Purity >98% by HPLC. LY-2584702 is a potent, ATP-competitive inhibitor of p70S6K signaling, with potential antineoplastic activity. LY-2584702 inhibits ribosomal protein S6 Kinase (p70S6K), and prevents phosphorylation of the S6 subunit of ribosomes, thereby inhibiting normal ribosomal function within tumor cells leading to a decrease in protein synthesis and in cellular proliferation.
