Intermediate compounds are disclosed for making incretin analogs, or pharmaceutically acceptable salts thereof. In addition, methods are disclosed for making incretin analogs by coupling from two to four of the intermediate compounds herein via hybrid liquid solid phase synthesis or native chemical ligation.
showed good to strong antiproliferative activity (IC50 <10 nM) for different cancer cell lines. Finally, the four conjugates were exposed to two cancer cell lines [cervix carcinoma, KB‐3‐1 (FR+) and lung carcinoma, A‐459 (FR−)], the latter devoid of the membrane‐bound folic acid receptor (FR−). All four conjugates showed strong antiproliferative activity for the FR+ cancer cell line but were inactive
据报道,四种新的肿瘤特异性叶酸/阿米托星偶联物的获得依赖于基于突变合成和半合成相结合的合成策略。分别通过突变合成或改良的发酵方案制备了两种溴化安那托霉素衍生物,它们是在Stille条件下半合成引入烯丙基胺连接基的起点。一系列标准的偶联步骤将蝶酸/谷氨酸/半胱氨酸单元引入到修饰的安托霉素中。所有新的衍生物,包括那些预期在叶酸/阿米托星共轭物内化到癌细胞中以及二硫键还原还原后产生的衍生物,都显示出良好的至强的抗增殖活性(IC 50 <10 n M)用于不同的癌细胞系。最后,将四种结合物暴露于两种癌细胞系中[子宫颈癌,KB-3-1(FR +)和肺癌,A-459(FR-)],后者没有膜结合叶酸受体(FR -)。所有四种结合物均对FR +癌细胞系表现出强大的抗增殖活性,但对FR-细胞系无活性。所追求的合成策略是基于突变合成和半合成的组合,并被证明对于获取难以通过全合成制备的新的安索霉素衍生物具有强大的作用。
Peptide inhibitors of the Keap1–Nrf2 protein–protein interaction with improved binding and cellular activity
Inhibitors of the Keap1âNrf2 proteinâprotein interaction (PPI) have been proposed as potential anti-inflammatory and cancer chemopreventive agents. Such compounds have the potential to increase the intracellular concentrations of Nrf2 in a reversible manner and consequently increase the expression of a battery of gene products with antioxidant response elements (AREs) in their promoter region. In this manuscript we describe the development of peptide inhibitors with modified C- and N-termini and reduced overall charge. The activity of the compounds in inhibiting the PPI and in cellular assays of Nrf2 function are described. Compound 10 has potent activity (IC50 = 22 nM) in a cell-free fluorescence polarisation assay and induced the expression of Nrf2 dependent gene products in cells, suggesting that it has potential as a lead molecule for the development of peptidomimetic inhibitors.
Keap1-Nrf2蛋白-蛋白相互作用(PPI)抑制剂被认为是潜在的抗炎和癌症化学预防药物。这类化合物有可能以可逆的方式增加细胞内 Nrf2 的浓度,从而增加启动子区含有抗氧化反应元件(AREs)的一系列基因产物的表达。在这篇手稿中,我们介绍了经过修饰的 C 端和 N 端以及整体电荷减少的多肽抑制剂的开发情况。文中描述了这些化合物在抑制 PPI 和细胞检测 Nrf2 功能方面的活性。化合物 10 在无细胞荧光偏振试验中具有强效活性(IC50 = 22 nM),并能诱导细胞中 Nrf2 依赖性基因产物的表达,这表明它有潜力成为开发拟肽抑制剂的先导分子。
