Efficient Biocatalytic Synthesis of Dihalogenated Purine Nucleoside Analogues Applying Thermodynamic Calculations [PDF]

open access: yes, 2020
The enzymatic synthesis of nucleoside analogues has been shown to be a sustainable and efficient alternative to chemical synthesis routes. In this study, dihalogenated nucleoside analogues were produced by thermostable nucleoside phosphorylases in ...

Venetoclax and alvocidib are both cytotoxic to acute myeloid leukemia cells resistant to cytarabine and clofarabine

open access: yesBMC Cancer, 2020
Background Cytarabine (ara-C) is the major drug for the treatment of acute myeloid leukemia (AML), but cellular resistance to ara-C is a major obstacle to therapeutic success.

Synthesis of New Fructo – Nucleoside Analogue Derivatives [PDF]

open access: yesKirkuk Journal of Science, 2011
Tow types of nucleoside derivatives have been synthesized. To prepare the first type 1′,3′ ,4′,6′ -Tetra-O-benzoyl-β-D-fructo furanose (F1)with a free hydroxyl group at position-2′ was chosen as the Chiron.

Nucleoside Analogues as Antibacterial Agents [PDF]

open access: yesFrontiers in Microbiology, 2019
The rapid increase in antibiotic-resistant bacteria has emphasized the urgent need to identify new treatments for bacterial infections. One attractive approach, reducing the need for expensive and time-consuming clinical trials, is to repurpose existing clinically approved compounds for use as antibacterial agents.

Biological phosphorylation of an Unnatural Base Pair (UBP) using a Drosophila melanogaster deoxynucleoside kinase (DmdNK) mutant. [PDF]

open access: yesPLoS ONE, 2017
One research goal for unnatural base pair (UBP) is to replicate, transcribe and translate them in vivo. Accordingly, the corresponding unnatural nucleoside triphosphates must be available at sufficient concentrations within the cell. To achieve this goal,

Nucleoside Analogues and Mitochondrial Toxicity [PDF]

open access: yesClinical Infectious Diseases, 2004
An evaluation of the US Food and Drug Administration's Adverse Event Reporting System identified that patients coinfected with human immunodeficiency virus and chronic hepatitis C virus who were treated with a regimen of ribavirin and didanosine, with or without stavudine, were at increased risk for events associated with mitochondrial toxicity ...

Expanding a fluorescent RNA alphabet: synthesis, photophysics and utility of isothiazole-derived purine nucleoside surrogates. [PDF]

open access: yes, 2017
A series of emissive ribonucleoside purine mimics, all comprised of an isothiazolo[4,3-d]pyrimidine core, was prepared using a divergent pathway involving a key Thorpe-Ziegler cyclization.
