CC-223 Usage And Synthesis

Description

CC-223 is a potent, selective, and orally bioavailable inhibitor of mTOR kinase, demonstrating inhibition of mTORC1 (pS6RP and p4EBP1) and mTORC2 [pAKT(S473)] in cellular systems. After tumor-bearing mice was treated with CC-223 for a single oral dose. It exhibited dose-dependent tumor growth inhibition in multiple solid tumor xenografts. The observed antitumor activity of CC-223 is likely to be mediated through inhibition of both mTORC1 and mTORC2. CC-223 is currently in phase I clinical trials for its treatment of advanced solid and hematologic cancers.

Description

CC-223 is a potent inhibitor of mTOR (IC₅₀ = 16 nM) that shows selectivity for mTOR over a panel of 246 other kinases. It blocks signaling through both mTORC1 and mTORC2, inhibiting the phosphorylation of S6RP, 4EBP1, and Akt(S473) in cellular systems. CC-223 inhibits growth and induces apoptosis in hematologic and solid tumor cell lines in vitro, and it exhibits dose-dependent tumor growth inhibition in multiple solid tumor xenografts in vivo.

in vitro

cc-223 was identified as an atp–competitive inhibitor of the mtor kinase targeting mtorc1 of both 4ebp1 and p70 s6 kinase 1 and mtorc2, which prevented the upregulation of akt phosphorylation. moreover, cc-223 was selectively potent to mtor kinase while showed more than 150-fold sensitivity against the related lipid kinase, pi3ka. in addition, cc-223 was active over many non-hodgkin lymphoma cell lines and solid tumor lines such as including glioma, breast, hepatocellular carcinoma, as well as non–small cell lung cancer [1].

in vivo

in animal study, cc-223 was selected for evaluation in pc-3 tumor bearing efficacy mouse models. mice were orally treated with vehicle or various doses of cc-223 once daily or twice daily at a dose of 5 ml/kg for 21 days, and the final reductions of tumor volume were measured following the final day of dosing. results showed that all cc-223 had dose- and schedule-dependent inhibition of tumor growth in the pc-3 model. moreover, the maximum observed efficacy for cc-223 was determined to be 87%, at its tolerated dose of 25 mg/kg q.d. [1].
