Notes: BO-264 is a transforming acidic coiled-coil containing protein 3 (TACC3) inhibitor.{66140} It binds to TACC3 in thermal shift and drug affinity responsive target stability (DARTS) assays and inhibits the growth of JIMT-1, HCC1954, MDA-MB-231, MDA-MB-436, and CAL-51 cancer cells (IC50s = 0.19, 0.16, 0.12, 0.13, and 0.36 µM, respectively). BO-264 is cytotoxic to RT4 cells that endogenously express TACC3-FGFR3 fusion proteins (IC50 = 3.66 µM). It induces mitotic arrest, apoptosis, and aberrant spindle formation and reduces centrosomal localization of TACC3 in JIMT-1 cells. BO-264 (25 mg/kg) reduces tumor volume and increases median survival in an EMT6 mouse xenograft model.
