Abstract: HTS screening was performed on cell proliferation, which is typically one of the symptoms of aging. Obtained as a result was compound KB1541, which was the compound most effective for cell proliferation. The present invention was developed by studying the mechanism by which the drug controls cell proliferation and aging. A drug in which biotin is linked to KB154 was treated, and streptavidin-magnetic beads were used to determine what proteins interact with the drug; and as a result, it was determined that mitochondrial proteins interact with the drug. It was confirmed, via ATP assay, electron microscopy, and IP experiments, that the drug regulates mitochondrial proteins and consequently assists in increasing ATP production and reversing the effects of aging.
