Tissue pH is tightly regulated in vivo, being a sensitive physiological biomarker. Advent of dissolution dynamic nuclear polarization (DNP) and its translation to humans stimulated development of pH-sensitive agents. However, requirements of DNP probes such as biocompatibility, signal sensitivity, and spin-lattice relaxation time (T1) complicate in vivo translation of the agents. Here, we developed a 13C-labeled alanine derivative, [1-13C]-l-alanine ethyl ester, as a viable DNP probe whose chemical shift is sensitive to the
