Notes: BTB06584 (BTB) is an inhibitor of mitochondrial F1FO-ATP synthase (F1FO-ATPase) that has no effect on mitochondrial membrane potential (ΔΨm) or oxygen consumption.{38098} It slows ATP consumption following inhibition of cellular respiration. BTB (100 μM) protects against ischemic cell death of HL-1 cells and rescues defective hemoglobin synthesis in pinotage (pnt) mutant zebrafish. BTB, in combination with ionizing radiation, increases apoptosis of A549 cells.{38097}
