A Sustainable Synthetic Approach to Tacrine and Cholinesterase Inhibitors in Deep Eutectic Solvents under Aerobic Conditions

Molecules
An enhanced, sustainable, and efficient method for synthesizing tacrine, achieving a 98% yield, has been developed by replacing volatile organic compounds with more eco-friendly solvents such as deep eutectic solvent (DESs). The optimized protocol scales

One Pot Synthesis of Cubic Gauche Polymeric Nitrogen [PDF]

arXiv
The long sought cubic gauche polymeric nitrogen (cg-N) consisting of N-N single bonds has been synthesized by a simple route using sodium azide as a precursor at ambient conditions. The recrystallization process was designed to expose crystal faces with low activation energy that facilitates initiating the polymeric reaction at ambient conditions.

Modulating Signal Generation in Aptamer‐Based CNT‐FET Biosensors by Controlling the Functionalization Route

Advanced Sensor Research, EarlyView.
The impact of different assembly strategies is discussed on the performance of nanoscale aptamer‐based SWCNT‐FET biosensors. By combining electrical and optical characterization, this is revealed that how aptamer conformation affects local electrostatic changes within the Debye length, leading to distinct sensor responses.

FUS Selectively Facilitates circRNAs Packing into Small Extracellular Vesicles within Hypoxia Neuron

Advanced Science, EarlyView.
This study aimed to unravel the role of FUS in the loading of functional circRNAs into neuronal sEVs under hypoxic conditions, which involves their aggregations in SGs and specific interaction between the FUS Zf_RanBP domain to regulate circRNA sorting in sEVs.

Nitrogen-Centered Radicals Derived from Azidonucleosides

Molecules
Azido-modified nucleosides have been extensively explored as substrates for click chemistry and the metabolic labeling of DNA and RNA. These compounds are also of interest as precursors for further synthetic elaboration and as therapeutic agents.

Nanostructured carbon materials decorated with organophosphorus moieties: synthesis and application

Beilstein Journal of Nanotechnology, 2017
A new synthetic approach for the production of carbon nanomaterials (CNM) decorated with organophosphorus moieties is presented. Three different triphenylphosphine oxide (TPPO) derivatives were used to decorate oxidized multiwalled carbon nanotubes (ox ...
