An anthracene molecular probe has been synthesised and shown to target mephedrone, a stimulant drug from the cathinone class of new psychoactive substances (NPS). A protocol has been developed to detect mephedrone via the probe using NMR spectroscopy in a

A new series of quinolone-thiazolidinone hybrid molecules 8a-o were prepared. Quinoline compounds were synthesized by Meth-Cohn synthesis and were condensed with 2,3-disubstituted thiazolidinone. These molecules were screened for their anticancer activities against MDA-MB-231 and MCF-7 cell line using MTT assay. Potent compounds were tested for their cytotoxicity on normal HEK 293 cell lines and most potent compound was tested for its cell cycle analysis. Molecular docking and molecular dynamic studies were performed on human N-acetyl transferase (hNAT-1) protein using Schrodinger molecular docking toolkit. Compound 8n emerged as potent with IC50 8.16?μM against MDA-MB-231 cell line followed by 8e with IC50 17.68?μM. Compound 8n arrested cell cycle at G2/M phase and was non-toxic to human normal kidney cell line. The potent compound 8n binds well with human NAT-1 protein with remarkable hydrogen bonding and π–π interactions. Molecular dynamic studies of 8n further confirm the target for these molecules. Target quinolinone-thiazolidinones were found to be new class of compounds targeting hNAT-1 and can serve as new lead compounds in drug discovery.

The reversibility of imine bonds has been exploited to great effect in the field of dynamic covalent chemistry, with applications such as preparation of functional systems, dynamic materials, molecular machines, and covalent organic frameworks. However, acid catalysis is commonly needed for efficient equilibration of imine mixtures. Herein, it is demonstrated that hydrogen bond donors such as thioureas and squaramides can catalyze the equilibration of dynamic imine systems under unprecedentedly mild conditions. Catalysis occurs in a range of solvents and in the presence of many sensitive additives, showing moderate to good rate accelerations for both imine metathesis and transimination with amines, hydrazines, and hydroxylamines. Furthermore, the catalyst proved simple to immobilize, introducing both reusability and extended control of the equilibration process.
