Abstract

Seven phosphorothioate analogs of c-di-GMP (all diastereomers of mono-, di-, and trithiophosphates) were prepared to assess the impact of the thioate substitutions on c-di-GMP polymorphism using 1D (1)H and (31)P NMR, along with 2D NOESY and DOSY, for both the Na(+) and K(+) salts. The K(+) salts display more extensive higher order complex formation than the Na(+) salts, resulting primarily in octamolecular complexes with K(+), but tetramolecular complexes with Na(+). Further, the presence of one or two [S(P)] sulfurs specifically stabilizes anti complexes and/or destabilizes syn complexes, while the presence of two [S(P)] sulfurs promotes extensive aggregation.

摘要

制备了七种环二鸟苷单磷酸(c-di-GMP)的硫代磷酸酯类似物(单硫代、二硫代和三硫代磷酸酯的所有非对映异构体),以使用一维(1)H和(31)P核磁共振,以及二维核Overhauser效应光谱(NOESY)和扩散排序光谱(DOSY)来评估硫代磷酸酯取代对c-di-GMP多态性的影响,研究对象包括钠盐和钾盐。钾盐比钠盐表现出更广泛的高阶复合物形成,主要形成与钾离子的八聚体复合物,但与钠离子形成四聚体复合物。此外,一个或两个[S(P)]硫的存在特异性地稳定了反式复合物和/或破坏了顺式复合物的稳定性,而两个[S(P)]硫的存在促进了广泛的聚集。
