Molecular Formula:
Molecular Weight:
AMG-47a is a potent inhibitor of Lck and T cell proliferation. It has anti-inflammatory activity (ED50 = 11 mg/kg) in the anti-CD3 induced production of IL-2 in mice. It displays subnanomolar inhibition against Lck, and low inhibition against other hard to inhibit kinases in several other in vitro assays. It effectively inhibits the JNK family of kinases including TYK2 at ~ 1.2 μM but well under 10 μM. It selectively reduced the levels of EGFP-KRASG12V protein but did not affect EGFP protein in cells.

Mutations in the Ras family of small GTPases, particularly KRAS, occur at high frequencies in cancer and represent a major unmet therapeutic need due to the lack of effective targeted therapies. Past efforts directed at inhibiting the activity of the Ras oncoprotein have proved difficult. We propose an alternative approach to target Ras by eliminating Ras protein from cells with pharmacological means. In this study, we developed a cell-based, high-content screening platform to identify small molecules that could promote the degradation of the KRAS oncoprotein. We generated an EGFP-KRASG12V fluorescence reporter system and implemented it for automated screening in 1536-well plates using high-throughput cellular imaging. We screened a library of clinically relevant compounds at wide dose range and identified Ponatinib and AMG-47a as two candidate compounds that selectively reduced the levels of EGFP-KRASG12V protein but did not affect EGFP protein in cells. This proof-of-principle study demonstrates that it is feasible to use a high-throughput screen to identify compounds that promote the degradation of the Ras oncoprotein as a new approach to target Ras.
