General description
3-Penten-2-one is volatile compound present in berry fruit of two Aronia melanocarpa genotypes. Urinary 3-penten-2-one is a useful biomarker for increased accumulation of acetaldehyde during abnormal metabolic stress.
Application
3-Penten-2-one was used in the synthesis of the alkaloids (+/-)-senepodine G and (+/-)-cermizine C.
Biochem/physiol Actions
3-Penten-2-one inhibits nitric oxide production and inducible nitric oxide synthase expression via heme oxygenase-1 expression in lipopolysaccharide-activated RAW264.7 macrophages.

Diagnostic profiling of urine for volatile compounds of around 400 patients using headspace solid-phase microextraction (HS-SPME) in alkaline conditions identified 3-penten-2-one (approximately 1 to >6.3 micromol/L) in 26 patients. Five were in barbiturate coma. 3-Penten-2-one, previously of unknown origin, was
