Explorations of ATP-Binding Cassette Transporters and Apoptosis Signal Pathways of 2-Hydroxyanthraquinone Substituted Cyclotriphosphazenes in MCF-7 and DLD-1 Cell Lines.

Background: As a class with biological properties, such as anti-cancer, anti-bacterial, anti-HIV, and various physical effects, phosphazene derivatives constitute the most striking part of inorganic compounds. Anthraquinones, on the other hand, are a broad family of compounds with a wide variety of biological properties; the biologically active anthraquinones have been used as valuable compounds for biochemical and pharmacological research.

Objective: In this study, we aimed to investigate the effect of the anthraquinone substituted cyclotriphosphazene compounds on apoptosis and drug resistance in MCF-7 and DLD-1 cells.

Chemosensor properties of 7-hydroxycoumarin substituted cyclotriphosphazenes.

The newly synthesized cyclotriphosphazene cored coumarin chemosensors 5, 6, and 7 were successfully characterized by H NMR, P NMR, and MALDI-TOF mass spectrometry. Additionally, the photophysical and metal sensing properties of the targeted compounds were determined by fluorescence spectroscopy in the presence of various metals (Li , Na , K , Cs , Mg , Ca , Ba , Cr , Mn , Fe , Co , Al , Hg , Cu , Zn , Ag , and Cd ) . The fluorescence titration results showed that compounds 5, 6, and 7 could be employed as fluorescent chemosensors for Fe ions with high sensitivity.
