  Design, synthesis and biological evaluation of novel tripeptidyl epoxyketone derivatives constructed from β-amino acid as proteasome inhibitors

  摘要：

  A series of novel tripeptidyl epoxyketone derivatives constructed from beta-amino acid were designed, synthesized and evaluated as proteasome inhibitors. All target compounds were tested for their proteasome inhibitory activities and selected compounds were tested for their anti-proliferation activities against two multiple myeloma (MM) cell lines RPMI 8226 and NCI-H929. Among them, eleven compounds exhibited proteasome inhibitory rates of more than 50% at the concentration of 1 mu g/mL and nine compounds showed anti-proliferation activities with IC50 values at low micromolar level. Compound 20h displayed the most potent proteasome inhibitory activities (IC50: 0.11 +/- 0.01 mu M) and anti-proliferation activities with IC50 values at 0.23 +/- 0.01 and 0.17 +/- 0.02 mu M against two tested cell lines. Additionally, the poly-ubiquitin accumulation in the western blot analysis supported that proteasome inhibition in a cellular system was induced by compound 20h. All these experimental results confirmed that b-amino acid can be introduced as a building block for the development of proteasome inhibitors. (C) 2014 Elsevier Ltd. All rights reserved.
