  开发肽环氧基酮作为选择性免疫蛋白酶体抑制剂

  摘要：

  设计、合成和评估了一系列具有不同N帽和 P3 构型的环氧酮类似物。我们发现P3中的D -Ala 对于β 5i 选择性超过β 5c至关重要。值得注意的是，在 P3 具有D-构型的化合物20j（β 5i IC 50  = 26.0 nM，25 倍选择性）和20l（β 5i IC 50 = 25.1 nM，24 倍选择性）是最具选择性的抑制剂。虽然20j和20l仅对 RPMI-8226 和 MM.1S 细胞系显示出中等的抗增殖活性，根据我们的实验，这表明单独抑制β 5i 不足以发挥抗癌作用，可能依赖于β 1i的互补抑制，β 5c 和β 5i。这些数据进一步增加了我们对血液系统恶性肿瘤中免疫蛋白酶体抑制剂的理解。

  Design, synthesis and biological evaluation of novel non-covalent piperidine-containing peptidyl proteasome inhibitors

  摘要：

  A series of novel non-covalent piperidine-containing dipeptidyl derivatives were designed, synthesized and evaluated as proteasome inhibitors. All target compounds were tested for their proteasome chymotrypsin-like inhibitory activities, and selected derivatives were evaluated for the anti-proliferation activities against two multiple myeloma (MM) cell lines RPMI 8226 and MM-1S. Among all of these compounds, eight exhibited significant proteasome inhibitory activities with IC50 less than 20 nM, and four are more potent than the positive control Carfilzomib. Compound 28 displayed the most potent proteasome inhibitory activity (IC50: 1.4 +/- 0.1 nM) and cytotoxicities with IC50 values at 13.9 +/- 1.8 nM and 9.5 +/- 0.5 nM against RPMI 8226 and MM-1S, respectively. Additionally, the ex vivo blood cell proteasome inhibitory activities of compounds 24 and 27-29 demonstrated that the enzymatic metabolism in the whole blood could be well tolerated. All these experiments confirmed that the piperidine-containing non-covalent proteasome inhibitors are potential leads for exploring new anti-cancer drugs. (C) 2016 Elsevier Ltd. All rights reserved.

  A series of novel piperazine or piperidine-containing non-covalent peptidyl derivatives possessing a neopentyl-asparagine residue were designed, synthesized and evaluated as proteasome inhibitors. All target compounds were screened for their 20S proteasome chymotrypsin-like inhibitory activities, and 15 ones displayed more potent activities than carfilzomib with IC50 values lower than 10 nM.

  The potential of specific proteasome inhibitors to act as anti-cancer agents has attracted intensive investigations. The proteasome can be covalently inhibited by epoxyketone derivatives via a two-step reaction. Several computational approaches have been developed to mimic the covalent binding event. Compound 1 composed of a six-membered heterocyclic ring was designed by using covalent docking. With a possible different binding mode from the clinical compound Carfilzomib, it occupied the 55 pocket of 20S proteasome and showed favorable inhibitory activity. Subsequently optimization and evaluation were taken place. Among these compounds, 11h demonstrated extraordinary in vitro inhibitory activity and selectivity, and good in vivo proteasome inhibitory activity, a favorable pharmacokinetic profile and xenograft tumor inhibition. The possible binding pattern of compound 11h against proteasome was further fully explored via calculations, providing a theoretical basis for finding potent proteasome inhibitors.
