Application


  • RIFM fragrance ingredient safety assessment, 4-hydroxybutanoic acid lactone, CAS Registry Number 96-48-0.: A comprehensive safety assessment of 4-hydroxybutanoic acid lactone as a fragrance ingredient, evaluating its toxicological profile and safe usage levels (Api et al., 2019).

Biochem/physiol Actions

Precursor of γ-hydroxybutyric acid (GHB). It blocks dopamine release by blocking impulse flow in dopaminergic neurons. Pretreatment with γ-butyrolactone allows detection of autoreceptor-induced dopamine release.

C75, a known inhibitor of fatty acid synthase is postulated to cause significant weight loss through decreased hypothalamic neuropeptide Y (NPY) production. Peripherally, C75, an alpha-methylene-gamma-butyrolactone, reduces adipose tissue and fatty liver, despite high levels of malonyl-CoA. To investigate this
