In a series of indolo[3,2‐b]carbazoles (X‐ICZ‐p1; X = F, Cl, Br), the afterglow properties are shaped by modulating intersystem crossing (ISC/rISC) and phosphorescence rates. F/Cl‐ICZ‐p1 systems show moderate rates, achieving color‐tunable, dual‐mode afterglow in polymethyl methacrylate from persistent thermally activated delayed fluorescence (pTADF ...

A Unique Topoisomerase II Inhibitor with Dose-Affected Anticancer Mechanisms and Less Cardiotoxicity
Type II DNA topoisomerase (topo II) is an essential nuclear enzyme and a well-validated anticancer drug target. Previously, we have carried out several rounds of structural optimizations on our in-house topo II inhibitor E17, which was shown to have ...

Improving the fluorescent probe acridonylalanine through a combination of theory and experiment [PDF]
Acridonylalanine (Acd) is a useful fluorophore for studying proteins by fluorescence spectroscopy, but it can potentially be improved by being made longer wavelength or brighter.

Acridone alkaloids and flavones from the leaves of Citrus reticulata
A new acridone alkaloid, reticarcidone A (1), decorated with an oxygenated isopentenyl group between C-1 and C-2, was isolated from the leaves of Citrus reticulata Blanco, together with nine known acridone alkaloids (2–10) and fifteen flavones compounds (

Unravelling the Functional Diversity of Type III Polyketide Synthases in Fungi
Type III polyketide synthases (T3PKSs) produce diverse compounds of ecological and clinical importance. Here, the activity of 37 fungal T3PKSs was profiled, revealing unexpected products and generating several pharmaceutical precursors. The machine learning model trained on the activity data accurately extrapolates the predictions to other enzymes and ...

Temperature dependent NIR emitting lanthanide-PMO/silica hybrid materials [PDF]
Two materials - a mesoporous silica (MS) and a periodic mesoporous organosilica (PMO) functionalized with dipyridyl-pyridazine (dppz) units were grafted with near-infrared (NIR) emitting lanthanide (Nd3+, Er3+, Yb3+) complexes in an attempt to obtain ...
