13C-hyperpolarized carboxylates, such as pyruvate and acetate, are emerging mol. contrast agents for magnetic resonance imaging (MRI) visualization of various diseases, including cancer. Here, we present a systematic study of 1H and 13C parahydrogen-induced polarization of acetate and pyruvate esters with Et, Pr, and allyl alc. moieties. It was found that allyl pyruvate is the most efficiently hyperpolarized compound from those under study, yielding 21 and 5.4% polarization of 1H and 13C nuclei, resp., in CD3OD solutions Allyl pyruvate and Et acetate were also hyperpolarized in the aqueous phase using homogeneous hydrogenation with parahydrogen over a water-soluble rhodium catalyst. 13C polarization values of 0.82 and 2.1% were obtained for allyl pyruvate and Et acetate, resp. 13C-hyperpolarized methanolic and aqueous solutions of allyl pyruvate and Et acetate were employed for in vitro MRI visualization, demonstrating the prospects for translation of the presented approach to biomedical in vivo studies.
The article 《Parahydrogen-Induced Polarization of 1-13C-Acetates and 1-13C-Pyruvates Using Sidearm Hydrogenation of Vinyl, Allyl, and Propargyl Esters》 also mentions many details about this compound(36620-11-8)COA of Formula: C14H8BF4Rh, you can pay attention to it, because details determine success or failure
