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

Chemistry – 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.

Mini‐Hairpin DNA: Extraordinarily Stable Structure and Its Applications

Chemistry – A European Journal, EarlyView.
Mini‐hairpin DNA fragments containing GCGAAGC and GCGAAAGC form exceptionally stable hairpin‐like structures, with only two G−C pairs and one sheared G−A pair, remaining undenatured in 7 M urea and resisting nuclease digestion. These mini‐hairpin sequences frequently appear in replication and transcription origins, influence DNA sequencing fidelity ...

Bottom‐up Strategies for Generating Polymer Protocells That Mimic Cellular Communication

Chemistry – A European Journal, EarlyView.
This review focuses on polymeric protocells produced using a bottom‐up approach. Polymer‐based assemblies guarantee stability and designability by adjusting the properties of the amphiphilic copolymers used. The review covers protocell architectures, production, and their intra‐ and intercellular communication mechanisms.

Rational Design Strategies for Stimuli‐Responsive DNAzymes Using Modified and Artificial Nucleotides

Chemistry – A European Journal, EarlyView.
Activity control of RNA‐cleaving DNAzymes in response to external stimuli has attracted growing interest for applications in DNA‐based diagnostics, therapeutics, and dynamic DNA nanotechnology. This review summarizes rational design strategies for stimuli‐responsive DNAzymes using modified or artificial nucleotides, including split and caged DNAzymes ...

Advancing Maternal Health with Long‐Acting Therapeutics: Priorities, Efficacy and Safety Considerations, and Emerging Technologies

Clinical Pharmacology &Therapeutics, EarlyView.
Maternal health remains a critical global concern, particularly in underserved populations and in low‐ and middle‐income countries where access to safe and effective therapeutics is limited. Despite the use of medications by most women during pregnancy, the exclusion of pregnant and lactating women from clinical trials has resulted in significant data ...

Interpretation of in vitro concentration‐response data for risk assessment and regulatory decision‐making: Report from the 2022 IWGT quantitative analysis expert working group meeting

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...

Advances in Double‐Stranded DNA Targeting Technologies

Exploration, EarlyView.
Double‐stranded DNA (dsDNA) plays a crucial role in genetic information storage and disease management, but its inherent stability limits access to internal bases. To overcome this challenge, various high‐specificity molecular targeting technologies have been developed to destabilize the DNA structure.

Identification of Natural and Artificial Modifications in DNA at the Nanometer Level

Journal of Raman Spectroscopy, EarlyView.
Short single‐ and double‐stranded DNA sequences with natural and artificial markers are examined at ambient conditions using TERS to identify and localize the labelled nucleobases. The differences between single‐ and double‐stranded DNA should provide clear experimental evidence of the extreme surface sensitivity of TERS.

Atypical Wounds in Chronic Graft‐Versus‐Host Disease and Peripheral Arterial Disease Caused by Tyrosine Kinase Inhibitors

JEADV Clinical Practice, EarlyView.
ABSTRACT The term “atypical wounds” primarily refers to lesions with immunological or cancerous etiologies. However, these wounds can also be drug‐induced. We report about a 32‐year‐old man with a 6‐year history of chronic myelogenous leukemia (CML) and chronic graft‐versus‐host disease (cGvHD) following an HLA‐compatible allogeneic stem cell ...
