Here, we are developing a group of dDNP polarized tracers based on nicotinamide (NAM). We synthesized 1-<sup>15</sup>N-NAM and 1-<sup>15</sup>N nicotinic acid and hyperpolarized them with dDNP, reaching (13.0±1.9)% <sup>15</sup>N polarization. We found that the lifetime of hyperpolarized 1-<sup>15</sup>N-NAM is strongly field- and pH-dependent, with T<sub>1</sub> being as long as 41 s at a pH of 12 and 1 T while as short as a few seconds at neutral pH and fields below 1 T. The remarkably short 1-<sup>15</sup>N lifetime at low magnetic fields and neutral pH drove us to establish a unique pH neutralization procedure. Using <sup>15</sup>N dDNP and an inexpensive rodent imaging probe designed in-house, we acquired a <sup>15</sup>N MRI of 1-<sup>15</sup>N-NAM (previously hyperpolarized for more than an hour) in less than one second.</p>

Metabolic contrast agent produced from transported solid 13C-glucose hyperpolarized via Dynamic Nuclear Polarization
<p>Magnetic Resonance Imaging combined with hyperpolarized <sup>13</sup>C-labelled metabolic contrast agents produced via dissolution Dynamic Nuclear Polarization can, non-invasively and in real-time, report on tissue specific aberrant metabolism. However, hyperpolarization equipment is expensive, technically demanding and needs to be installed on-site for the end-user. In this work, we provide a robust methodology that allows remote production of the hyperpolarized <sup>13</sup>C-labelled metabolic contrast agents. The methodology, built on photo-induced thermally labile radicals, allows solid sample extraction from the hyperpolarization equipment and several hours’ lifetime of the <sup>13</sup>C-labelled metabolic contrast agents at appropriate storage/transport conditions. Exemplified with [U-<sup>13</sup>C, d<sub>7</sub>]-D-glucose, we remotely produce hyperpolarized <sup>13</sup>C-labelled metabolic contrast agents and generate above 10,000-fold liquid-state Magnetic Resonance signal enhancement at 9.4 T, keeping on-site only a simple dissolution device.</p>
