A series of bisaryldiketene derivatives were designed and synthesized as a new class of specific G-quadruplex ligands. The ligand-quadruplex interactions were further evaluated by FRET, ITC, and PCR stop assay. In contrast to most of the G-quadruplex ligands reported so far, which comprise an extended aromatic ring, these compounds are neither polycyclic nor macrocyclic, but have a non-aromatic and relative flexible linker between two quinoline moieties enabling the conformation of compounds to be flexible. Our results showed that these bisaryldiketene derivatives could selectively recognize G-quadruplex DNA rather than binding to duplex DNA. Moreover, they showed promising discrimination between different G-quadruplex DNA. The primary binding affinity of ligand M2 for c-myc G-quadruplex DNA was over 200 times larger than that for telomere G-quadruplex DNA.

An efficient electrochemical method for benzylic C(sp3)-H bond oxidation has been developed. A variety of methylarenes, methylheteroarenes, and benzylic (hetero)methylenes could be converted into the desired aryl aldehydes and aryl ketones in moderate to excellent yields in an undivided cell, using O2 as the oxygen source and lutidinium perchlorate as an electrolyte. On the basis of cyclic voltammetry studies, 18O labeling experiments, and radical trapping experiments, a possible single-electron transfer mechanism has been proposed for the electrooxidation reaction.
Imidazopyridine-fused [1,3]diazepinones: modulations of positions 2 to 4 and their impacts on the anti-melanoma activity

A series of 19 novel pyrido-imidazodiazepinones, with modulations of positions 2, 3 and 4 of the diazepine ring were synthesised and screened for their in vitro cytotoxic activities against two melanoma cell lines (A375 and MDA-MB-435) and for their poten
