Predicting inhibitors for SARS-CoV-2 RNA-dependent RNA polymerase using machine learning and virtual screening [PDF]

open access: yesarXiv, 2020
Global coronavirus disease pandemic (COVID-19) caused by newly identified SARS- CoV-2 coronavirus continues to claim the lives of thousands of people worldwide. The unavailability of specific medications to treat COVID-19 has led to drug repositioning efforts using various approaches, including computational analyses.

Chemical Proteomics Reveals Human Off‐Targets of Fluoroquinolone Induced Mitochondrial Toxicity

open access: yesAngewandte Chemie International Edition, EarlyView.
A schematic overview of the adverse effects of Ciprofloxacin related to mitochondrial toxicity. AIFM1 plays a role in the MIA40‐mediated import into the IMS and oxidative folding of nuclear‐encoded proteins, including ETC complexes I and IV subunits. Ciprofloxacin disrupts the IMS import machinery, impairing ETC function.

Preparation of 4 '-spirocyclobutyl nucleoside analogues as novel and versatile adenosine scaffolds

open access: yes, 2019
Despite the large variety of modified nucleosides that have been reported, the preparation of constrained 4 '-spirocyclic adenosine analogues has received very little attention.

Human Deoxycytidine Kinase Is a Valuable Biocatalyst for the Synthesis of Nucleotide Analogues [PDF]

open access: yes, 2019
Natural ribonucleoside-5’-monophosphates are building blocks for nucleic acids which are used for a number of purposes, including food additives. Their analogues, additionally, are used in pharmaceutical applications.

Ribozyme‐catalyzed site‐specific labeling of RNA using O6‐alkylguanine SNAP‐tag substrates

open access: yesAngewandte Chemie International Edition, Accepted Article.
Site‐specific modification of RNAs with functional handles enables studies of RNA structure, fate, function, and interactions. Ribozymes provide an elegant way to covalently modify an RNA of interest (ROI). Here, we report that the methyltransferase ribozyme MTR1 can be employed as a versatile tool for RNA modification and labeling.

RNA polymerase interactions and elongation rate [PDF]

open access: yesarXiv, 2018
We show that non-steric molecular interactions between RNA polymerase (RNAP) motors that move simultaneously on the same DNA track determine strongly the kinetics of transcription elongation. With a focus on the role of collisions and cooperation, we introduce a stochastic model that allows for the exact analytical computation of the stationary ...

Failure of dideoxynucleosides to inhibit human immunodeficiency virus replication in cultured human macrophages. [PDF]

open access: yes, 1987
Primary human monocyte-derived macrophages (MDM) were shown to have diminished deoxynucleoside kinase activities compared to T lymphoblasts, and a reduced ability to phosphorylate dideoxynucleosides with anti-human immunodeficiency virus (HIV) activity ...

Simultaneous quantification of 12 different nucleotides and nucleosides released from renal epithelium and in human urine samples using ion-pair reversed-phase HPLC [PDF]

open access: yes, 2012
Nucleotides and nucleosides are not only involved in cellular metabolism but also act extracellularly via P1 and P2 receptors, to elicit a wide variety of physiological and pathophysiological responses through paracrine and autocrine signalling pathways.
