氟磷酸核苷酸类似物的合成及其表征作为19 F NMR研究的工具
摘要:
为了拓宽基于19 F核苷酸标记的现有方法的范围,我们开发了一种新的合成方法,用于合成在(低聚)磷酸部分末端含有O到F取代的氟磷酸(低聚)核苷酸类似物,并将其评估为用于19 F NMR研究的工具。我们采用了基于磷咪唑化物化学方法的三种有效而全面的合成方法,并以四正丁基氟化铵,氟一磷酸或氟代磷酸咪唑啉作为氟源,我们制备了30多种含氟磷酸盐的核苷酸,其碱基类型不同(A,G,C,U,7米G),磷酸盐链长(从单链到四链)和其他磷酸盐修饰基团(硫代,硼烷,亚氨基,亚甲基)的存在。使用氟代磷酸咪唑啉酯作为5'-磷酸化寡核苷酸的氟代磷酸化试剂,我们还合成了寡核苷酸5'-(2-氟二磷酸酯),其可能可用作19 F NMR杂交探针。化合物经19 F NMR表征,评估为19F NMR分子探针。我们发现氟磷酸核苷酸类似物可用于监测具有各种特异性和金属离子要求的酶的活性,包括人DcpS酶,一种治疗脊髓性肌萎缩的靶标。

Compounds which inhibit microbial growth or attenuate the virulence of pathogen microorganisms. Compounds of the invention inhibit UDP-galactopyranose mutase (UGM) and have activity as inhibitors of microbial growth of microorganisms which contain this enzyme and particularly those microorganisms in which this enzyme is responsible for the incorporation of galactofuranose residues, particularly for uridine 5'-diphosphate (UDP) galactopyranose mutase. Compounds of the invention inhibit UDP- galactopyranose mutase (UGM) and have activity to attenuate virulence of pathogenic microorganisms, including mycobacteria.

Thirteen nucleoside5′-triphosphates (NTPs) and their β,γ-bridging oxygen-modified analogs (β,γ-CX2-NTPs, X = H, F, Cl, and Br) have been efficiently synthesized from nucleoside5′-phosphoropiperidates with 4,5-dicyanoimidazole as the activator. A high-yielding and chromatography-free protocol for the preparation of both natural and base-modified nucleoside5′-phosphoropiperidates from the corresponding
We describe an efficient and scalable procedure for the chemical synthesis of nucleoside5′-phosphosulfates (NPS) from nucleoside5′-phosphorimidazolides and sulfate bis(tributylammonium) salt. Using this method we obtained various NPS with yields ranging from 70–90%, including adenosine 5′-phosphosulfate (APS) and 2′,3′-cyclic precursor of 3′-phosphoadenosine 5′-phosphosulfate (PAPS), which are the
