  摘要：

  Two novel handles for peptide amide preparation under mild conditions were developed for use in highly efficient solid-phase peptide synthesis. These handles, 5-{[(R,S)-5-[(9-fluorenylmethoxy-carbonyl)amino]-10,11-dihydrodibenzo[a,d]cyclohepten-2-yl]oxy}valeric acid (CHA) and 5-{[(R,S)-5-[(9-fluorenylmethoxycarbonyl)amino]dibenzo[a,d]cyclohepten-2-yl]oxy}valeric acid (CHE), were attached to the solid support and were used for syntheses of peptides having a C-terminal amide by the fluorenylmethoxycarbonyl strategy. The cleavability of CHA and CHE was determined and compared with the that commercially available amide handles. CHA and CHE handles can be rapidly cleaved from the polymer support without significant side reactions using lower acid concentrations than those required for conventional handles. As CHA can be easily synthesized in large amounts, it is suitable for peptide amide preparation for pharmaceuticals. As CHE can be cleaved at very low concentrations of acid, it is especially suitable for preparing side chain-protected peptide amides: Several brain-gut peptides having a C-terminal amide were synthesized in high yield and high purity with these novel handles.

  The present invention is directed to a compound represented by the following formula (I), and a linker for peptide synthesis using the above compound. When the linker of the present invention is used for the solid-phase peptide synthesis, it is possible to synthesize those peptides which are sensitive to acid and difficult to synthesize by conventional methods. Also, side reactions can be prevented, and the desired product is produced at a high purity because cleavage can be achieved under milder conditions or in shorter times. In other words, efficient peptide synthesis is possible.

  本发明涉及下式 (I) 所代表的化合物、 以及使用上述化合物进行多肽合成的连接剂。当本发明的连接剂用于固相肽合成时，可以合成那些对酸敏感和难以用传统方法合成的肽。此外，由于可以在较温和的条件下或在较短的时间内实现裂解，因此可以防止副反应，并生产出高纯度的所需产品。换句话说，高效的多肽合成成为可能。
