Abstract:
We have evaluated the effects of microwave irradiation on the solid-phase synthesis of B-peptides. Sequences designed to adopt the 14-helix, especially those containing the structure – promoting residue trans-2-aminocyclohexanecarboxylix acid (ACHC), suffer from poor synthetic efficiency under standard SPPS conditions. A comparision of microwaveconventional heating shows that both provide excellent synthetic results for shorter sequences; however, we identify a clear benefit from microwave irradiation for longer B-peptides.
應用微波輻射合成14-Helicalβ-Peptides
摘要:
我們已經(jīng)評估微波輻射對固相合成B-peptides的影響。在標準SPPS條件下, 序列用作吸納14-螺旋(14-Helix)是存在非常低的合成效率,尤其是那些含有trans-2-aminocyclohexanecarboxylix acid (ACHC) 殘余物的結(jié)構(gòu)。比較微波加熱和常規(guī)加熱表明,兩者都能為合成短序列多肽提供的綜合成果;但是,我們確定微波輻射也能夠為合成較長的乙肽(β-Peptides) 提供的綜合成果。微波合成。
