Design and synthesis of naphthoquinone derivatives as antiproliferative agents and 20S proteasome inhibitors
摘要:
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.
Diamine derivatives of quinones, and related compounds, including salts thereof, that modulate the levels of gene expression in cellular systems, such as cancer cells, are disclosed, along with methods for preparing such compounds and derivatives, as well as pharmaceutical compositions containing these compounds and derivatives as active ingredients. Methods of using these as compounds and derivatives as therapeutic agents are also described.
