  1. In vitro percent activity of each of the four ETC complexes in response to treatment with 100 µM of NPD hit compounds. Percent activity of each complex in response to inhibitors was calculated relative to the corresponding solvent controls. Data are the mean of at least three biological replicates; errors represent SEM.
