ubiquinone-1

Ubiquinone-1 (UQ-1) is an intermediate in the biosynthesis of coenzyme Q, an essential coenzyme in the body's redox reactions, involved in multiple oxidation-reduction processes.

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.

Coenzyme Q6 (Ubiquinone 30), an isoprenylated benzoquinone lipid, plays a pivotal role in respiratory electron transport and acts as a lipid antioxidant. Besides, it possesses antioxidant properties that inhibit the generation of free radicals and prevent oxidative damage [1].

Coenzyme Q8 (Ubiquinone 8) is an isoprenoid quinone isolated from the plasma membrane of wild-type or long-lived qm30 and qm51 clk-1 mutant strains of Cryptomeria cepacia that mediates electron transfer in the aerobic respiratory chain and reduces oxidative stress.
