Total synthesis of callipeltins B and M, peptidyl cytotoxic agents isolated from marine sponges, by the combination of Fmoc solid-phase peptide synthesis and cyclization and global deprotection in the solution phase is described. Eight amino acids, including several unusual amino acids, were assembled on a solid support, and effective TFA-mediated deprotection was employed to reach callipeltin M. Callipeltin
描述了通过Fmoc固相肽合成和环化以及在溶液相中整体脱保护的组合,从海洋海绵中分离出的Callipeltins B和M(肽基细胞毒剂)的总合成。八个氨基酸,包括一些不寻常的氨基酸,被组装在固体载体上,并且采用有效的TFA介导的脱保护达到callipeltin M. Callipeltin乙经由的侧链之间的macrolactonization被完成d -一个苏氨酸和C-被保护的卡培尔丁M的末端羧酸。
