As a result of their increased sensitivity, hyperpolarized (HP) NMR molecular probes can be used to perform time-resolved spectroscopy and imaging in vitro and in vivo. It is, however, challenging to design such probes de novo. Herein, the [1-13C]a-amino acid is reported as a scaffold structure to design HP 13C NMR molecular probes. The [1-13C]a-amino acid can be converted to various HP 13C chemical probes that show sufficient chemical shift change by altering the chemical state of the a nitrogen upon interaction with the target. Several previously reported HP probes could be explained by this design principle. To demonstrate the versatility of this approach, two a-amino-acid-based HP 13C chemical probes, sensitive to pH and Ca2+ ion, were developed and used to detect targets.}, pages = {949--953}, title = {A Strategy to Design Hyperpolarized 13 C Magnetic Resonance Probes Using [1-13 C]α-Amino Acid as a Scaffold Structure}, volume = {12}, year = {2017} }
