Descrição geral

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.

Aplicação

3-Penten-2-one was used in the synthesis of the alkaloids (+/-)-senepodine G and (+/-)-cermizine C.

Ações bioquímicas/fisiológicas

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.
