本文报道了新的4-磷酸-d-赤藓酸衍生物的合成方法,即4-磷酸-d-赤藓酸异羟肟酸(1),4-磷酸-d-赤藓酰肼(2)和4-磷酸-d-赤藓酸酰胺(2)。3),并且作为菠菜核糖-5-磷酸异构酶(RPI)催化的5-核糖5-磷酸和5-核糖5-磷酸之间的异构化反应的新型竞争性抑制剂,进行了动力学评价。与唯一已知的RPI抑制剂4-磷酸-d-赤藓酸酯(4,K i = 28μM,K m / K i = 270)相比,异羟肟酸1通过八步合成法从d-阿拉伯糖中获得的,似乎是异构化反应的一种新型有效的高能中间体类似物抑制剂(K i = 29μM,K m / K i = 260)。

comparison of the 1HNMR spectra of the tris-(R)- and the tris-(S)-MPA ester derivatives. An experimental demonstration of this correlation with 24 triols of known absolute configuration and a protocol using two parameters-Deltadelta(RS)(H3) and the difference between Deltadelta RS (H2) and Deltadelta RS (H3) = absolute value (Delta(Deltadelta RS))-for its application to the determination of the absolute
