  Synthesis of Second-Generation Sansalvamide A Derivatives: Novel Templates as Potential Antitumor Agents

  摘要：

  We report the synthesis of 34 second-generation Sansalvamide A derivatives. San A derivatives have unique anticancer properties and target multiple cancers, including colon, pancreatic, breast, prostate, and melanoma. As novel templates, the derivatives described herein explore the role of stereochemistry, amide bond geometry, transannular hydrogen bonding, and polarity on antitumor potency. Testing the chemotherapeutic activity of these derivatives against multiple cancer cell lines will provide clear structural motifs and identify conformational space that is important for cytotoxicity. The 34 compounds presented are divided into six series, where five series involve the insertion of D-amino acids in conjunction with four structural features at each of the five positions of the macrocycle. The sixth series involves comparison between all L- and all D-amino acid derivatives with N-methyls placed at each position around the macrocyclic core. The four structural features explored in conjunction with D-amino acids include N-methyl amino acids, aromatic amino acids, polar amino acids, and hydrophobic alkyl amino acids.

  异手性三肽的晶体结构和超分子排列

  摘要：

  研究了末端保护的 Boc-Val-Phe-Phe-OMe 的所有可能立体异构体的自组装特性，与阿尔茨海默氏淀粉样蛋白-β (Aβ 18-20 ) 肽具有序列同质性。场发射扫描显微镜（FE-SEM）的形态分析表明，受保护的 VFF 和 vff（小写字母表示d 的一个字母代码）-氨基酸）表现出带状纤维网络，vFF、Vff、VfF和vFf形成棒状结构。尽管 VFf 表现出两种形态（棒状和球形）的混合，但 vfF 主要显示球形结构。单晶 X 射线衍射 (SC-XRD) 表明五个立体异构体形成平行的β-折叠排列。在高阶包装中，Vff、VfF 和 vFf 表现出超分子片状结构，而 VFf 和 vfF 对则表现出螺旋片状排列。所有相应的对映异构体都显示出相同的形态但相反的构象。肽中氨基酸的手性在其超分子排列中起着重要作用。有趣的是，所有自聚集肽都可以与淀粉样蛋白结合染料硫黄素 T 结合。

  by the amino acid adjacent to the benzene core, irrespective of the absolute configuration of the C‐terminal amino acid. In addition, molecular chirality also has a significant influence on the gelation behavior. For the diphenylalanine‐based gelators, the homochiral gelators can be gelled through a conventional heating–cooling process, whereas heterochiral gelators form translucent stable gels under

  尽管已经在各种结构水平上制备了手性纳米结构，但是手性从分子到超分子自组装的转移和扩增仍然令人费解，特别是对于杂手性分子而言。在此，C 2的四个系列设计并合成了具有各种氨基酸序列和不同手性的基于对称二肽的衍生物。实现了分子手性向超分子组装体的转录和扩增。结果表明，超分子手性仅由与苯核心相邻的氨基酸决定，而与C端氨基酸的绝对构型无关。另外，分子手性也对胶凝行为具有重要影响。对于基于二苯丙氨酸的胶凝剂，同手性胶凝剂可以通过常规的加热-冷却过程进行胶凝，而异手性胶凝剂在超声处理下形成半透明的稳定凝胶。外消旋凝胶比纯对映异构体具有更高的机械性能。
• Comprehensive Study of Sansalvamide A Derivatives and their Structure–Activity Relationships against Drug-Resistant Colon Cancer Cell Lines

  We report an extensive structure-activity relationship (SAR) of 62 compounds active against two drug-resistant colon cancer cell lines. Our comprehensive evaluation of two generations of compounds utilizes SAR, NMR, and molecular modeling to evaluate the key 3D features of potent compounds. Of the seven most potent compounds reported here, five are second-generation, emphasizing our ability to incorporate potent features found in the first generation and utilize their structures to design potency into the second generation. These analogs share no structural homology to current colon cancer drugs, are cytotoxic at levels on par with existing drugs treating other cancers, and demonstrate selectivity for drug-resistant colon cancer cell lines over noncancerous cell lines. Thus, we have established sansalvamide A as an excellent lead for treating, multiple drug-resistant colon cancers.

  Utilizing the structure-activity relationship we have developed during the synthesis of the first two generations and mechanism of action studies that point to the interaction of these molecules with the key oncogenic protein Hsp90, we report here the design of 32 new Sansalvamide A derivatives and their synthesis. Our new structures, designed from previously reported potent compounds, were tested for cytotoxicity on the HCT116 colon cancer cell line, and their binding to the biological target was analyzed using computational studies involving blind docking of derivatives using Autodock. Further, we show new evidence that our molecules bind directly to Hsp90 and modulate Hsp90's binding with client proteins. Finally, we demonstrate that we have integrated good ADME properties into a new derivative. Published by Elsevier Ltd.
