A series of conformationally-restrained analogues of 1,3-bisphospho-D-glyceric acid (1,3-BPG) 1 has been synthesised for use as inhibitors of 3-PGK (E.C. 2.7.2.3). These compounds have non-scissile phosphonate linkages and also incorporate α-halogen substituents to make them isopolar and isosteric mimics of the natural substrate. A monocyclic aryl core between the two phosphoryl centres provides both
合成了一系列1,3-双磷酸D-甘油酸(1,3-BPG)1的构象限制类似物以用作抑制剂3-PGK(EC 2.7.2.3)。这些化合物具有非断裂性的膦酸酯键,并且还掺入了α-卤素取代基,使它们成为天然底物的等极性和等规模拟物。单环芳基两个磷酰基中心之间的核提供了连接这些部分和基因座的刚性框架,以供进一步取代。这些化合物针对人类3-PGK进行了测试,发现具有良好的竞争性抑制剂。α-氟的膦酸将对酶的亲和力提高到亚微摩尔范围。IC 50数据与p K a 3和p K a 4值的相关性表明,磷酰基的酸度对蛋白质 捆绑。
