  Branched Poly(proline) Peptides: An Efficient New Approach to the Synthesis of Repetitive Branched Peptides

  摘要：

  Proline is unique among the twenty genetically coded amino acids in that it contains both a cyclic backbone and a secondary alpha-amino group, These structural features impart unique stereochemical properties on proline. Poly(proline) oligomers exist in two distinct conformations in solution. In organic solvents they tend to adopt a conformation known as poly(proline) I (PPI), whereas in aqueous solvents they tend to adopt a different conformation known as poly(proline) II (PPII). We report here a new family of branched poly(proline) peptides. After a careful study of the different approaches, an efficient protocol for the synthesis of this kind of peptide has been established. cis-4-Amino-L-proline was mainly used as a branching unit in order to minimize its effects on the conformation of the rest of the molecule. The synthetic strategy employed was based on a convergent solid-phase peptide synthesis methodology that gave crude peptides that were easy to purify. This approach provides a new method for the synthesis of other repetitive branched peptides, minimizing not only synthetic difficulties but also purification problems.

  基于聚脯氨酸螺旋的肽树状聚合物

  摘要：

  我们提出了一个基于聚脯氨酸螺旋和 cis-4-amino-L-proline 作为分支单位的新肽树枝状聚合物家族。树枝状聚合物是通过收敛固相肽合成方法合成的。聚脯氨酸 I 型螺旋和聚脯氨酸 II 型螺旋之间的构象转变是通过圆二色性观察到的具有超过 14 个脯氨酸残基的支链聚脯氨酸结构单元和由此产生的树枝状聚合物。发现线性和树突状聚脯氨酸都被大鼠肾细胞积极内化。初步结果表明，抗生素环丙沙星在 99.5% 丙醇中与支链聚脯氨酸形成复合物。
