  Dipeptidyl peptidase-4 inhibitor with β-amino amide scaffold: Synthesis, SAR and biological evaluation

  摘要：

  Inhibitors of dipeptidyl peptidase-4 (DPP4) have been shown to be effective treatments for type 2 diabetes. Several series of beta-amino amide containing piperazine derivatives have been prepared and evaluated as a inhibitor of DPP4. Finally compound 5m was selected for further evaluation.

  探索新的哌嗪或哌啶构建的非共价肽基衍生物作为蛋白酶体抑制剂

  摘要：

  设计，合成和评价了一系列具有新戊基-天冬酰胺残基的新的哌嗪或含哌啶的非共价肽基衍生物，并评价它们为蛋白酶体抑制剂。筛选了所有目标化合物的20S蛋白酶体胰凝乳蛋白酶样抑制活性，其中15种化合物比卡非佐米具有更强的活性，IC 50值低于10 nM。随后，测试了最有效的10种类似物对两种多发性骨髓瘤（MM）细胞系RPMI-8226和MM-1S的细胞毒活性。基于这些实验，进一步评估了所选衍生物的离体和体内血细胞蛋白酶体抑制活性。最有潜力的化合物35（蛋白酶体抑制IC 50：1.2±0.1 nM），具有有效的抗增殖作用（IC 50：RPMI-8226 8.4±0.8 nM； MM-1S：6.3±0.8 nM），离体和体内活性也具有延长的半衰期在血浆中的抗性，这表明通过在肽骨架中构建六元环可提高该系列化合物的酶稳定性。所有的实验都证实了设计概念的正确性，这使得该系列化合物成为探索新的抗MM药物的潜在线索。

  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.

  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. Subsequently
