In order to explore the effective substitutes Trp for Arg on the cellular uptake of oligo-arginine peptides, we designed and synthesized a series of Trp-containing analogues. All synthetic peptides did not show cytotoxicity on Jurkat cells at final concentration of 10μM.[Trp5]- and[Trp6]analogues exhibited moderate cellular uptake(about 75% of octaarginine, R8C), and[Trp6,8]analogue exhibited similar or even slightly increased cellular uptake as compared to R8C. The other synthetic peptides were showed poor cellular uptake(less than 50%). A clear relationship was not observed between hydrophobicity and cellular uptake of the synthetic peptides. These results indicated that oligo-arginine pepitde was relatively tolerant to Trp insertion in the middle position but not in the N-terminal position.}, pages = {47--53}, title = {オリゴアルギニンペプチドの細胞内移行におけるTrp 残基導入の影響}, year = {2014}, yomi = {オノデラ, サトミ and サトウ, ヒロユキ and アンボ, アキヒロ} }
