The design, synthesis, and properties of a new gadolinium-based copper-responsive magnetic resonance imaging (MRI) contrast agent is presented. The sensor (GdL1) has high selectivity for copper ions and exhibits a 43% increase in r1 relaxivity (20 MHz) upon binding to 1 equiv of Cu2+ in aqueous buffer. Interestingly, in the presence of physiol. levels of human serum albumin (HSA), the r1 relaxivity is amplified further up to 270%. Addnl. spectroscopic and X-ray absorption spectroscopy (XAS) studies show that Cu2+ is coordinated by two carboxylic acid groups and the single amine group on an appended side chain of GdL1 and forms a ternary complex with HSA (GdL1-Cu2+-HSA). T1-weighted in vivo imaging demonstrates that GdL1 can detect basal, endogenous labile copper(II) ions in living mice. This offers a unique opportunity to explore the role of copper ions in the development and progression of neurol. diseases such as Wilson’s disease.

The author of 《A Simple 3D-Printed Enzyme Reactor Paper Spray Mass Spectrometry Platform for Detecting BuChE Activity in Human Serum》 were Yang, Yanmei; Liu, Huimin; Chen, Zhenzhen; Wu, Tianhong; Jiang, Zhongyao; Tong, Lili; Tang, Bo. And the article was published in Analytical Chemistry (Washington, DC, United States) in 2019. Application In Synthesis of 4-Bromobutanoic acid The author mentioned the following in the article:

To achieve personalized healthcare, a quick, accurate, and high-throughput method to detect disease biomarkers is essential. In the traditional practice, mass spectrometry is one of the most powerful tools and is widely studied. However, the test of human serum usually requires complicated sample pretreatment, tedious operations, and precise condition control, especially for the detection of enzymes as biomarkers. As butyrylcholinesterase (BuChE) has an indicative significance in detecting degenerative disease, liver injury, and organophosphate poisoning, the quick quantification of BuChE is of vital importance to the clinic. In this paper, we report the design and fabrication of a portable 3D-printed enzyme reactor paper spray cartridge (3D ER-PS) with integrated functions: temperature control, enzyme reaction, analyte transfer, and paper spray ionization. Coupled with mass spectrometry, quant. testing of BuChE activity in human serum was realized conveniently and accurately. While it only requires very simple sample preparation, the results from current 3D ER-PS approach are well consistent with those obtained using Ellman’s method. This 3D ER-PS platform not only provides a novel solution for the liquid biopsy of BuChE in clinics but also contributes to the development of quick and targeted medical approaches for analyzing other types of serum biomarker mols. in the field of disease diagnosis. In the experimental materials used by the author, we found 4-Bromobutanoic acid(cas: 2623-87-2Application In Synthesis of 4-Bromobutanoic acid)
