, p. 100 - 107 (2015)
Four novel salicylaldehyde isonicotinoyl hydrazone derivatives and their corresponding europium ion complexes were synthesized and characterized, while the luminescence properties and the fluorescence quantum yields of the target complexes were investigated. The results indicated that the ligands favored energy transfers to the emitting energy level of europium ion, and four target europium complexes showed the characteristic luminescence of central europium ion. Besides the luminescence intensity of the complex with methoxy group, which possessed the highest fluorescence quantum yield (0.522), was stronger than that of other complexes. Furthermore, the electrochemical properties of the target complexes were further investigated by cyclic voltammetry, the results indicated that the highest occupied molecular orbital (HOMO), lowest unoccupied molecular orbital (LUMO) energy levels and the oxidation potential of the complexes with electron donating group increased, however, that of the complexes with accepting electron group decreased.

A novel series of acridine linked to thioacetamides 9a–o were synthesized and evaluated for their α-glucosidase inhibitory and cytotoxic activities. All the synthesized compounds exhibited excellent α-glucosidase inhibitory activity in the range of IC50 = 80.0 ± 2.0–383.1 ± 2.0 μM against yeast α-glucosidase, when compared to the standard drug acarbose (IC50 = 750.0 ± 1.5 μM). Among the synthesized compounds, 2-((6-chloro-2-methoxyacridin-9-yl)thio)-N-(p-tolyl) acetamide 9b displayed the highest α-glucosidase inhibitory activity (IC50 = 80.0 ± 2.0 μM). The in vitro cytotoxic assay of compounds 9a–o against MCF-7 cell line revealed that only the compounds 9d, 9c, and 9n exhibited cytotoxic activity. Cytotoxic compounds 9d, 9c, and 9n did not show cytotoxic activity against the normal human cell lines HDF. Kinetic study revealed that the most potent compound 9b is a competitive inhibitor with a Ki of 85 μM. Furthermore, the interaction modes of the most potent compounds 9b and 9f with α-glucosidase were evaluated through the molecular docking studies.

Reaction of silyl enol ethers (1a-1f) with N-chlorosuccinimide afforded siloxycarbinyl cations which were trapped by nucleophiles (NaN3 and MeOH); subsequebt rearrangement of the azido products (2a,b,d,e-N3) under reflux in decalin led to anilide derivatives (3a,b,d,e).

, p. 1595 - 1602 (2016)
Novel 6-mercapto-12-phenethyl-quinazolino[3,4-a]quinazolinone derivatives were synthesized through a user-friendly five-step reaction starting from isatoic anhydride. All products were characterized by IR,1H-NMR,13C-NMR spectroscopy, and chemical analysis. All of them were evaluated for their in vitro cytotoxic activity against two cell lines namely MOLT-4 (human lymphoblastic leukemia) and MCF-7 (human breast adenocarcinoma).

Meng, Defen,Liu, Fen,Li, Yingying,Yang, Zehui,Li, Guizhi,Guo, Dongcai
, p. 507 - 514 (2016)
A series of terbium complexes with salicylhydrazide-salicylacylhydrazone derivatives were synthesized and characterized by elemental analysis, IR spectra, UV/vis spectra and thermal analysis. The luminescence and electrochemical properties of the terbium complexes were investigated. The results show that all the target complexes exhibited characteristic emissions of terbium ions and the complex substituted by the chlorine has the strongest luminescence intensity with the highest quantum yield at 0.609. The introduction of donating electron groups could increase the oxidation potential and the highest occupied molecular orbital energy level of the terbium complex; however, the introduction of accepting electron groups gave the opposite result.
