A Constellation of Fluorescent Biosensors to Illuminate the Galaxy of Protein Kinases

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Protein kinases (PKs) are enzymes that catalyze phosphorylation of protein substrates involved in a wide variety of biological signalling pathways. This review describes the different families and mechanisms of action and regulation of protein kinases, together with the different classes of fluorescent biosensors that have been engineered and ...

Molecular Structure of Heterocycles: 6. Solvent Effects on the 17O Nmr Chemical Shifts of 5-Trichloromethylisoxazoles

Journal of the Brazilian Chemical Society, 2001
A multilinear-regression analysis using the Kamlet-Abboud-Taft (KAT) solvatochromic parameters in order to elucidate and quantify the solvent effects on the 17O chemical shifts of three 5-trichloromethylisoxazoles [(1a) non-, (1b) 3-methyl- and (1c) 4 ...

π‐Extended Chiral Molecular Triangular Prisms Exhibiting Boosted Circularly Polarized Luminescence Upon Self‐Assembly

Aggregate, Volume 7, Issue 6, June 2026.
A pair of π‐extended chiral triangular prisms based on pyromellitic diimide is synthesized from enantiopure macrocyclic precursors. They exhibit orange fluorescence and solvent‐dependent self‐assembly, enabling chiroptical inversion and amplification with |glum| values up to 1.15 × 10−2. Single‐crystal structures reveal solvent‐controlled conformations

Preferential Solvation in Alkan-1-ol/Alkylbenzoate Binary Mixtures by Solvatochromic Probes

, 2016
The binary mixtures of methanol with (C1–C4) alkylbenzoates and of (C1, C3, C5, C7, C9, C11) alkan-1-ols with methylbenzoate were used as solvents to look into the preferential solvation and intermolecular interactions of the solvatochromic indicators 2 ...

Evaluation of Photophysical Properties and Biological Applications of Diarylmethanes

ChemistryOpen, Volume 15, Issue 6, June 2026.
The wide applications of diarylmethanes were investigated through various experimental and computational approaches. The solvent environment influences the electronic properties of diarylmethanes and hence their drug‐like properties. Interactions with PARP1 revealed stable binding supporting anticancer potential.

Synthesis, Photophysical Characterization, and Anticancer Evaluation of Novel Furochromene Derivatives

ChemistryOpen, Volume 15, Issue 6, June 2026.
This is the first study on novel furochromene derivatives. A series of novel furochromen derivatives, namely (2E)‐1‐(6‐hydroxy‐4,7‐dimethoxy‐1‐benzofuran‐5‐yl)‐3‐arylprop‐2‐en‐1‐ones 4a–c, were synthesized via the Knoevenagel condensation of 6‐hydroxy‐4,7‐dimethoxybenzofuran‐5‐ylethanone 2 with various aromatic aldehydes.
