Metal‐Catalyzed Benzannulation: Recent Advances in Catalyst Design, Mechanistic Insights, and Aromatic Framework Construction

open access: yesThe Chemical Record, EarlyView.
This review offers a contemporary overview of metal‐catalyzed benzannulation (2018–present) encompassing transition, main‐group, post‐transition, and rare‐earth‐metal catalysts. It systematically highlights catalyst design, mechanistic insights, stereo‐ and regioselectivity, and synthetic applications toward aromatic and heteroaromatic scaffolds, while

9-Amino Acridines Undergo Reversible Amine Exchange Reactions in Water: Implications on Their Mechanism of Action in Vivo

open access: yes, 2016
9-Amino substituted acridines undergo a reversible amine exchange reaction in water under near-physiological conditions via an unstable hemiaminal intermediate. This thermodynamically controlled reaction may have implications in understanding the mode of

Conjugation with Acridines Turns Nuclear Localization Sequence into Highly Active Antimicrobial Peptide

open access: yesEngineering, 2015
The emergence of multidrug-resistant bacteria creates an urgent need for alternative antibiotics with new mechanisms of action. In this study, we synthesized a novel type of antimicrobial agent, Acr3-NLS, by conjugating hydrophobic acridines to the N ...

Effects of Roscovitine and Serum Starvation on the Viability and G0/G1 Synchronization in Somatic Cells from the Antillean Manatee (Trichechus manatus manatus, Linnaeus 1758)

open access: yesZoo Biology, EarlyView.
ABSTRACT The success of nuclear reprogramming techniques, including the G0/G1 synchronization of somatic cells, depends on species‐specific optimization. While roscovitine and serum starvation have been successfully applied in domestic and wild terrestrial mammals, their use in aquatic mammals remains poorly investigated.

Non-aggregating solvatochromic bipolar benzo[f]quinolines and benzo[a]acridines for organic electronics

open access: yes, 2012
A novel series of light emitting and thermally stable non-aggregating benzannulated quinolines and acridines were designed and prepared from ketene-S,S-acetal under mild conditions through C–C bond formation. Photophysical and electrochemical analyses of

Associations Between Sperm DNA Fragmentation and Lifestyle Factors

open access: yesAndrology, EarlyView.
ABSTRACT Background Sperm DNA fragmentation index (DFI) has been proposed as a supplementary biomarker to traditional semen parameters in the evaluation of male infertility. However, its determinants and clinical relevance remain unclear, particularly regarding modifiable lifestyle factors.

Ammonia Accumulation Drives Intervertebral Disc Degeneration by Triggering Ammonia‐Induced Cell Death Through Lysosome–Mitochondria Crosstalk

open access: yesCell Proliferation, EarlyView.
Mechanical strain disrupts the lysosome‐mitochondria axis via GLS1‐mediated ammonia toxicity, causing NP cell death and ECM breakdown in IVDD. CB839‐mediated GLS1 inhibition effectively rescues cellular homeostasis and alleviates disc degeneration.

Circadian rhythms of metabolite abundance in Drosophila are largely driven by time of feeding

open access: yesThe FEBS Journal, EarlyView.
Circadian clocks exist in the brain and peripheral tissues such as the Drosophila fat body. Single‐nuclei transcriptomics reveal that the fat body clock generates time‐of‐day differences in metabolic gene transcription, which may also be indirectly controlled by brain clocks.
