参考标题:Total Synthesis Of Quinaldopeptin And Its Analogues 作者:Satoshi Ichikawa,Takuya Okamura,Akira Matsuda |发布日期:2013.12.20 摘要:The First Total Synthesis Of Quinaldopeptin (1) Was Accomplished. Our Approach To The Synthesis Of 1 Includes The Solid-Phase Peptide Synthesis Of The Linear Decapeptide 4 Followed By Macrocyclization And Introduction Of The Quinoline Chromophores 2 At A Late Stage Of The Synthesis. As For The Preparation Of 4, A Fragment Coupling Approach Was Applied Considering The C2 Symmetrical Structure Of 1. Chromophore Analogues 22 And 23 And Desmethyl Analogue 27 Were Also Prepared In A Manner Similar To The Synthesis Of 1. Synthetic 1 Exhibits A Strong Cytotoxicity With The Ic50 Value Of 3.2 Nm. On The Other Hand, The Activity Of 23 And 27 Was Largely Reduced.
