Potent mitochondrial
uncoupler
Abstract.
Studies on an acaricide with mitochondrial uncoupling activity
[fentrifanil; 2'-chloro-2,4-dinitro-5',6-di(trifluoromethyl)-diphenylamine]
are presented. Isolated mitochondria (from mice livers) were incubated
with fentrifanil, and oxygen uptake was measured polarographically
using a Clark oxygen electrode. The ADP ratio, respiratory control
index (RCI), and stimulation of state 4 respiration were also
measured. Fentrifanil was found to stimulate oxygen consumption,
reduce the RCI, lower the ADP/O ratio, and release the oligomycin
block of ADP-stimulated respiration. In
terms of the concentration required to decrease the RCI value
by 50%, fentrifanil was about 4500-fold more potent than 2,4-dinitrophenol
and slightly more potent than carbonylcyanide m-chlorophenylhydrazone
(MCCP).
