The adenine nucleotide translocase (ANT) mediates ADP/ATP
exchange in mitochondria and is also a critical component of the
mitochondrial permeability transition (MPT) pore. Opening of this
physiological pore has been implicated as a key step in initiating
cell death, hence agents that prevent MPT pore opening may be of
potential therapeutic value. The natural product bongkrekic acid
is a potent ANT inhibitor that is reported to block MPT opening.
We present the design and synthesis of N-acyl
iminodiacetic acids as novel inhibitors of ANT-1, using bongkrekic
acid as an initial lead. The identification of potent ANT-1 inhibitors
from a primary binding assay and the preliminary structure-activity
relationship based on these new leads are discussed.
