General description

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

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).
