FCCP (Carbonyl cyanide-4-(trifluoromethoxy)phenylhydrazone) is an ionophore that is a mobile ion carrier. It referred to as an uncoupling agent because it disrupts ATP synthesis by transporting hydrogen ions through a cell membrane before they can be used to provide the energy for oxidative phosphorylation. It is a nitrile and hydrazone. FCCP was first described in 1962 by Heytler.

How to use

In Vitro:

FCCP (5 μM) results in a concentration-dependent decrease in Aβ and APPsβ production in K695sw cells. FCCP inhibits processing of wild-type APP. FCCP does not alter cellular ATP levels at any of the concentrations measured. The effects of FCCP on APP catabolism are independent of secondary effects on oxidative phosphorylation or the result of reduced cell viability. FCCP (5 μM or 500 nM), baf A1, and NH4Cl induce changes in Tf-Tx and Tf-F cellular fluorescence in K695 cells. FCCP (200 nM) protects and enhances the follicle integrity in cat ovarian tissue during short-term in vitro culture. But FCCP does not appear to exert a beneficial or detrimental effect during ovarian tissue cryopreservation.
