Identification of a New Ribonucleoside Inhibitor of Ebola Virus Replication

open access: yesViruses, 2015
The current outbreak of Ebola virus (EBOV) in West Africa has claimed the lives of more than 15,000 people and highlights an urgent need for therapeutics capable of preventing virus replication.

AICAr, a Widely Used AMPK Activator with Important AMPK-Independent Effects: A Systematic Review

open access: yesCells, 2021
5-Aminoimidazole-4-carboxamide ribonucleoside (AICAr) has been one of the most commonly used pharmacological modulators of AMPK activity. The majority of early studies on the role of AMPK, both in the physiological regulation of metabolism and in cancer ...

DNA Polymerases Engineered by Directed Evolution to Incorporate Nonstandard Nucleotides

open access: yesFrontiers in Microbiology, 2014
DNA polymerases have evolved for billions of years to accept natural nucleoside triphosphate substrates with high fidelity and to exclude closely related structures, such as the analogous ribonucleoside triphosphates. However, polymerases that can accept

Deoxyribo‐ and Ribonucleoside H‐Phosphonates [PDF]

open access: yesCurrent Protocols in Nucleic Acid Chemistry, 2001
AbstractMost methods for preparing H‐phosphonate monoesters suffer from variable yields and are often incompatible with common protecting groups used in oligonucleotide synthesis. This unit describes four procedures that consistently give high yields of the desired products.

Beta-hydroxyphosphonate ribonucleoside analogues derived from 4-substituted-1,2,3-triazoles as IMP/GMP mimics: synthesis and biological evaluation

open access: yesBeilstein Journal of Organic Chemistry, 2016
A series of seventeen β-hydroxyphosphonate ribonucleoside analogues containing 4-substituted-1,2,3-triazoles was synthesized and fully characterized. Such compounds were designed as potential inhibitors of the cytosolic 5’-nucleotidase II (cN-II), an ...

Characterizing Benzo[a]pyrene Adducts in Transfer RNAs Using Liquid Chromatography Coupled with Tandem Mass Spectrometry (LC-MS/MS)

open access: yesBiomedicines, 2023
The activated forms of the environmental pollutant benzo[a]pyrene (B[a]P), such as benzo[a]pyrene diol epoxide (BPDE), are known to cause damage to genomic DNA and proteins. However, the impact of BPDE on ribonucleic acid (RNA) remains unclear.

Permeability of Coxiella burnetii to ribonucleosides [PDF]

open access: yesMicrobiology, 2002
Knowledge about transport in Coxiella burnetii, an obligate phagolysosomal parasite, is incomplete. The authors investigated the capability of isolated, intact, host-free Coxiella to transport ribonucleosides while incubated at a pH value typical of lysosomes.

NADH‐Reductive Stress Induced by Dihydrolipoamide Dehydrogenase Activation Contributes to Cuproptosis

open access: yesAdvanced Science, EarlyView.
This study demonstrates a cuproptosis mechanism involving nicotinamide adenine dinucleotide (NADH)‐reductive stress in neural cells. Copper activates dihydrolipoamide dehydrogenase under mitochondrial pH, accumulating NADH. Copper also induces mitochondrial permeability transition pore opening, facilitating NADH translocation to the cytosol and ...
