• Preparation of Phosphoamino Acid Derivatives with Acid Stable<i>O</i>-Phosphono-Protection for the Boc-Mode Solid-Phase Synthesis of Phosphopeptides
  作者：Tateaki Wakamiya、Kunio Saruta、Jun-ichi Yasuoka、Shoichi Kusumoto

  DOI：10.1246/bcsj.68.2699

  日期：1995.9

  Boc-phosphoamino acid derivatives with O-[di(4-nitrobenzyl)- or dicyclohexylphosphono]-protection were prepared for application to the Boc-mode solid-phase synthesis of phosphopeptides. These protecting groups are both stable to TFA, but removable with a combination of trifluoromethanesulfonic acid and methylthiobenzene in TFA. Of these derivatives, Nα-Boc-O-(dicyclohexylphosphono)serine and Nα-Boc-O-(dicyclohexylphosphono)threonine were obtained as crystalline compounds to be favorably utilized as starting materials for solid-phase synthesis using an automated peptide synthesizer. On the other hand, Nα-Boc-O-(dicyclohexylphosphono)tyrosine and all of the O-[di(4-nitrobenzyl)]phosphono derivatives were prepared as crystalline cyclohexylammonium or dicyclohexylammonium salts.

• Synthesis and Biological Evaluation of Tamandarin B Analogues
  作者：Javier Adrio、Carmen Cuevas、Ignacio Manzanares、Madeleine M. Joullié

  DOI：10.1021/ol0530023

  日期：2006.2.1

  [GRAPHICS]The synthesis of two tamandarin B analogues in which the N,O-Me(2)Tyr(5) unit was replaced by N-Me-phenylaianine (N-MePhe(5)) and (S)-2(methylamino)-3-(naphthalen-2-yl)propanoic acid (N-MeNaphth(5)) is described. The choice of the macrocyclization site was crucial to achieve satisfactory macrolactamization. Coupling between norstatine (Nst(1)) and threonine (Thr(6)) afforded only a 15% yield, while lactamization between proline (Pro(4)) and the aromatic moiety could be achieved in 65% yield.
• Synthetic study of phosphopeptides related to heat shock protein HSP27
  作者：Tateaki Wakamiya、Ryusaku Togashi、Takatoshi Nishida、Kunio Saruta、Jun-ichi Yasuoka、Shoichi Kusumoto、Saburo Aimoto、Kumiko Yoshizawa Kumagaye、Kiichiro Nakajima、Kazuhiro Nagata

  DOI：10.1016/s0968-0896(96)00208-8

  日期：1997.1

  Two kinds of phosphoserine-containing peptides related to HSP27 were synthesized by the Boc- or Fmoc-mode solid-phase method based on prephosphorylation strategy. In the case of the Boc strategy, the O-phosphono group of the phosphoserine residue was protected with the cyclopentyl or cyclohexyl group. On the other hand, N-alpha-Fmoc-O-[(benzyloxy)-hydroxyphosphinyl]serine was employed in case of the Fmoc strategy. Consequently, it has become feasible to utilize conventional solid-phase methods for synthesizing any phosphopeptides which are required to elucidate biochemical significance of protein phosphorylation.
