  三肽基呋喃酮酮作为人20S蛋白酶体β5亚基选择性抑制剂的设计与合成

  摘要：

  设计合成了一系列以呋喃酮为C末端的三肽蛋白酶体抑制剂。针对β1，β2和β5亚基的生化评估表明，它们选择性地作用于β5亚基，IC 50抑制微摩尔范围内的胰凝乳蛋白酶样（CT-L）活性。配体20S蛋白酶体混合物的LC-MS / MS分析表明，最有效的化合物11m（IC 50 = 0.18μM）对20S蛋白酶体未进行共价修饰。但是，在洗脱分析中发现它以缓慢可逆的方式起作用，并且可逆性远低于MG132，这表明这些三肽呋喃酮与20S蛋白酶体形成可逆共价键的可能性。选择了几种化合物用于针对多种癌细胞系的抗增殖测定，并且化合物11m在所有测试的细胞系中显示出与阳性对照（MG132）相当的效能。此外，大鼠的药代动力学（PK）数据表明11m的行为与临床使用的卡非佐米类似（C max，2007μg/ L； AUC 0-t，680μg / L·h； V ss，0.66 L / kg）。所有这些数据表明11m是一

  Total synthesis of the originally proposed structure of coibamide A, a highly N- and O-methylated cytotoxic marine cyclodepsipeptide, has been accomplished by using a [(4+1)+3+3]-peptide fragment-coupling strategy and careful examination and optimization of the multiple dense N-methylated amide-bond formations. The synthetic sample of the proposed coibamide A could not match the natural product in

  A novel series of pyrrolidine-2-carbonitrile and 4-fluoropyrrolidine-2-carbonitrile derivatives was designed, synthesized, and found to act as dipeptidyl peptidase-4 (DPP-4) inhibitors. From this series of compounds, compound 17a was identified as an efficacious, safe, and selective inhibitor of DPP-4. In vivo studies in ICR and KKAy mice showed that administration of this compound resulted in decreased
