The % Control complex I activity as monitored by NADH oxidation (white columns) and DCIP reduction (grey columns) for each of the ten compounds tested at concentrations of 0.5, 1.0 and 5.0μM. Each compound was incubated with the SMP for at least two minutes before the addition of NADH. The specific activity of the complex I enzyme in the presence of the three concentrations of compounds was compared to total rotenone sensitive activity (DMSO control-Rotenone control).
