General description

(-)-α-Thujone, a monoterpene ketone found in the essential oil of Thuja occidentalis, shows potent antitumorigenic effect.[1]

Application

  • A six-step total synthesis of α-thujone and d6-α-thujone, enabling facile access to isotopically labelled metabolites: This study presents a concise method for synthesizing α-thujone, useful for creating isotopically labeled derivatives for research purposes (Thamm et al., 2016).
  • Enhancement of CD3AK cell proliferation and killing ability by α-thujone: Investigates α-thujone′s ability to enhance the proliferation and cytotoxic activity of CD3AK cells, suggesting potential immunological applications (Zhou et al., 2016).
  • α-Thujone exhibits an antifungal activity against F. graminearum by inducing oxidative stress, apoptosis, epigenetics alterations and reduced toxin synthesis: Demonstrates the antifungal effects of α-thujone against Fusarium graminearum, which could make it a valuable alternative to traditional fungicides (Teker et al., 2021).

Biochem/physiol Actions

GABAA receptor antagonist.

α-Thujone (1a), a constituent of wormwood, has been suspected to cause adverse psychoactive reactions in addicted drinkers of absinthe. While the content of 1a in absinthe is too low for such effects, at higher doses it can indeed induce seizures
