Effect of uridine protecting groups on the diastereoselectivity of uridine-derived aldehyde 5’-alkynylation

Beilstein Journal of Organic Chemistry, 2017
The 5’-alkynylation of uridine-derived aldehydes is described. The addition of alkynyl Grignard reagents on the carbonyl group is significantly influenced by the 2’,3’-di-O-protecting groups (R1): O-alkyl groups led to modest diastereoselectivities (65 ...

Local but Not Systemic Administration of Uridine Prevents Development of Antigen-Induced Arthritis. [PDF]

PLoS ONE, 2015
Uridine has earlier been show to down modulate inflammation in models of lung inflammation. The aim of this study was to evaluate the anti-inflammatory effect of uridine in arthritis.Arthritis was induced by intra-articular injection of mBSA in the knee ...

Protocol for UVC uridine actinometry

MethodsX, 2023
Uridine contains the chromophore uracil, a base forming part of RNA. In the range 240–290 nm, the absorption spectra of uridine and DNA are very similar and correspond to the spectral inactivation sensitivity of almost all microorganisms.

Glucose inhibits cardiac muscle maturation through nucleotide biosynthesis. [PDF]

, 2017
The heart switches its energy substrate from glucose to fatty acids at birth, and maternal hyperglycemia is associated with congenital heart disease. However, little is known about how blood glucose impacts heart formation.

Dihydroorotate dehydrogenase (DHODH) regulates trophoblast syncytialization through organelle stress–induced cellular senescence

FEBS Open Bio, EarlyView.
The inhibition of mitochondrial dihydroorotate dehydrogenase (DHODH) impairs syncytialization and induces cellular senescence via mitochondrial and endoplasmic reticulum stress in human trophoblast stem cells, elevating sFlt1/PlGF levels, a hallmark of placental dysfunction in hypertensive disorders of pregnancy.

The Aging Blood: Cellular Origins, Circulating Drivers, and Therapeutic Potential

Aging and Cancer, EarlyView.
As a conduit linking all organs, the blood system both reflects and actively drives systemic aging. This review highlights how circulating pro‐aging and antiaging factors and age‐associated hematopoietic stem cell dysfunction contribute to immunosenescence and multi‐organ decline, positioning the hematopoietic system as a target for aging intervention.

Unnatural Amino Acid and Emerging Chemistry Approaches to Map RNA–Protein Interactions

Angewandte Chemie, EarlyView.
This review highlights emerging chemistries for mapping RNA–protein interactions, including genetically encoded unnatural amino acids, novel photocrosslinkers, and non‐photoactivatable crosslinking systems. We compare their mechanisms, reactivity and applications, outlining how these next‐generation tools enable higher‐resolution, site‐specific ...

Uridine and its role in metabolic diseases, tumors, and neurodegenerative diseases

Frontiers in Physiology
Uridine is a pyrimidine nucleoside found in plasma and cerebrospinal fluid with a concentration higher than the other nucleosides. As a simple metabolite, uridine plays a pivotal role in various biological processes. In addition to nucleic acid synthesis,
