Online analytics provides insights into the progress of an ongoing reaction without the need for extensive sampling and offline analysis. In this study, we investigated benchtop NMR as an onlinereactionmonitoring tool for complex enzyme cascade reactions. OnlineNMR was used to monitor a two‐step cascade beginning with an aromatic aldehyde and leading to an aromatic amino alcohol as the final product
在线分析可以深入了解正在进行的反应的进展情况,而无需进行大量采样和离线分析。在这项研究中,我们研究了台式核磁共振作为复杂酶级联反应的在线反应监测工具。在线核磁共振用于监测从芳香醛开始直至最终产物芳香氨基醇的两步级联,应用两种不同的酶和各种共底物和中间体。台式 NMR 能够在缓冲系统中检测单位数 mM 范围内的反应组分浓度,而无需使用氘代溶剂。通过 NMR 测定的浓度与通过 uHPLC 分析的离线样品相关,并显示两种方法之间具有良好的相关性。总之,台式核磁共振被证明是一种灵敏、选择性和可靠的在线反应监测(多步)生物合成方法。未来,在线分析系统(例如所描述的台式核磁共振设备)不仅可以直接监测反应,还可以形成生物催化反应自我调节的基础。
