Because tuberculosis is still a major health threat worldwide, identification of new drug targets is urgently needed. In this study, we considered typeBribose-5-phosphateisomerasefrom as a potential target, and addressed known problems of previous inhibitors in terms of their sensitivity to hydrolysis catalyzed by phosphatase enzymes, which impaired their potential use as drugs. To this end, we
由于结核病仍然是全世界的主要健康威胁,因此迫切需要确定新的药物靶点。在这项研究中,我们将 B 型核糖 5-磷酸异构酶视为潜在靶标,并解决了先前抑制剂对磷酸酶催化水解的敏感性方面的已知问题,这削弱了它们作为药物的潜在用途。为此,我们合成了六种新型拟磷化合物,其设计为底物核糖 5-磷酸和最著名的抑制剂 5-磷酸核糖酸酯的水解稳定类似物。磷酸官能团被膦酰甲基、硫酸酯、磺酰甲基或丙二酸基团取代。评估了对 A 型和 B 型核糖 5-磷酸异构酶的抑制作用,并评估了使用碱性磷酸酶和小牛血清进行水解的稳定性。一种磷酸模拟类似物,5--5-膦酰甲基-核糖酸酯,是第一个抗水解酶的强效、特异性抑制剂。
Readily available carbohydrate-derived imines and amides as chiral ligands for asymmetric catalysis
easy and diastereoseletive strategy for the synthesis of a new tetrahydrofuranic chiral aldehyde and a new tetrahydrofuranic acid derived from d-ribose is reported. These compounds have been shown to be useful starting materials for obtaining a never described before class of iminic- and amidic-carbohydrate-based chiral ligands, endowed with stability to purification on silica flash column and to storage
