Atractyloside Dipotassium Salt is an inhibitor of ADP/ATP Translocase.
ATP-ADP translocase (AAT) is a mitochondrial ADP/ATP carrier. It transports ATP from the mitochondrial matrix to the cytoplasm and transports ADP from the cytoplasm to the mitochondrial matrix.
In Ehrlich ascites tumor cells, atractyloside (3 mM) inhibited cells growth by 70%. The mitochondria became spherical shaped with translucent matrix rid of cristae. When transfered to normal medium, proliferation and macromolecular synthesis recovered to normal levels within 3 to 6 h [2].
In the sarcoplasmic reticulum vesicles from the rabbit skeletal muscle with 10 μM of cytoplasmic Ca2+, atractyloside reduced the rate of choline+ influx through the Ca2+ channels to 60%. Also, it inhibited about half of Ca2+ channels incorporated into planar bilayers [1]. In mitochondrial membranes isolated from a rat heart muscle, atractyloside (5-100 μM) inhibited the chloride channels in dose-dependent way [3].
