Pyridine-Catalyzed Double C–N Coupling Reaction of an Isocyanate with Two Benzynes

open access: yes, 2011
A pyridine-catalyzed double C–N bond cross-coupling reaction involving two benzynes with an isocyanate was carried out. The coupling reaction proceeded through a unique pathway involving the formation of an unstable carbamic acid intermediate and facile ...

Photoinduced C-C Cross-Coupling of Aryl Chlorides and Inert Arenes

open access: yesInternational Journal of Photoenergy, 2016
Here we report a facile, efficient, and catalyst-free method to realize C-C cross-coupling of aryl chlorides and inert arenes under UV light irradiation.

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

open access: yesMolecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

(In-)stability and stabilisation of QNL-type atomistic-to-continuum coupling methods [PDF]

open access: yes, 2014
We study the stability of ghost force-free energy-based atomistic-to-continuum coupling methods. In 1D we essentially complete the theory by introducing a universally stable a/c coupling as well as a stabilisation mechanism for unstable coupling schemes.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Palladium(0) Deposited on PAMAM Dendrimers as a Catalyst for C–C Cross Coupling Reactions

open access: yesMolecules, 2011
PAMAM dendrimers of generations G2–G3 as well as a partially substituted derivative of generation G4 and a low-molecular-weight tricyclic ligand 4 were used to bind Pd(0) nanoparticles. The obtained adducts were tested as catalysts for C–C cross-coupling

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Photoredox/Nickel Dual Catalysis for C(sp2)-C(sp3) Cross Electrophile Coupling Reaction Using Phenols and Alcohols as the Latent Electrophile Sources

open access: yes
Introducing alkyl groups, particularly through innovative C(sp2)-C(sp3) bond-forming methods utilizing abundant feedstocks, holds promise for expanding chemical diversity, especially in drug discovery programs.
