生物活性

Coenzyme Q10 is an essential cofactor of the electron transport chain and a potent antioxidant agent.

IC50 & Target

Human Endogenous Metabolite

 

体外研究
(In Vitro)

Coenzyme Q10 is an obligatory member of the respiratory chain in the mitochondria of all cells. Therefore, it is an essential ingredient in the formation of adenosine triphosphate (ATP), the source of energy in most cellular processes. Coenzyme Q10 is located in the mitochondria, lysosomes, and Golgi and plasma membranes, and provides an antioxidant action either by direct reaction with free radicals or by regeneration of tocopherol and ascorbate from their oxidised state[1]. Coenzyme Q10 is a popular dietary supplement because of its recognition by the public as an important nutrient in supporting human health. The rationale for the use of Coenzyme Q10 as a therapeutic agent in several cardiovascular and degenerative neurologic and neuromuscular diseases is based upon its fundamental role in mitochondrial function and cellular bioenergetics[2].

体内研究
(In Vivo)

Because of its hydrophobicity and large molecular weight, absorption of dietary Coenzyme Q10 is slow and limited. In the case of dietary supplements, solubilized Coenzyme Q10 formulations show enhanced bioavailability. The Tmax is around 6 h, with an elimination half-life of about 33 h. The reference intervals for plasma Coenzyme Q10 range from 0.40 to 1.91 mM in healthy subjects. With Coenzyme Q10 supplements there is reasonable correlation between increase in plasma Coenzyme Q10 and ingested dose up to a certain point. Animal data show that Coenzyme Q10 in large doses is taken up by all tissues including heart and brain mitochondria[2]. In 12-month-old rats administration of coenzyme Q10 results in significant increases in cerebral cortex mitochondrial concentrations of coenzyme Q10. Oral administration of coenzyme Q10 markedly attenuates striatal lesions produced by systemic administration of 3-nitropropionic acid and significantly increases life span in a transgenic mouse model of familial amyotrophic lateral sclerosis[3].

Animal Administration
[3]

Rats[3]

The effects of oral administration of coenzyme Q10 on 3-NP-induced striatal lesions are examined in 300- to 350-g rats (n=5-10). Animals receive either rat chow supplemented with coenzyme Q10 at 200 mg/kg or unsupplemented rat chow. After 1 week they are treated with 3-NP at a dose of 10 mgykg i.p. twice a day until either a control or treated animal became symptomatic with hindlimb dystonia, and then sacrificed in pairs[3].

Mice[3]

To determine whether coenzyme Q10 exerts neuroprotective effects in a transgenic mouse model of a human neurodegenerative disorder, coenzyme Q10 (200 mg/kg) is administered orally to 16 transgenic mice overexpressing a human CuyZn superoxide dismutase (SOD1) mutation, as compared with 13 animals that receive unsupplemented rat chow. The mice used are the G1 line, which expresses high levels of human SOD with the G93A mutation. Treatment is started at 50 days after birth. Treatment is continued until mice reach end-stage disease[3].

生物活性

Coenzyme Q9 (Ubiquinone Q9), the major form of ubiquinone in rodents, is an amphipathic molecular component of the electron transport chain that functions as an endogenous antioxidant. Coenzyme Q9 attenuates the diabetes-induced decreases in antioxidant defense mechanisms. Coenzyme Q9 improves left ventricular performance and reduces myocardial infarct size and cardiomyocyte apoptosis[1][2].

IC50 & Target

Human Endogenous Metabolite

 

体内研究
(In Vivo)

Coenzyme Q9 (5 mg/kg; p.o.; once a day for 4 weeks) reduces myocardial ischemia/reperfusion injury[2].
CoQ10 and CoQ9 are components of themitochondrial respiratory chain in mammals and can regulate some mitochondrial proteins/functions. Soybean, corn, and rapeseed oils are very rich sources of CoQ10, whereas CoQ9 has been found in high concentrations in corn oil[3].
The lack of a functional CoQ9 protein in homozygous CoQ9 mutant (CoQ9(X/X)) mice causes a severe reduction in the CoQ7 protein and a widespread CoQ deficiency and accumulation of demethoxyubiquinone. The deficit in CoQ induces a brain-specific impairment of mitochondrial bioenergetics performance, a reduction in respiratory control ratio, ATP levels and ATP/ADP ratio and specific loss of respiratory complex I. These effects lead to neuronal death and demyelinization with severe vacuolization and astrogliosis in the brain of CoQ9 (X/X) mice that consequently die between 3 and 6 months of age[4].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Hartley guinea pigs of about 350-400 g body weight[2]
Dosage: 5 mg/kg of body weight
Administration: P.o.; once a day for 4 weeks
Result: Nutritional supplementation of CoQ9 can reduce myocardial ischemia/reperfusion injury to the same extent as CoQ10.
