Researchers Hyperpolarized Acetoacetate Molecules
Scientists achieved significant carbon polarization using a parahydrogen-induced approach.
Updated on Oct. 7, 2026 in Chemistry
Researchers have successfully hyperpolarized [1,3-13C]acetoacetate using a parahydrogen-induced polarization (PHIP) by side arm hydrogenation method. This breakthrough allows for the creation of probes capable of monitoring mitochondrial redox status.
Why it matters
Hyperpolarized acetoacetate provides a powerful tool for detecting the redox status inside mitochondria, offering new insights into metabolic processes. This development supports the creation of advanced beta-ketoacid-derived probes for future biomedical research.
The study recorded 25.5% 1H polarization and 4.1% maximum 13C polarization for P(C-1). Researchers achieved 100% chemical conversion of the propargyl moiety with 80% selectivity toward the allyl [1,3-13C]acetoacetate product.
The details
Using a parahydrogen-induced polarization by side arm hydrogenation approach, the team enabled polarization transfer via a linear magnetic field sweep. The resulting allyl [1,3-13C]acetoacetate undergoes alkaline hydrolysis to convert into enolates, decomposing into hyperpolarized [2-13C]acetone and [13C]carbonate.
