BO-264 is a highly potent and orally activetransforming acidic coiled-coil 3 (TACC3)inhibitor with anIC₅₀of 188 nM and aK_dof 1.5 nM. BO-264 specifically blocks the function ofFGFR3-TACC3fusion protein. BO-264 induces spindle assembly checkpoint (SAC)-dependent mitotic arrest, DNA damage andapoptosis. BO-264 has broad-spectrum antitumor activity^[1].

IC50: 188 nM (Transforming acidic coiled-coil 3 (TACC3))^[1]
Kd: 1.5 nM (TACC3)^[1]

BO-264 (500 nM; 48 hours; JIMT-1 cells) treatment induces a prominent increase (from 4.1% to 45.6%) in the fraction of apoptotic cells as assessed by Annexin V/PI staining^[1].
BO-264 (500 nM; 24 hours; RT112 cells) treatment decreases ERK1/2 phosphorylation, which is a marker for activated FGFR signaling along with a strong mitotic arrest^[1].
BO-264 inhibits cell viability with IC₅₀values of 190 nM, 160 nM, 120 nM, 130 nM and 360 nM for JIMT-1, HCC1954, MDA-MB-231, MDA-MB-436 and CAL51, respectively. BO-264 specifically targets breast cancer cells while sparing normal cells. BO-264 treatment significantly reduces the average colony number of JIMT-1 cells^[1].
BO-264 inhibits the viability of cancer cells with FGFR3-TACC3 fusion with IC₅₀values of 0.3 μM and 3.66 μM for RT112 and RT4, respectively^[1].
BO-264 exhibits a remarkable anti-cancer activity against more than 90% of the NCI267 60 human cancer cell lines representing nine different subpanels with GI₅₀values less than 1 μM^[1].
BO-264 induces mitotic arrest (prominent induces p-Histone H3 (Ser10)), apoptosis (cleaved PARP) and DNA damage, causes aberrant spindle formation and reduces centrosomal localization of TACC3 in JIMT-1 cells^[1].

BO-264 (25 mg/kg; oral administration; daily; for 3-4 weeks; female nude mice) treatment shows a significant suppression of tumor growth. BO-264 is well tolerated since treatment does not causes a significant body weight loss and organ toxicity^[1].
