Mapping the effect of configuration and protecting group pattern on glycosyl acceptor reactivity

Chemical Science, 2023
The reactivity of the acceptor alcohol can have a tremendous influence on the outcome of a glycosylation reaction, both in terms of yield and stereoselectivity.

Inductive Effects on Intramolecular Hydrogen Bond Strength: An Investigation of the Effect of an Electron-Withdrawing CF3 Group Adjacent to an Alcohol Hydrogen Bond Donor

Journal of Physical Chemistry A, 2023
This combined experimental and theoretical study seeks to determine the role that inductive effects have on hydrogen bonds by an investigation into the change in intramolecular hydrogen bond strength in 2-amino-1-trifluoromethylethanol (2ATFME) relative ...

Advances in DNA, histone, and RNA methylation mechanisms in the pathophysiology of alcohol use disorder

Advances in Drug and Alcohol Research, 2023
Alcohol use disorder (AUD) has a complex, multifactorial etiology involving dysregulation across several brain regions and peripheral organs. Acute and chronic alcohol consumption cause epigenetic modifications in these systems, which underlie changes in

Holding your liquor: Comparison of alcohol-induced psychomotor impairment in drinkers with and without alcohol use disorder.

Alcohol, 2023
BACKGROUND Behavioral tolerance to alcohol underscores the widely accepted notion that individuals who regularly drink alcohol become less sensitive to its impairing effects.

Highly Chemoselective Catalytic Photooxidations Using Solvent as a Sacrificial Electron Acceptor.

Chemistry, 2022
Catalyst recovery is an integral part of photoredox catalysis. It is often solved by adding another component-a sacrificial agent- whose role is to convert the catalyst back into its original oxidation state.

Sulfur hydrogen bonding and internal dynamics in the monohydrates of thenyl mercaptan and thenyl alcohol.

Physical Chemistry, Chemical Physics - PCCP, 2020
The monohydrates of thenyl alcohol and thenyl mercaptan have been probed in a supersonic jet expansion using chirped-pulse and Fabry-Perot Fourier-transform microwave spectroscopy.

Analysis on topological alterations of functional brain networks after acute alcohol intake using resting-state functional magnetic resonance imaging and graph theory

Frontiers in Human Neuroscience, 2022
Aims Alcohol consumption could lead to a series of health problems and social issues. In the current study, we investigated the resting-state functional brain networks of healthy volunteers before and after drinking through graph-theory analysis, aiming ...

Modulating donor-acceptor transition energies in phosphorus-boron co-doped silicon nanocrystals via X- and L-type ligands.

Faraday discussions, 2020
In this work, we explore the effect of ligand binding groups on the visible and NIR photoluminescent properties within phosphorus-boron co-doped silicon nanocrystals (PB:Si NCs) by exploiting both the X-type (covalent) and L-type (Lewis donor molecule ...

The mechanisms underlying alcohol-induced decreased splenic size: A network meta-analysis study.

Alcohol, clinical & experimental research, 2023
BACKGROUND Organ weight change is widely accepted as a measure of toxicologic pathology. We and other groups have shown that excessive alcohol exposure leads to decreased spleen weight in rodents.
