The nuclear magnetic resonance (NMR) detectability of several TB‐relevant agents have been significantly improved through the use of the parahydrogen‐based hyperpolarization protocol signal amplification by reversible exchange (SABRE) in conjunction with the 2H‐labelling of key sites within their molecular structures and the 2H‐labelling of the magnetization‐transfer catalyst. The T1 relaxation times and polarization levels of these agents are quantified under test conditions to produce a protocol to identify structurally optimized motifs for future detection in MRI.
