Description: AT13148 is a novel oral multi-AGC kinase inhibitor with potent pharmacodynamic and antitumor activity, which shows a distinct mechanism of action from other AKT inhibitors. AT13148 is currently being developed by Astex Pharmaceuticals. AT131148 was identified utilizing high-throughput X-ray crystallography and fragment-based lead discovery techniques. AT13148 caused substantial blockade of AKT, p70S6K, PKA, ROCK and SGK substrate phosphorylation and induction of apoptosis in both a concentration and time-dependent manner in cancer cells with clinically relevant genetic defects both in vitro and in vivo.

Biological target: AT13148 is an ATP-competitive, multi-AGC kinase inhibitor with IC50s of 38 nM/402 nM/50 nM, 8 nM, 3 nM, and 6 nM/4 nM for Akt1/2/3, p70S6K, PKA, and ROCKI/II, respectively.
In vitro activity: AT13148 potently inhibited proliferation with GI50 values of 1.5 to 3.8 μmol/L across a selected panel of cancer cell lines (Supplementary Table S3) representing common human malignancies with deregulation of PI3K-AKT-mTOR or RAS-RAF pathways. The effect of 1-hour exposure to AT13148 on AKT and p70S6K signaling was initially explored in PTEN-deficient U87MG glioblastoma cells (Fig. 2A). Marked induction of pSer473 AKT occurred at all concentrations. Nevertheless, phosphorylation of the 2 AKT substrates GSK3β and PRAS40 was inhibited at AT13148 concentrations >1 and 5 μmol/L AT13148, respectively.

In vivo activity: In contrast, in AT13148 treated mice, tumor cells homed and grew on the pancreas, but a clearly demarcated border was consistently observed between tumor and normal tissue (Fig. 6A lower panels). When the area of the invasive region, in which tumor cells were intermixed with normal pancreas cells, was expressed as a percentage of the total pancreas for each condition, there was a significant decrease in the invasive region for AT13148 treated mice (Fig. 6A), which approached significance for the less potent ROCK inhibitor fasudil treated mice (Fig. 6B). To determine whether the anti-invasive effect of AT13148 treatment was due to decreased proliferation, mice were injected with bromodeoxyuridine (BrdU) 2 h before sacrifice, and then tissues were stained with anti-BrdU antibody (Fig. 6C). Counting the percentage of BrdU positive tumor cells indicated that there was no effect of AT13148 on proliferation (Fig. 6D), indicating that reduced invasion of pancreatic tissue was a direct effect on invasive behaviors.

Additional Information

AT13148 is an orally active small molecule inhibitor of PKB/Akt and p70S6 kinase, key enzymes in the PI3K/PKB/mTOR tumor cell survival pathway. AT13148 has the potential to be a very effective inhibitor of AKT dependent tumors. In September 2008 Astex announced a partnership with Cancer Research UK and CRT to take AT13148 into development under the charity's Clinical Development Partnerships (CDP) program. Under the terms of this agreement, Cancer Research UK's Drug Development Office has carried out further development work on the agent, some of which is done in collaboration with the ICR. CRUK plans to commence phase 1 clinical trials of AT13148 at the Royal Marsden Hospital in the UK during 2012.  (source:http://astx.com/pipeline/products/clinical).
