BCX-1777, a novel inhibitor of the enzyme purine nucleoside phosphorylase, mimics the charged ribosyl oxocarbenium ion formed during the transition state of the enzyme-catalyzed CN bond cleavage of nucleosides. BCX-1777 is a slow-onset, tight-binding inhibitor with a Ki* of 23 pM and is one of the most potent inhibitors known for the enzyme. In support of our BCX-1777 program, a mass spectrometric assay has been developed utilizing 5′-[2H]-BCX-1777 as an internal standard. The synthesis of 5′-[2H]-BCX-1777 is described in this report.

BCX-1777是一种新型的嘌呤核苷磷酸酶抑制剂,它模拟了在酶催化核苷的CN键断裂的过渡态中形成的带电核糖基氧代碳离子。BCX-1777是一种缓慢起效的紧密结合抑制剂,Ki*为23 pM,是已知该酶最有效的抑制剂之一。为了支持我们的BCX-1777项目,我们开发了一种质谱分析方法,利用5′-[2H]-BCX-1777作为内标。本报告描述了5′-[2H]-BCX-1777的合成。版权所有 © 2002 John Wiley & Sons, Ltd.
