METHODS AND RESULTS: Fluorine 19 BMS-747158-01 inhibited mitochondrial complex I (MC-I) in bovine heart submitochondrial particles with an IC (50) of 16.6 +/- 3 nmol/L that was comparable to the reference inhibitors of MC-1, rotenone, pyridaben, and deguelin (IC (50) of 18.2 +/- 6.7 nmol/L, 19.8 +/- 2.6 nmol/L, and 23.1 +/- 1.5 nmol/L, respectively).

A significant contribution by mitochondria was excluded as NADH oxidation by SR exhibited > 9-fold higher catalytic activity (8.8 micromol/mg protein per minute) in the absence of exogenous mitochondrial complex I (ubiquinone) or complex III (cytochrome c) electron acceptors, but was inhibited by rotenone and pyridaben (IC50=2 to 3 nmol/L), antimycin A (IC50=13 nmol/L), and diphenyleneiodonium (IC50=28 micromol/L).
