Recent Advances in Pyrimidine-Based Drugs

open access: yesPharmaceuticals
Pyrimidines have become an increasingly important core structure in many drug molecules over the past 60 years. This article surveys recent areas in which pyrimidines have had a major impact in drug discovery therapeutics, including anti-infectives ...

High expression levels of pyrimidine metabolic rate–limiting enzymes are adverse prognostic factors in lung adenocarcinoma: a study based on The Cancer Genome Atlas and Gene Expression Omnibus datasets

open access: yesPurinergic Signalling Purinergic Signalling, 2020
Reprogramming of metabolism is described in many types of cancer and is associated with the clinical outcomes. However, the prognostic significance of pyrimidine metabolism signaling pathway in lung adenocarcinoma (LUAD) is unclear.

The Ability of Cyanobacterial Cells to Restore UV-B Radiation Induced Damage to Photosystem II is Influenced by Photolyase Dependent DNA Repair [PDF]

open access: yes, 2013
Damage of DNA and Photosystem-II are among the most significant effects of UV-B irradiation in photosynthetic organisms. Both damaged DNA and Photosystem-II can be repaired, which represent important defense mechanisms against detrimental UV-B effects ...

Giant spin canting in the S = 1/2 antiferromagnetic chain [CuPM(NO3)2(H2O)2]n observed by 13C-NMR

open access: yes, 2005
We present a combined experimental and theoretical study on copper pyrimidine dinitrate [CuPM(NO3)2(H2O)2]n, a one-dimensional S = 1/2 antiferromagnet with alternating local symmetry.

De novo prediction of PTBP1 binding and splicing targets reveals unexpected features of its RNA recognition and function. [PDF]

open access: yes, 2014
The splicing regulator Polypyrimidine Tract Binding Protein (PTBP1) has four RNA binding domains that each binds a short pyrimidine element, allowing recognition of diverse pyrimidine-rich sequences.

Targeting pyrimidine synthesis accentuates molecular therapy response in glioblastoma stem cells

open access: yesScience Translational Medicine, 2019
Concurrent targeting of pyrimidine synthesis and oncogenic driver pathways improves therapeutic efficacy in glioblastoma. Targeting metabolic changes in glioblastoma Glioblastoma (GBM) is the most aggressive brain cancer in adults.

Modulating pyrimidine ribonucleotide levels for the treatment of cancer

open access: yesCancer & Metabolism, 2020
By providing the necessary building blocks for nucleic acids and precursors for cell membrane synthesis, pyrimidine ribonucleotides are essential for cell growth and proliferation.

A Benchmark of GW Methods for Azabenzenes: Is the GW Approximation Good Enough?

open access: yes, 2012
Many-body perturbation theory in the GW approximation is a useful method for describing electronic properties associated with charged excitations. A hierarchy of GW methods exists, starting from non-self-consistent G0W0, through partial self-consistency ...

Chemical investigation of light induced DNA bipyrimidine damage and repair [PDF]

open access: yes, 2011
In all organisms, genetic information is stored in DNA and RNA. Both of these macromolecules are damaged by many exogenous and endogenous events, with UV irradiation being one of the major sources of damage.
