Fourteen naphthoquinone derivatives (1-14) were designed based on a putative proteasome inhibitor PI-083. These compounds were synthesized and evaluated against A549, DU145, KB, and KBvin tumor cell lines. Six compounds (2, 4, 8, 9, 10, and 13) showed antiproliferative activities comparable to that of PI-083. Among them, compound 8 was confirmed as a 20S proteasome inhibitor in both in vitro and cell-based assays. These findings endorse further optimization efforts based on this structural phenotype to develop potential anticancer drug candidates. (C) 2012 Elsevier Ltd. All rights reserved.

An amino-naphthoquinone ligand and its Co(II), Ni(II), Cu(II) and Zn(II) complexes have been synthesized and characterized using analytical and spectral techniques. The anion sensing behaviour of these receptors is investigated using UV-vis, fluorescence and 1H NMR spectral studies. Electrochemical and DFT computations are also carried out to substantiate the results of spectral studies. The receptors
