The major role of Listeria monocytogenes folic acid metabolism during infection is the generation of N-formylmethionine

open access: yesmBio, 2023
Folic acid and its derivatives (folates) play central roles in one-carbon metabolism, necessary for the synthesis of purines, pyrimidines, and some amino acids.

Ferrocenoyl-adenines: substituent effects on regioselective acylation

open access: yesBeilstein Journal of Organic Chemistry, 2022
A series of N6-substituted adenine–ferrocene conjugates was prepared and the reaction mechanism underlying the synthesis was explored. The SN2-like reaction between ferrocenoyl chloride and adenine anions is a regioselective process in which the product ...

Assessment of the temporal trend and daily profiles of the dietary purine intake among Chinese residents during 2014 to 2021

open access: yesFrontiers in Nutrition, 2023
The incidence of hyperuricemia is on the rise in China, primarily due to dietary habits. However, limited data exists regarding dietary purine intake in the country.

The Intersection of Purine and Mitochondrial Metabolism in Cancer

open access: yesCells, 2021
Nucleotides are essential to cell growth and survival, providing cells with building blocks for DNA and RNA, energy carriers, and cofactors. Mitochondria have a critical role in the production of intracellular ATP and participate in the generation of ...

Biosensor measurement of purine release from cerebellar cultures and slices [PDF]

open access: yes, 2010
We have previously described an action-potential and Ca2+-dependent form of adenosine release in the molecular layer of cerebellar slices. The most likely source of the adenosine is the parallel fibres, the axons of granule cells. Using microelectrode

Structure-Based Design of 2-Aminopurine Derivatives as CDK2 Inhibitors for Triple-Negative Breast Cancer

open access: yesFrontiers in Pharmacology, 2022
Cyclin-dependent kinase 2 (CDK2) regulates the progression of the cell cycle and is critically associated with tumor growth. Selective CDK2 inhibition provides a potential therapeutic benefit against certain tumors. Purines and related heterocycle (e.g.,

Coagulase-negative staphylococci release a purine analog that inhibits Staphylococcus aureus virulence

open access: yesNature Communications, 2021
Coagulase-negative staphylococci and Staphylococcus aureus colonize similar niches in mammals and conceivably compete for space and nutrients. Here, we report that a coagulase-negative staphylococcus, Staphylococcus chromogenes ATCC43764, synthesizes and

The purine nucleoside phosphorylase pnp-1 regulates epithelial cell resistance to infection in C. elegans

open access: yesbioRxiv, 2021
Intestinal epithelial cells are subject to attack by a diverse array of microbes, including intracellular as well as extracellular pathogens. While defense in epithelial cells can be triggered by pattern recognition receptor-mediated detection of microbe-

Human de novo Purine Biosynthesis

open access: yesCritical reviews in biochemistry and molecular biology, 2020
The focus of this review is the human de novo purine biosynthetic pathway. The pathway enzymes are enumerated, as well as the reactions they catalyze and their physical properties. Early literature evidence suggested that they might assemble into a multi-

Evolutionary Trends in RNA Base Selectivity Within the RNase A Superfamily

open access: yesFrontiers in Pharmacology, 2019
There is a growing interest in the pharmaceutical industry to design novel tailored drugs for RNA targeting. The vertebrate-specific RNase A superfamily is nowadays one of the best characterized family of enzymes and comprises proteins involved in host ...
