membrane potential depolarization, higher ROS values being obtained after coadministration with enzymatic inhibitors. The free chalcone AN3E and its gold(I) complex conjugates located in the cell mitochondria according to confocal microscopy. In addition, complexes 1 and 2 showed in vivo antivascular effects on the chorioallantoic membrane (CAM) of fertilized specific-pathogen-free (SPF) chicken eggs.
(L1–L6) with a D-π-A conjugation system were prepared. The investigations of third-ordernonlinearoptical (NLO) properties indicate that L1–L6 show different degrees of third-order NLO responses. It is surprising that introducing metalions can effectively regulate their third-order NLO properties and even change the type of nonlinear absorption signal from reverse saturable absorption to saturable absorption

and the silver(I) complex [Ag(E)-3}2][SbF6] have been prepared and characterized, including a single crystal X-ray determination of the latter. Surprisingly, no π-stacking between anthracene or pyridine domains is observed in the solid state, and the crystal packing is dominated by Ag⋯F, CHanthracene⋯π-pyridine and CH⋯F interactions. In contrast to (E)-2 and [Ag(E)-2}2]+, neither (E)-3 nor [Ag(E)-3}2]+

brine shrimp lethality assay, and were able to bind to quadruplex DNA. On the other hand, the pyca- and acpy-ligated compounds did not display any lethality and were unable to interact with DNA. The results indicate that the inclusion of a chalcone ligand plays an important role in improving the cytotoxicity and DNA binding capabilities of molybdenum carbonyl compounds.
