RPS6-IN-1 (Compound 22o) inhibits cell metastasis, induces cell apoptosis (increases the expression of Bax, p53, cleaved-caspase 3, and cleaved-PARP). RPS6-IN-1 decreases mitochondrial membrane potential. RPS6-IN-1 activates autophagy through the PI3K-Akt-mTOR signaling pathway, damages intracellular mitochondria and lysosomes, and cause ER stress. RPS6-IN-1 inhibits RPS6 phosphorylation. RPS6-IN-1 is an anticancer agent with low systemic toxicity[1].
