exported by Taiwan. There is no deficiency for thesource of this enzyme. Therefore, the application of bro-melain to catalyze the synthesis of peptides has great poten-tial and economic value.No research effort has ever been made in peptide syn-thesis using bromelain except for catalyzing polymerizationin aqueous solution.

Homologs of D- and L-3-hydroxyacylhexapeptide including compound (I-1c) and its optical isomers (I-1'c, I-2c, I-2'c) were synthesized by condensing the tripeptide subunit with the dipeptide subunit followed by azide coupling of the resulting pentapeptide with D-or L-3-hydroxyacylleucine, and their antibacterial properties were examined. None of the synthetic acylhexapeptides was identical with viscosin in both physical and chemical properties and antituberculous activity.

The chemical model presented here affords a mild and practical methodology for the preparation of C-terminal amides from C-terminal Ser/Thr extended precursors. Further, the oxalamides derived from N-terminal and nonterminal Ser/Thr peptides constitute an entirely novel class of peptide analogues possessing extended planar bis-peptide regions, the study of whose conformational and reactivity profile
此处介绍的化学模型为从 C 端 Ser/Thr 扩展前体制备 C 端酰胺提供了一种温和实用的方法。此外,源自 N 末端和非末端 Ser/Thr 肽的草酰胺构成了一类全新的肽类似物,具有扩展的平面双肽区域,其构象和反应性特征的研究将证明是有趣的
