Hyperpolarization study on remdesivir with its biological reaction monitoring via signal amplification by reversible exchange.

Our experiments indicate hyperpolarized proton signals in the entire structure of remdesivir are obtained due to a long-distance polarization transfer by para -hydrogen. SABRE-based biological real-time reaction monitoring, by using a protein enzyme under mild conditions is carried out. It represents the first successful para -hydrogen based hyperpolarization application in biological reaction monitoring.
