  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.

  conjugates (ADCs) represent a new dimension of anticancer chemotherapeutics, with warheads to date generally involving either antitubulin or DNA-directed agents to achieve low-to sub-nanomolar potency. However, other potent cytotoxins working by different pharmacological mechanisms are under investigation, such as α,β-epoxyketone based proteasome inhibitors. These proteasome active agents are an emerging

  (iP)-targeting linear peptide epoxyketones improve cognitive function in mouse models of Alzheimer’s disease (AD) in a manner independent of amyloid β. However, these compounds’ clinical prospect for AD is limited due to potential issues, such as poor brain penetration and metabolic instability. Here, we report the development of iP-selective macrocyclic peptide epoxyketones prepared by a ring-closing

  此前，我们报道了免疫蛋白酶体（iP）靶向的线性肽环氧酮以独立于β淀粉样蛋白的方式改善阿尔茨海默病（AD）小鼠模型的认知功能。然而，由于大脑渗透性差和代谢不稳定等潜在问题，这些化合物治疗 AD 的临床前景受到限制。在这里，我们报道了 iP 选择性大环肽环氧酮的开发，该酮是通过连接在线性对应物的 P2 和 P3/P4 位置上的两个末端烯烃之间的闭环复分解反应制备的。我们发现，先导大环化合物 DB-60 ( 20 ) 能有效抑制 ABCB1 过表达细胞中 iP 的催化活性 (IC 50 : 105 nM)，并且具有优于其线性对应物的代谢稳定性。 DB-60 ( 20 ) 还降低了 Tg2576 小鼠的血清 IL-1α 水平并改善了认知缺陷。这些结果共同表明，大环肽环氧酮比其线性对应物具有改善的中枢神经系统药物特性，并且作为 AD 候选药物具有广阔的潜力。
