Anilinopyrazines as potential mitochondrial uncouplers.

In this study, we report the structure-activity relationship profile of the pyrazine scaffold bearing substituted aniline rings. Our work indicates that a trifluoromethyl group is best at the para position while the trifluoromethoxy group is preferred in the meta position of the aniline rings of 2,3-substituted pyrazines. As proton transport and cycling requires the formation of a negative charge that has to traverse the mitochondrial membrane, a stabilizing internal hydrogen bond is a key feature for efficient mitochondrial uncoupling activity.
