolysosome with the nuclear envelope is involved in the nuclear ...

Characterisation of cell‐penetrating peptide‐mediated peptide delivery [PDF]

open access: yesBritish Journal of Pharmacology, 2005
Cell‐penetrating peptides such as antennapedia, TAT, transportan and polyarginine have been extensively employed for in vitro and in vivo delivery of biologically active peptides. However, little is known of the relative efficacy, toxicity and uptake mechanism of individual protein transduction domain–peptide conjugates, factors that will be critical

Application of CPPs for Brain Delivery

open access: yes, 2015
Cell-penetrating peptides provide a promising strategy for delivery of drugs across the blood-brain barrier. Here, we present an overview of CPP and peptide-mediated delivery to the central nervous system as well as a Transwell in vitro model to evaluate

Yeast Gcn2 retains activity following humanization of its auto‐phosphorylation region

open access: yesFEBS Open Bio, EarlyView.
Using Saccharomyces cerevisiae as a model to study Gcn2 activation and regulation is limited by the lack of antibodies detecting phosphorylated Gcn2. To overcome this, we engineered Gcn2‐HsC, a yeast Gcn2 variant recognizable by commercial anti‐human phospho‐GCN2 antibodies.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Design and biological characterization of novel cell-penetrating peptides preferentially targeting cell nuclei and subnuclear regions

open access: yesBeilstein Journal of Organic Chemistry, 2018
Within this study, we report about the design and biological characterization of novel cell-penetrating peptides (CPPs) with selective suborganelle-targeting properties.

A brief introduction to cell‐penetrating peptides [PDF]

open access: yesJournal of Molecular Recognition, 2003
Abstract Cell membranes act as protective walls to exclude most molecules that are not actively imported by living cells. This is an efficient way for a cell to prevent uncontrolled influx or efflux of solutes, which otherwise would be harmful to it. Only compounds within a narrow range of molecular size, polarity

Fluorination: A strategy to tune the interactions of molecules and nanoscale systems with biological matter

open access: yesFEBS Open Bio, EarlyView.
This minireview explores fluorination as a key strategy to optimize therapeutic molecules and nanocarriers. By incorporating different fluorinated motifs—from single atoms to linear and branched chains—drug delivery, cellular uptake, and colloidal stability can be improved and fine‐tuned.
