A novel chlorinated coumarin-malononitrile fluorescent probe with three potential reaction sites, which exhibited highly selective, rapid response, low detection limit, and was capable of the simultaneous detection of H2S (λex/em = 515/564 nm) and GSH (λex/em = 430/517 nm), was first proposed. The probe was successfully applied to dual-channel imaging H2S and GSH in MCF-7 cells. © The Royal Society of Chemistry 2016. Source

Two new oxysporone derivatives, pestalrone A (1) and pestalrone B (2), along with two known structurally related compounds 3, 4, were from the fermentation broth of the endophytic plant fungus Pestalotiopsis karstenii isolated from stems of Camellia sasanqua. Their structures and relative configurations were elucidated by extensive spectroscopic analysis and comparison of chemical shifts with related known compounds. Compound 2 exhibited significant activities agains HeLa, HepG2 and U-251 with IC 50 values of 12.6, 31.7 and 5.4 μg/mL, respectively. © 2012 by the authors. Source

Controllable supramolecular chirality based on the self-assembly of the perylene bisimide-carbohydrate conjugates was achieved, which exhibited right-handed chirality under the triazole as the linker, and left-handed chirality with the amide bond as the linker, because of the difference of the chirality transfer induced by the different π⋯π stacking interactions and the additional hydrogen-bonds of the amide bond. © The Royal Society of Chemistry 2015.
