  carbamoylmethyl (Cam) esters as acyl donors in the presence of a cysteine protease, papain, immobilized on Celite. Several segment condensations were also achieved generally in high yields without danger of racemization and formation of the secondary-hydrolysis product. Moreover, partial sequences of some bioactive peptides were prepared through segment condensations, and aimed-at peptides were obtained generally

  在固定于硅藻土的半胱氨酸蛋白酶木瓜蛋白酶存在下，通常以高收率合成一系列二肽，其中氨基甲酰基甲基（Cam）酯为酰基供体。通常也以高收率获得数个段的缩合，而没有消旋化和形成二次水解产物的危险。此外，一些生物活性肽的部分序列是通过片段缩合制备的，并且通常以高收率获得了针对性的肽，而没有羧基组分的C-末端残基的外消旋化。因此，在半胱氨酸介导的偶联中再次确定了Cam酯在动力学控制的肽合成中的优越性。 如先前报道的被丝氨酸蛋白酶催化的那些。

  Mechanochemical chemoenzymatic peptide and amide bond formation catalysed by papain was studied by ball milling. Despite the high-energy mixing experienced inside the ball mill, the biocatalyst proved stable and highly efficient to catalyse the formation of α,α- and α,β-dipeptides. This strategy was further extended to the enzymatic acylation of amines by milling, and to the mechanosynthesis of a derivative

  通过球磨研究了木瓜蛋白酶催化的机械化学化学酶促肽和酰胺键的形成。尽管在球磨机内部经历了高能混合，但是生物催化剂被证明是稳定且高效的，以催化α，α-和α，β-二肽的形成。该策略进一步扩展到通过研磨将胺酶促酰化，并扩展到有价值的二肽L-丙氨酰基-L-谷氨酰胺衍生物的机械合成。
• α-Chymotrypsin-catalyzed peptide synthesis in frozen aqueous solution using N-protected amino acid carbamoylmethyl esters as acyl donors

  A kinetically controlled peptide synthesis catalyzed by alpha-chymotrypsin was performed in frozen aqueous solution (ice, -24 degrees C). The yield of the peptide was significantly improved by the use of the carbamoylmethyl (Cam) ester as the acyl donor instead of the conventional ethyl ester. The peptide yield increased up to ca. 90% when N-benzyloxycarbonyl (CBZ)-Phe-OCam and H-Phe-NH2 were used as the acyl donor and nucleophile, respectively. Such an improvement of the peptide yield in ice was also observed in the coupling of other CBZ-amino acid Cam esters as acyl donors. Furthermore, this approach was applied to the synthesis of peptides containing D-amino acids. The peptides such as CBZ-D-Phe-Phe-NH2, CBZ-Phe-D-Phe-NH2 and CBZ-D-Phe-D-Phe-NH2 were also obtained in excellent to moderate yields in ice. A high diastereoselectivity towards the L-L peptide was observed when the racemic amino acid Cam ester was used as the acyl donor in ice. (c) 2005 Elsevier Ltd. All rights reserved.
