  • Anticancer compound. Inhibits TNF-α-induced and B-16 melanoma-induced angiogenesis.
  • Induces apoptosis and RIP1- and RIP3-dependent necroptosis in several cancer cells. Circumvents cancer antidrug resistance through the necroptosis pathway.
  • Proteasome inhibitor. Autophagy inducer.
  • Topoisomerase I inhibitor.
  • Inhibits glycolysis in cancer cells by inhibiting tumor-specific pyruvate kinase M2 (PKM2).
  • Anti-inflammatory compound. Inhibits leukocyte migration, downregulates chemokine receptor expression, and inhibits HIV-1 replication.
  • Inhibits the activation of NLRP3 and AIM2 inflammasome. Shown to directly target caspase-1 and as a inhibitor of PKM2 to block PKM2-mediated glycolysis that promotes inflammasome activation by modulating EIF2AK2 phosphorylation in macrophages.
  • Antioxidant. Free radical scavenger.
  • Directly inhibits nitric oxide synthase (NOS).
  • Regulator of systemic glucose tolerance, energy balance and adiposity/obesity. Adipogenesis inhibitor. Shown to inhibit fat accumulation in adipocytes.
  • Antibacterial and antifungal agent.
  • Shown to potentially inhibit the 33.8-kDa Main Protease (Mpro)/3C-like Protease of SARS-CoV-2, consequently inhibiting viral transcription and replication and possibly inhibiting spread of COVID-19.
