Description:LY2584702 Tosylate (also known as LYS6K2), the tosylate salt of LY2584702, is a selective, orally bioavailable, and ATP-competitive p70S6K (ribosomal p70 S6 kinase) inhibitor with potential antitumor activity. It inhibits p70S6K with an IC50 of 4 nM. LY2584702 showed potent antiproliferative activity in vitro and high antitumor efficacy in vivo by inhibiting ribosomal protein S6 Kinase (p70S6K), and preventing 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.

In Vitro
In vitro activity: In HCT116 colon cancer cells, LY2584702 inhibits phosphorylation of the S6 ribosomal protein (pS6) with IC50 of 0.1-0.24 μM. LY2584702 has significant synergistic effects when combined with EGFR inhibitor erlotinib or with the mTOR inhibitor everolimus.
Kinase Assay: LY2584702 Tosylate (also known as LYS6K2) is a novel, selective, orally bioavailable, ATP-competitive p70S6K inhibitor with IC50 of 4 nM.
Cell Assay: LY-2584702 is fully dissolved in 20 mL 10% DMSO and reserved at -80°C. When conducted the experiments in vitro, LY-2584702 is further diluted in 0.5% Tween 80, 5% propylene glycol and 30% PEG400 to reach different DMSO concentrations of 0.1 μM, 0.2 μM, 0.6 μM, and 1.0 μM. Cell Counting Kit-8 (CCK-8) is used to measure the cells proliferation in vitro. Cell lines A549 and SK-MES-1 treated by LY-2584702 for 24 h with different concentrations are seeded in 96-well plates at a density of 5×103 per well, with six repeats. DMSO treated, or in other words, the concentration of LY-2584702 of 0 is used as negative control. Cells absorbance at 450 nm is detected every 24 h after seeding to measure the proliferative activities[
In Vivo
LY2584702 (12.5 mg/kg BID), demonstrates significant antitumor efficacy in both U87MG glioblastoma and HCT116 colon carcinoma xenograft models.
