BO-264 is a novel and orally bioactive transforming acidic coiled-coil 3 (TACC3) inhibitor with an IC50 of 188 nM and a Kd of 1.5 nM. Through spindle assembly checkpoint (SAC)-dependent mitotic arrest, DNA damage, and apoptosis, BO-264 showed superior anti-proliferative activity compared to the two currently known TACC3 inhibitors, particularly in aggressive breast cancer subtypes, basal and HER2+. The cytotoxicity against normal breast cells was minimal.
| Targets |
FGFR3; TACC3 (Kd = 1.5 nM); TACC3 (IC50 = 188 nM)

| ln Vitro |
BO-264 substantially reduces centrosomal TACC3 in interphase and mitosis. In the NCI-60 cell line panel, which compromises nine distinct cancer types, BO-264 exhibits strong anti-proliferative activity. BO-264 is a powerful growth inhibitor of cells expressing the FGFR3-TACC3 fusion, an oncogenic driver found in a variety of cancers.[1]
|
| ln Vivo |
BO-264 (25 mg/kg; oral administration; daily; for 3-4 weeks; female nude mice) treatment shows a significant suppression of tumor growth. Since BO-264 does not result in organ toxicity or a considerable reduction in body weight, it is well tolerated.
|
| Cell Assay |
Briefly, BO-264 (1 μM) or vehicle is incubated for 6 hours with JIMT-1 cells. Protease and phosphatase inhibitors are added to Tris-buffered saline (TBS) buffer, which is used to resuscitate cell pellets following treatment. Six PCR tubes containing the cell suspension are filled, and the temperature is raised to 45, 46, 47, 48, 49, and 50 °C for five minutes. Three consecutive cycles of freeze-thaw with liquid nitrogen are then used to lyse the cells. Western blot analysis and SDS-PAGE are used to analyze soluble proteins after they are collected by centrifugation at 20,000 g for 20 minutes at 4 °C.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (5.89 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (5.89 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
