8-Hydroxyquinoline benzoates as highly sensitive fluorescent chemosensors for transition metal ions [PDF]

, 2005
8-Hydroxyquinoline benzoates were developed as a new set of 8-HQ derivatives for highly sensitive fluorescent chemosensors for transition metal ions. A prominent fluorescence enhancement was found in the presence of transition metal ions such as Hg2+ and

Ipriflavone From Aquilaria malaccensis Lam. Exosome‐Like Nanoparticles Targets Prolyl Hydroxylase Domain Protein 2 (PHD2) to Enhance Hypoxia‐Inducible Factor‐α (HIF‐α) Hydroxylation Thereby Alleviating Hypoxia‐Induced Gastrointestinal Mucosal Ferroptosis

MedComm, Volume 7, Issue 4, April 2026.
Ipriflavone (Ipr), an active component of Aquilaria malaccensis Lam. exosome‐like nanoparticles (AELNs), significantly reduces hypoxia‐inducible factor‐α (HIF‐α) expression by enhancing the prolyl hydroxylase domain protein 2 (PHD2)‐mediated hydroxylation of HIF‐α, thereby downregulating HIF‐α‐induced polyunsaturated fatty acid‐phospholipids (PUFA‐PLs),

In vitro selective growth-inhibitory effect of 8-hydroxyquinoline on Clostridium perfringens versus Bifidobacteria in a medium containing chicken ileal digesta [PDF]

, 2016
Clostridium perfringens-induced necrotic enteritis is generally controlled by antibiotics. However, because of increasing antibiotic resistance, other antibacterial agents are required, preferably ones that do not affect the beneficial intestinal ...

Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria‐Algae Interactions

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

New Phytologist, Volume 250, Issue 1, Page 629-647, April 2026.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

Investigation of the substituent effect on the excited- state intramolecular proton transfer of 8-hydroxyquinoline

Results in Chemistry
Fluorescent sensors operating on the excited-state intramolecular proton transfer (ESIPT) mechanism have demonstrated excellent sensing performance owing to their attributes such as large Stokes shifts and excellent photostability.

On a Fluorescent Dye for Indicator Displacement From Cucurbit[7]uril‐Based Molecular Recognition: A Joint Experimental‐Computational Study

ChemPhysChem, Volume 27, Issue 6, 27 March 2026.
The host–guest complexation of a new fluorescent probe called 7‐(diethylamino)‐4‐hydroxyquinoline‐2(1H)‐one (QD) and its inclusion complex with the Cucurbit[7]uril (CB7) macrocycle were studied within a joint experimental and computational study. Confinement alters the photophysical properties of the synthesized quinolinone derivative also offering a ...
