Anyone able to help determine doseage? What does "0.5 to 50nmol/kg/day in mice" translate to in mg/kg in humans?
The usual interspecies scaling constant between mice and humans is a factor of 12 lower for humans, because our metabolism is much slower than a mouse. A mole of SkQ1 is 538g. For the midpoint of the range (which is a factor of 100 wide- a pretty broad mouse dosage range), 5nm/kg/d, it would be:
5nm/kg * (1e-9m/nm) * (538g/m) (1 human/ 12 mouse) = 2.24e-7 g/kg = 22.4 mcg/kg
For a 70kg human:
70kg * 22.4 mcg/kg = 1568 mcg = 1.6 mg
Considering the range that covers a factor of 100, that would result in a dose of between 160 mcg and 16 mg per day.
It might be worth looking at the recommended dose of MitoQ, since SkQ1 and mitoQ have very similar structures.
It's worth noting that these calculated doses are about the same as the dose of c60-oo that people are using. I think c60-oo works in the same way, but with a more effective antioxidant group and possibly less specific mitochondrial targeting. The c60-fatty acid adduct might get incorporated into a phospholipid and join the mitochondrial membrane that way, or it might even enter the membrane by itself, as an anion. This might be opposed by the mitochondrial membrane potential, but favored by the cationic head groups of the native membrane.
Edit: fixed error in units: 160 mcg, not mg!
