(A–F) Structures of S1QEL1s and dose-response curves against site IQ (site of respiratory complex I active during reverse electron transport, nominally the ubiquinone binding site), site IF+DH (flavin site of complex I and predominantly the 2-oxoglutarate dehydrogenase complex, site OF), and site IIIQo (outer ubiquinone-binding site of complex III) normalized to DMSO control = 1.0.
(G–J) Structures of S1QEL2s and dose-response curves.
Data are means ± SE of n = 3 technical replicates (n = 2 for IF+DH) (step 10 in Table 1). IC50 values against superoxide-H2O2 production from site IQ are means ± SE, n = 3 (n = 5 for S1QEL1.1 and S1QEL2.1).
