  The present invention has an object of providing a peptide synthesis method using a carrier capable of reversibly repeating the dissolved state and the insolubilized state, wherein the problem of an amino acid active species existing in the reaction system in de-protection reaction can be easily solved. The present invention provides a peptide synthesis method comprising the following steps: a step of condensing an N-Fmoc protected amino acid with a peptide having a C-terminal protected with a carrier which is crystallized according to a change of a composition of a dissolving solvent, in the presence of a condensing agent, to obtain an N-Fmoc-C-carrier protected peptide, a step of adding an alkylamine having 1 to 14 carbon atoms or hydroxyl amine to the reaction system, a step of de-protecting the N-terminal, and a step of changing the composition of the solvent dissolving the C-carrier protected peptide, to crystallize and separate the peptide.

  本发明的目的是提供一种肽合成方法，使用能够可逆地重复溶解状态和不溶解状态的载体，从而可以轻松解决去保护反应中存在的氨基酸活性物种的问题。本发明提供一种肽合成方法，包括以下步骤：将N-Fmoc保护的氨基酸与具有C末端保护的肽在存在缩合剂的情况下与根据溶解溶剂的组成变化结晶的载体进行缩合，以获得N-Fmoc-C-载体保护的肽，向反应体系中加入具有1至14个碳原子的烷基胺或羟胺，去保护N末端，改变溶解C-载体保护的肽的溶剂组成的步骤，结晶并分离肽。

  The present invention provides a photolabile protecting group that can be removed by light irradiation under mild conditions. More specifically, the present invention provides a method comprising protecting a reactive functional group (e.g., a hydroxyl group, amino group, carboxyl group, carbonyl group, phosphodiester group, etc.) by the photolabile protecting group, and then removing the photolabile protecting group simply by light irradiation under neutral conditions. The present invention relates to a compound represented by Formula (3): wherein Ar 1 is an optionally substituted aromatic or heteroaromatic ring, Ar 2 is an optionally substituted aryl or heteroaryl group, X is a leaving group, and n is an integer of 1 or 2; and a method of protecting and deprotecting an amino group etc. using the compound.

  本发明提供了一种可以在温和条件下通过光照射去除的光敏保护基团。更具体地说，本发明提供了一种方法，包括通过光敏保护基团保护一个反应性功能团（例如，羟基、氨基、羧基、酮基、磷二酯基等），然后在中性条件下简单地通过光照射去除光敏保护基团。本发明涉及一种由公式（3）表示的化合物：其中Ar1是可选地取代的芳香或杂芳环，Ar2是可选地取代的芳基或杂芳基团，X是离去基团，n是1或2的整数；以及一种使用该化合物保护和解保护氨基等的方法。

  The present invention is directed compositions for delivery of RNA interference (RNAi) polynucleotides to cells in vivo. The compositions comprise amphipathic membrane active polyamines reversibly modified with enzyme cleavable dipeptide-amidobenzyl-carbonate masking agents. Modification masks membrane activity of the polymer while reversibility provides physiological responsiveness. The reversibly modified polyamines (dynamic polyconjugate or DPC) are further covalently linked to an RNAi polynucleotide or co-administered with a targeted RNAi polynucleotide-targeting molecule conjugate.

  本发明涉及用于将RNA干扰（RNAi）多核苷酸传递至体内细胞的组合物。这些组合物包括与酶可切割二肽-酰胺基苄-碳酸酯掩蔽剂可逆修饰的两性膜活性多胺。修饰掩蔽了聚合物的膜活性，而可逆性提供了生理响应性。可逆修饰的多胺（动态多共轭物或DPC）进一步与RNAi多核苷酸共价连接，或与靶向RNAi多核苷酸的分子结合物共同给药。
