Abstract

Structure-based drug design was used to systematically synthesize PU3-dimers. The cytotoxicity of PU3 dimers 6 against breast cancer cell lines was evaluated, and their potency increased as the length of the bridging linker increased. Among the compounds tested, 6e with a C-20 linker was the most potent and exhibited a 20-to 30-fold increase in activity compared with that of the parent compound 5. Western blot analyses of the cell ...
