12534287 Nakamaru-Ogiso E, Sakamoto K, Matsuno-Yagi A, Miyoshi H, Yagi T: The ND5 subunit was labeled by a photoaffinity analogue of fenpyroximate in bovine mitochondrial complex I. Biochemistry. 2003 Jan 28;42(3):746-54.

Fenpyroximate is a potent inhibitor of the mitochondrial proton-translocating NADH-quinone oxidoreductase (complex I).

Class I inhibitors, including the naturally occurring piericidin A, annonin VI, phenalamid A2, aurachins A and B, thiangazole and the synthetic fenpyroximate, inhibit complex I from all three species in a partially competitive manner and glucose dehydrogenase in a competitive manner, both with regard to ubiquinone.

The ATP content in bifenazate treated mites declined progressively between 0 and 4h after treatment, similarly to mites treated with the complex I inhibitor fenpyroximate, an acaricide known to interfere with mitochondrial function.

The diverse inhibitors of bovine heart mitochondrial complex I (NADH-ubiquinone oxidoreductase) are believed to share a common large binding domain with partially overlapping sites, though it remains unclear how these binding sites relate to each other.
The cross-linking was completely blocked by excess amounts of other inhibitors such as acetogenin and fenpyroximate.

12914922 Nakamaru-Ogiso E, Seo BB, Yagi T, Matsuno-Yagi A: Amiloride inhibition of the proton-translocating NADH-quinone oxidoreductase of mammals and bacteria. FEBS Lett. 2003 Aug 14;549(1-3):43-6.

The proton-translocating NADH-quinone oxidoreductase in mitochondria (complex I) and bacteria (NDH-1) was shown to be inhibited by amiloride derivatives that are known as specific inhibitors for Na (+)/H (+) exchangers.
These results together with our earlier observation that the amiloride analogues prevent labeling of the ND5 subunit of complex I with a fenpyroximate analogue suggest the involvement of ND5 in H (+) (Na (+)) translocation and no direct involvement of electron carriers in H (+) (Na (+)) translocation.

J Biol Chem. 2005 Dec 30;280(52):42655-68. Epub 2005 Oct 19.


C. elegans lines with these genetic changes were more vulnerable than nontransgenic nematodes to mitochondrial complex I inhibitors, including rotenone, fenperoximate, pyridaben, or stigmatellin.
