ピロリン酸トリブチルアンモニウム 化学特性,用途語,生産方法
説明
Tributylammonium pyrophosphate is a phosphorylating reagent used in the synthesis of phosphorylated nucleosides, particularly nucleoside triphosphates used as building blocks for the synthesis of DNA, RNA and sugar nucleotides; as well as a source of cellular energy. Nucleoside triphosphates are typically synthesised by treating free nucleosides with phosphorus oxychloride, then adding tributylammonium pyrophosphate to the reaction intermediate, where the lipophilic tributylammonium salt enhances solubility in organic solvents. Additionally, tributylammonium pyrophosphate was used in the preparation of structurally complex dinucleotide-5’-triphosphates.
使用
Bis(tributylammonium) Pyrophosphate is an phosphorylating reagent used in the synthesis of phosphorylated deoxynucleosides.
Reactant for:
Enzymic synthesis of 3′-deoxy-apio-nucleic acid duplexes
Synthesis of deoxynucleoside S-methylphosphonic acids
Preparation of fluorescent non-nucleotide ATP analog N-methylanthraniloylamideethyl triphosphate
Useful in triphosphate synthesis because of its low water content and high solubility in organic solvents.
製造方法
A solution of tetrasodium pyrophosphate (3.5 g, 7.5 mmol) in water (50 mL) was eluted through a cation exchange resin (BIO-RAD AG 50 W-X8 Resin, 50–100 mesh, hydrogen form) at 4 °C. The eluent with pH of less than 3 (pH paper) was collected directly into a vigorously stirred flask containing tributylamine (2 mL, 8 mmol, 4 °C). The obtained tributylammonium pyrophosphate was dried through repeated rotary evaporation with dry MeOH and then dissolved in dry DMF (10 mL).
一般的な説明
Tributylammonium pyrophosphate is a phosphorylating reagent used in the synthesis of modified dNTPs (deoxynucleoside triphosphates) which are important building blocks for the generation of DNA, RNA, functionalized nucleic acids.
