Carbamate-Based Bolaamphiphile as Low-Molecular-Weight Hydrogelators

open access: yesGels, 2016
A new bolaamphiphile analog featuring carbamate moieties was synthesized in six steps starting from thymidine. The amphiphile structure exhibits nucleoside-sugar polar heads attached to a hydrophobic spacer via carbamate (urethane) functions.

Structure Characterization of Escherichia coli Pseudouridine Kinase PsuK

open access: yesFrontiers in Microbiology, 2022
Pseudouridine (Ψ) is one of the most abundant RNA modifications in cellular RNAs that post-transcriptionally impact many aspects of RNA. However, the metabolic fate of modified RNA nucleotides has long been a question. A pseudouridine kinase (PsuK) and a

Moving breathers in bent DNA with realistic parameters [PDF]

open access: yesMod. Phys. Lett. B. 18(25):1319-1326, 2004, 2004
Recent papers have considered moving breathers (MBs) in DNA models including long range interaction due to the dipole moments of the hydrogen bonds. We have recalculated the value of the charge transfer when hydrogen bonds stretch using quantum chemical methods which takes into account the whole nucleoside pairs.

Nucleoside-modified mRNA immunization elicits influenza virus hemagglutinin stalk-specific antibodies

open access: yesNature Communications, 2018
Currently available influenza virus vaccines have inadequate effectiveness and are reformulated annually due to viral antigenic drift. Thus, development of a vaccine that confers long-term protective immunity against antigenically distant influenza virus

Structural basis of nucleoside and nucleoside drug selectivity by concentrative nucleoside transporters

open access: yeseLife, 2014
Concentrative nucleoside transporters (CNTs) are responsible for cellular entry of nucleosides, which serve as precursors to nucleic acids and act as signaling molecules. CNTs also play a crucial role in the uptake of nucleoside-derived drugs, including anticancer and antiviral agents.

Nucleic Acid Based Fluorinated Derivatives: New Tools for Biomedical Applications

open access: yesApplied Sciences, 2012
Nucleic acid-based fluorinated derivatives, e.g., nucleosides or oligonucleotides connected to highly fluorinated chains or labeled with one or more fluorine atoms, have been investigated recently due to their high potential for biomedical applications ...

Mesoscopic modeling for nucleic acid chain dynamics [PDF]

open access: yesPhys. Rev. E, 71 art. num. 051902 (2005), 2005
To gain a deeper insight into cellular processes such as transcription and translation, one needs to uncover the mechanisms controlling the configurational changes of nucleic acids. As a step toward this aim, we present here a novel mesoscopic-level computational model that provides a new window into nucleic acid dynamics.

Determination of total potentially available nucleosides in bovine milk [PDF]

open access: yes, 2010
Bovine colostrum and milk samples were collected from two herds over the course of the first month post-partum, pooled for each herd by stage of lactation and total potentially available nucleosides were determined.

Mechanochemistry of nucleosides, nucleotides and related materials

open access: yesBeilstein Journal of Organic Chemistry, 2018
The application of mechanical force to induce the formation and cleavage of covalent bonds is a rapidly developing field within organic chemistry which has particular value in reducing or eliminating solvent usage, enhancing reaction rates and also in ...

5-aza-2′,2′-Difluoro Deoxycytidine (NUC013): A Novel Nucleoside DNA Methyl Transferase Inhibitor and Ribonucleotide Reductase Inhibitor for the Treatment of Cancer

open access: yesPharmaceuticals, 2017
Tumor suppressor genes can be silenced genetically as well as epigenetically. One approach to reversing epigenetic suppression of tumor suppressor genes is to inhibit DNA methyl transferase.
