Quantitative evaluation of the 1st KER: Binding of inhibitor to NADH‐ubiquinone oxidoreductase (MIE; KE upstream) leads to its inhibition (KE downstream)

MIE (KE upstream) Binding of inhibitor to NADH‐ubiquinone oxidoreductase (nM) KE (downstream) Inhibition of CI (%, approximately) Comments (in vivo, in vitro or human studies) References
Administration of rotenone at 2 mg/kg per day for 2 days resulted in free rotenone concentration of 20–30 nM in the brain 75% DA neuronal cell death determined after rotenone administration at 1–12 mg/kg per day, Sprague–Dawley and Lewis rats infused continuously by jugular vein, 7 days up to 5 weeks Betarbet et al. (2000)
