BC-DXI-843 is a potent and specific AIMP2-DX2 inhibitor with an IC50 of 0.92 μM, more than 100-fold selectivity over AIMP2 (IC50 >100 μM) in a luciferase assay. BC-DXI-843 acts as a promising lead targeting AIMP2-DX2 in lung cancer[1].
BC-DXI-843 (0.0316-31.6 μM; 72 hours) suppresses cancer cell proliferation in a DX2-dependent manner. The EC50 in A549 cells is 1.20 μM, which is similar to the IC50 for inhibition of DX2. However, no inhibition of WI-26 cells is observed, suggesting that BC-DXI-843 specifically reduces the viability of cancer cells[1]. Cell Proliferation Assay[1] Cell Line: A549 cancer cells and WI-26 normal cells
BC-DXI-843 (50 mg/kg; intraperitoneally administered; every other day for 15 days) demonstrates in vivo efficacy in a tumor xenograft mouse model (H460 cells)[1]. Animal Model: 7-week-old female BALB/cSLC-nu/nu mice bearing H460 cells xenograft[1]
