Coenzyme Q0 (CoQ0), a potent, orally active ubiquinone compound derived from Antrodia cinnamomea, induces apoptosis and autophagy. It suppresses HER-2/AKT/mTOR signaling, enhancing apoptosis and autophagy mechanisms. Additionally, Coenzyme Q0 regulates NFκB/AP-1 activation and promotes Nrf2 stabilization, contributing to the attenuation of inflammation and redox imbalance. It also exhibits anti-angiogenic activity by downregulating MMP-9/NF-κB and upregulating HO-1 signaling.

The branches of Kielmeyera by n-hexane isolation of 3,4-Dihydroxy-2-methoxyxanthone, showed moderate to low activity against the tested MRSA strains.[1]
