Degrees of Sulfonation: Mapping the Reactivity Landscape of Acridine and Acridone

Organics
Although sulfonated acridines and acridones are valuable scaffolds in diagnostics and materials science, to our best knowledge, there is no comprehensive study that addresses how the degree of sulfonation depends on reaction parameters. To fill this gap,

Interaction of Bioactive Pyrazolo[4,3-a]acridines with Human Serum Albumin [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2017
Several heterocyclic bioactive fluorescent 3-alkyl-3H-pyrazolo[4,3-a]acridin-11-carbonitriles were conveniently synthesized from the reaction of 1-alkyl-1H-indazoles with different aryl acetonitrile in basic methanol solution in good yields.

Cyclin‐dependent kinase 13 is indispensable for normal mouse heart development

Journal of Anatomy, Volume 246, Issue 4, Page 616-630, April 2025.
Congenital heart disease (CHD) is the most common defect in live births. The role of cyclin‐dependent kinase (CDK13) in cardiogenesis and CHD was studied using a transgenic mouse model (Cdk13tm1b) carrying deletion of exons 3 and 4, causing loss of function.

Photoprotective potential of gadusol against ultraviolet B radiation in melanocytes

Photochemistry and Photobiology, EarlyView.
Gadusol protects melanocytes from ultraviolet B (UVB)‐induced damage without cytotoxicity. Abstract The increasing incidence of skin cancer, including melanoma, combined with the need for ultraviolet (UV) filters that are safe for human health and marine ecosystems, is driving the search for new photoprotective agents.

Zebrafish as a practical and convenient model for the study of photodynamic and photothermal therapy of solid tumors: A scoping review

Photochemistry and Photobiology, EarlyView.
Zebrafish provide a high‐throughput, optically transparent platform for cancer and drug screening. Their ~80% genetic homology, xenograft compatibility, and transgenic strains enable targeted photosensitizer screening, real‐time ROS and tumor imaging, and mechanistic assays, while fish embryo acute toxicity (FET) and in vitro tests streamline toxicity ...

Phenothiazinium photoantimicrobials with basic side chains [PDF]

Derivatives of the standard cationic photosensitiser, methylene blue, were synthesised, having extra amino (basic) functionality in the auxochromic side-chain. The resulting analogues were profiled for photodynamic activity in vitro, and screened against
