Crystal structure of 5-(dibenzofuran-4-yl)-2′-deoxyuridine

Acta Crystallographica Section E: Crystallographic Communications, 2017
The molecule of the title compound, C21H18N2O6, has a bent rather than a linear conformation supported by three intramolecular C—H...O hydrogen bonds. The packing in the crystal lattice is largely determined by interactions between hydrogen atoms with ...

Radiosensitizing Nucleosides [PDF]

JNCI Journal of the National Cancer Institute, 1996
Chemotherapeutic drugs that perturb nucleotide metabolism have the potential to produce substantial sensitization of tumor cells to radiation treatment. The process is called radiosensitization, and the agents that induce it are called radiosensitizers.

Strained Conformations of Nucleosides in Active Sites of Nucleoside Phosphorylases [PDF]

Biomolecules, 2020
Nucleoside phosphorylases catalyze the reversible phosphorolysis of nucleosides to heterocyclic bases, giving α-d-ribose-1-phosphate or α-d-2-deoxyribose-1-phosphate. These enzymes are involved in salvage pathways of nucleoside biosynthesis. The level of these enzymes is often elevated in tumors, which can be used as a marker for cancer diagnosis. This

Delivery of Islatravir via High Drug‐Load, Long‐acting Microarray Patches for the Prevention or Treatment of Human Immunodeficiency Virus

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Islatravir‐loaded dissolving microarray patches (MAPs) provide a minimally invasive, long‐acting solution for HIV‐1 prevention and treatment. In rats, sustained islatravir delivery lasts up to three months, while in minipigs, efficacious plasma levels are detected for six days.

The role of alkyl substituents in deazaadenine-based diarylethene photoswitches

Beilstein Journal of Organic Chemistry, 2016
Diarylethenes are an important class of reversible photoswitches and often claimed to require two alkyl substituents at the carbon atoms between which the bond is formed or broken in the electrocyclic rearrangement.

Interaction of Oligonucleotides with Gold Nanoparticles: Factors Beyond Electrostatic and Van‐Der Waals Forces

Advanced Materials Interfaces, EarlyView.
The formation of stable clusters of gold nanoparticles with oligonucleotides at different solution conditions is explored. DNA base homogeneity and strand directionality influence the binding with gold nanoparticles leading to interesting clustering behavior that can be relevant for SERS applications.
