翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Thermolabile protecting groups ： ウィキペディア英語版 Thermolabile protecting groups Thermolabile Protecting Groups (TPGs) are applied in chemical synthesis when mild deprotection conditions are required. Their removal merely consists of increasing temperature, which leads to deprotection of the protected sensitive part of a molecule. The deprotection mechanism has been proven only for several TPGs. Most of these groups are removed on the basis of intramolecular cyclization depending either on nucleophilicity or configuration. TPGs are characterized by a different half-life after increasing temperature by 70 °C. The shortest deprotection time with high stability in lower temperatures has been found for 2-pyridyl TPGs that are applied to protect a hydroxyl group or a phosphate centre. For these groups stabilization systems have been developed depending on the protected part of a molecule: for a phosphate centre it is the "click-clack" approach, and for a hydroxyl group – the "chemical switch" concept. TPGs are applied as an element that increases the specificity of starters in PCR; they may also be used in microarray construction. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thermolabile protecting groups」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
