Cu(I) Is a Game Changer in the Arrest of Cu(Aβ)‐Induced ROS Production in the Presence of Competing Zn(II) Ions

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT ROS production due to Cu(amyloid‐β) redox cycling is proposed to contribute to the oxidative stress observed in Alzheimer's disease brains. We previously reported on a nitrogen and sulfur‐containing ligand, L, able to arrest Cu(Aβ)‐induced ROS production [Chem. Eur. J. 2023, 29,].

Catalytic Amyloids: Turning Fibrils Into Biocatalysts

open access: yesChemistry – A European Journal, EarlyView.
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as

Highly Potent Fluorogenic Ligands for Triplex DNA: 5‐Substituted 2‐(Naphthalen‐2‐yl)‐4H‐Chromen‐4‐Ones

open access: yesChemistry – A European Journal, EarlyView.
5‐Substituted 2‐(naphthalen‐2‐yl)‐4H‐chromen‐4‐ones are reported as a novel class of highly potent and selective triplex DNA ligands. These ligands induce triplex formation at submicromolar concentrations and inhibit enzymatic activity via ligand‐mediated triplex formation.

Ambident Reactivity in the Phenyl + NO Radical Recombination

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT The recombination reaction of nitric oxide (NO) with radicals via its oxygen atom, rather than the more common nitrogen site, offers an intriguing pathway to the formation of oxynitrenes. The photochemical isomerization of nitroso compounds into their corresponding oxynitrenes may involve such a step.

Lesions Associated With Autism Symptoms Map to a Cerebellar Brain Network in Tuberous Sclerosis Complex

open access: yesAnnals of the Child Neurology Society, EarlyView.
ABSTRACT Objective Autism spectrum disorder (ASD) affects 1 in 36 individuals in the United States and is characterized by impaired social communication and restrictive/repetitive behaviors. Individuals with tuberous sclerosis complex (TSC) have a high incidence of ASD (40%) and exhibit congenital brain lesions (tubers), offering a unique lesion‐based ...

Clinical assessment of mocravimod as a victim of drug–drug interactions via CYP3A4 metabolism and transporters

open access: yesClinical Pharmacology in Drug Development, EarlyView.
Abstract Mocravimod, a novel immunomodulator targeting sphingosine‐1‐phosphate receptor (S1PR), is being developed as a maintenance treatment for patients with acute myeloid leukemia undergoing allogeneic hematopoietic cell transplantation. Preclinical data suggested that cytochrome (CYP) 3A4 is the primary enzyme involved in mocravimod metabolism.

Population Pharmacokinetic and Exposure‐Efficacy Analysis of Baloxavir Marboxil for Influenza Treatment and Post‐Exposure Prophylaxis in Children

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Baloxavir acid (baloxavir), the active metabolite of the prodrug baloxavir marboxil, is a selective inhibitor of the influenza virus cap‐dependent endonuclease. The population pharmacokinetic (popPK) profile of baloxavir in adults/adolescents has been described previously.

Clinical Pharmacogenetics Implementation Consortium (CPIC) Guideline for Thiopurine Dosing Based on TPMT and NUDT15 Genotypes: 2025 Update

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Thiopurine methyltransferase (TPMT) and Nudix hydrolase 15 (NUDT15) are key enzymes that catabolize thiopurines. Decreased or no‐function alleles in TPMT and NUDT15 are associated with reduced or no enzyme activity and predictive of pronounced adverse effects, including severe myelosuppression, that may occur among individuals treated with standard ...
