Abstract
Short-chain quinones have been investigated as therapeutic molecules due to their ability to modulate cellular redox
reactions, mitochondrial electron transfer and oxidative stress, which are pathologically altered in many mitochondrial and
neuromuscular disorders. Recently, we and others described that certain short-chain quinones are able to bypass
a deficiency in complex I by shuttling electrons directly from the cytoplasm to complex III of the mitochondrial respiratory
chain to produce ATP. Although this energy rescue activity is highly interesting for the therapy of disorders associated with
complex I dysfunction, no structure-activity-relationship has been reported for short-chain quinones so far. Using a panel of
70 quinones, we observed that the capacity for this cellular energy rescue as well as their effect on lipid peroxidation was
influenced more by the physicochemical properties (in particular logD) of the whole molecule than the quinone moiety
itself. Thus, the observed correlations allow us to explain the differential biological activities and therapeutic potential of
short-chain quinones for the therapy of disorders associated with mitochondrial complex I dysfunction and/or oxidative
stress.
