BD-AcAc 2 (Ketone Ester) is a ketone monoester and can be used as a source of oral nutritional ketones. BD-AcAc 2 can elevate plasma levels of acetoacetate and β-hydroxybutyrate, blood Na+, blood glucose levels and blood creatinine levels after oral administration in mice. BD-AcAc 2 can partly prevent muscle weakness in septic mice. BD-AcAc 2 exhibits potential to improve endurance and exercise performance in animal body. BD-AcAc 2 can also be used to research diabetes or Parkinson's disease.

BD-AcAc(2) would delay CNS-OT seizures in rats breathing hyperbaric oxygen (HBO(2)). Adult male rats (n = 60) were implanted with radiotelemetry units to measure electroencephalogram (EEG). One week postsurgery, rats were administered a single oral dose of BD-AcAc(2), 1,3-butanediol (BD), or water 30 min before being placed into a hyperbaric chamber and pressurized to 5 atmospheres absolute (ATA) O2 [1]. Beginning at a presymptomatic age, 2 groups of male 3xTgAD mice were fed a diet containing a physiological enantiomeric precursor of ketone bodies (KET) or an isocaloric carbohydrate diet. The results of behavioral tests performed at 4 and 7 months after diet initiation revealed that KET-fed mice exhibited significantly less anxiety in 2 different tests. 3xTgAD mice on the KET diet also exhibited significant, albeit relatively subtle, improvements in performance on learning and memory tests. Immunohistochemical analyses revealed that KET-fed mice exhibited decreased Aβ deposition in the subiculum, CA1, and CA3 regions of the hippocampus, and the amygdala [2].
