Conventional Vaccine

Current highly effective conventional vaccine to halt the spread of bird flu has not been invented yet because of susceptiblemutation of influenza virus. In spite of undergoing mutation which causes the amino acid sequence change, influenzaviruses maintain conservation at ectodomain of M2 protein, especially M2e(2-16) (SLLTEVETPIRNEW). The use ofconserved epitope M2e(2-16) in epitope-based vaccine potentially produces universal influenza vaccine. In designingepitope-based vaccine, the M2e(2-16) needs to be coupled with T helper epitope, P25, which is subsequently mentioned asM2e(2-16)-K-P25 (SLLTEVETPIRNEWGKKKL IPNASLIENCTKAEL). The M2e(2-16)-K-P25 was synthesized usingconvergent solid phase peptide synthesis strategy because of the size of the sequence. In this strategy, four peptideprecursors of M2e(2-16)-K-P25; SLLTEVETP (F1), IRNEWGK (F2), KLIPNASLI (F3), and ENCTKAEL (F4); were synthesizedin advance. After the precursors ready, coupling reaction was performed to obtain M2e(2-16)-K-P25. In the previousresearch, F3 has been obtained in high purity through Fmoc/tBu solid phase peptide synthesis method. In this conductedresearch, the three remaining precursors; F1, F2, and F4; were synthesized by the same method. Each peptide was analysedby thin layer chromatography, HPLC, and mass spectroscopy methods. F1, F2 and F4 were successfully synthesized andeach of them was detected at 1490.0, 1874.8 and 1881.9 amu, respectively. However, F1 was not possible to purify becauseof its insolubility in various solvents.

We describe a method to protect the sensitive stereochemistry of the thioamide—in analogy to the protection of the functional groups of amino acid side chains—in order to preserve the thioamide moiety during peptide elongation.<br>

Routine Production

In the years since the publication of Atherton and Sheppard's volume, the technique of Fmoc solid-phase peptide synthesis has matured considerably and is now the standard approach for the routine production of peptides. The basic problems outstanding at the time of publication of this earlier work have now been, for the most part, solved. As a result, innovators in the field have focussed their efforts to develop methodologies and chemistry for the synthesis of more complex structures. The focus of this new volume is much broader, and covers not only the essential procedures for the production of linear peptides but also more advanced techniques for preparing cyclic, side-chain modified, phospho- and glycopeptides. Many other methods also deserving attention have been included: convergent peptide synthesis; peptide-protein conjugation; chemoselective ligation; and chemoselective purification. The difficult preparation of cysteine and methionine-containing peptides is also covered, as well as methods for overcoming aggregation during peptide chain assembly and a survey of available automated instrumentation.

Fmoc Strategy

Several dendrimers possessing multiple copies of peptides and glycopeptides belonging to the MUC1 eicosapeptide tandem repeat sequence have been prepared. Fmoc-strategy solid-phase peptide synthesis was used to construct the peptides and glycopeptides, which were conjugated to suitably functionalized dendrimer cores using the copper-catalyzed azide-alkyne cycloaddition reaction to produce multivalent peptide and glycopeptide dendrimers.
