J. Enzyme Inhib. Med. Chem. | Protac Targeting Aimp2-Dx2: a New Therapy For Lung Cancer

Recently, Inhee Choi's group at the Pasteur Institute in Korea reported in the Journal of Enzyme Inhibition and Medicinal Chemistry a novel PROTAC degrader (compound 45) targeting the AIMP2-DX2 protein. The experimental data confirmed that compound 45 overcomes the disadvantage of the low activity of the original small molecule inhibitor by targeting binding to degrade the AIMP2-DX2 protein, and offers a new opportunity for the treatment of lung cancer.

1, Representative molecules

2,Targets and indications
Target: AIMP2-DX2 target protein
Potential indications: lung cancer

3,Synthesis pathway

4,Biological activity
In vitro experiments have shown that compound 45 significantly degrades AIMP2-DX2 protein at concentrations above 3 μM (see left below) and that compound 45-mediated anti-proliferative efficacy of AIMP2-DX2 is dependent on Siah1 levels, and that compound 45-mediated degradation of the target protein is lost when Siah1 is knocked out of the cells (see right below).
