Introduction of a Double‐Headed Nucleotide Into G‐Quadruplex DNA: Position‐Dependent Stabilization and Structural Insights

open access: yesChemistry – A European Journal, EarlyView.
A double‐headed bis‐guanine (G) nucleotide (GG) was evaluated as a noncanonical building block in G‐quadruplexes (G4s). Biophysical and computational analyses reveal that GG can directly participate in G‐tetrads and strongly stabilize G4s in a position‐ and topology‐dependent manner. These findings establish design rules for using GG to engineer highly

Purine metabolism rewiring improves glioblastoma susceptibility to temozolomide treatment

open access: yesCell Death and Disease
Glioblastoma (GBM) is among the deadliest cancers, characterized by poor prognosis and median survival of 12–15 months post-diagnosis. Despite aggressive therapeutic regimens, GBM treatment is still an unmet clinical need due to heterogeneity ...

Phosphonomethyl (Thio)Phosphonamidite Reagents for the Construction of Phosphonylmethyl Phosphono(Di)Thioate Mono‐ and Diesters

open access: yesChemistry – A European Journal, EarlyView.
A set of new phosphonomethyl (thio)phosphonamidite reagents is introduced to generate unprecedented pyrophosphate mimetics. The versatile P(III)‐P(V) reagents allow for the construction of various pyrophosphate isosteres, and the applicability of the chemistry is illustrated in the assembly of a diverse set of stabilized CDP‐glycerol and CDP‐ribitol ...

Uncatalyzed Guanosine Phosphorylation under Potentially Prebiotic Conditions

open access: yesChemistry – A European Journal, EarlyView.
Pyrophosphate acts as phosphorylating agent of guanosine under simple wet‐dry cycles without condensing agent and inorganic catalysts to afford cyclic guanosine monophosphate derivatives useful for oligomerization in prebiotic processes. ABSTRACT The phosphorylation of nucleosides and their subsequent polymerization are key issues in the study of the ...

Expression, Purification, and Microscopy‐Based Assays for Engineered Recombinant Tyrosinated, Detyrosinated, and Δ2 Human Tubulin

open access: yesCytoskeleton, EarlyView.
ABSTRACT Microtubules are noncovalent polymers assembled from α/β tubulin dimers. Their structure, dynamics and interaction with effectors are regulated through the expression of diverse tubulin isotypes and chemically diverse posttranslational modifications, also known as the “tubulin code.” Understanding the biophysical correlates between tubulin ...

Multiscale Modeling of an 8‐Week Combination Regimen of Bemnifosbuvir and Ruzasvir in Patients with Chronic Hepatitis C Virus Infection

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Bemnifosbuvir (BEM) and ruzasvir (RZR) are pan‐genotypic HCV polymerase (NS5B) and NS5A inhibitors, respectively. In a single‐arm study (NCT05904470), 215 treatment‐naïve, adherent participants with chronic HCV (with or without cirrhosis) received BEM 550 mg QD plus RZR 180 mg QD for 8 weeks.

Whole-genome analysis of Bacillus paranthracis YC06 isolated from healthy individual feces for biodegrading inosine and guanosine

open access: yesBMC Microbiology
The overproduction of uric acid, driven by its key precursors (inosine and guanosine), leads to hyperuricemia, a metabolic disorder associated with severe complications such as gout and renal dysfunction.

Commonalities of platelet dysfunction in heart failure with preserved ejection fraction and underlying comorbidities

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1013-1028, April 2025.
Abstract Heart failure with preserved ejection fraction (HFpEF) is characterized by a lack of a specific targeted treatment and a complex, partially unexplored pathophysiology. Common comorbidities associated with HFpEF are hypertension, atrial fibrillation, obesity and diabetes.

Cardiac remodelling in the era of the recommended four pillars heart failure medical therapy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1029-1044, April 2025.
Abstract Cardiac remodelling is a key determinant of worse cardiovascular outcome in patients with heart failure (HF) and reduced ejection fraction (HFrEF). It affects both the left ventricle (LV) structure and function as well as the left atrium (LA) and the right ventricle (RV).

Cilostazol in patients with heart failure and preserved ejection fraction—The CLIP‐HFpEF trial

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1437-1446, April 2025.
• Cilostazol is an oral PDE‐3 inhibitor that may have advantageous effects in heart failure with preserved ejection fraction (HFpEF). • Cilostazol significantly improved short‐term heart failure‐related health status scores (KCCQ‐12) and NT‐proBNP levels when compared to placebo.
