The attachment of functional units was achieved by the orthogonal protection of the respective side chain amino functionalities. The nucleobase-functionalized triostin analogs have the potential to recognize double-stranded DNA by hydrogen bonding. The interaction with DNA was investigated by UV spectroscopy and fluorescence intercalator displacement. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim
描述了天然产物 Triostin A 的全合成,其中 N-甲基化缩肽支架是通过溶液相肽化学构建的,然后是二硫化物形成和大环化。最后,连接喹喔啉以提供 DNA 双嵌入剂。Triostin A 的类似物是通过用嘧啶或嘌呤识别单元对环状缩酚肽进行连续功能化而获得的。功能单元的连接是通过相应侧链氨基官能团的正交保护来实现的。核碱基功能化的 Triostin 类似物具有通过氢键识别双链 DNA 的潜力。通过紫外光谱和荧光嵌入剂置换研究了与 DNA 的相互作用。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany,
