Cell viability in H292 monolayer cells after 3-day treatment and spheroid volume in H292 3D culture after 7-day treatment with ABT751. Data points are means ?SD for three individual experiments. IC50 values were calculated to emphasize the differences in drug potency in 2D verses 3D cultures. ABT751, IC50 of 177.2 ?17.3 nM for 2D and 670.2 ?257.6 nM for 3D.

Western blot analysiswas used to validate the regulation of β1-tubulin to vinculin. (A) Inhibited effects of ABT-751 on the β1-tubulin.Washed human plateletswere treatedwith 0, 2.5, 5, 10 and 20 μg/ml ABT-751 for 60 min then stimulated with 0.3 U thrombin (B) Protein expression of vinculin and Talin1 in washed platelets. The representative bands were from different gels for repeated experiments. After densitometric analysis, the values of proteins were normalized against GAPDH, respectively. Data are shown as the mean ± S.D. (n =3-4 per group). ##P < 0.01 vs normal group, **P < 0.01 vs thrombin group, ++P < 0.01 vs thrombin group.

| In vitro |
In vitro, ABT-751 shows the selective cytotoxicity with IC50 of 0.6–2.6 μM in neuroblastoma and 0.7–4.6 μM in other solid tumor cell lines. Furthermore, ABT-751 also exhibits a selective effect on dynamic microtubules and spares stable microtubules, accounting for the persistence of acetylated and detyrosinated α-tubulin positive polymerized tubules at the IC90 concentration of ABT-751.

| In vivo | In this Calu-6 xenograft model, ABT-751 as a single agent at 100 and 75 mg/kg/day shows significant antitumor activity, while in combination with cisplatin, ABT-751 shows a dose-dependent enhancement in growth delay. In the HT-29 colon xenograft model, ABT-751 also shows significant antitumor activity as a single agent and produced a dose-dependent enhancement in growth delay In combination with 5-FU. [2] In dogs with lymphoma, ABT-751 exhibits the dose-limiting toxicities that included vomiting, diarrhea, anorexia, or some combination of these with a maximum tolerated dose (MTD) of 350 mg/m2 PO q24h. Furthermore, the mean AUC and Cmax for ABT-751 at the MTD of 350 mg/m2 is 5.55 μg-hour/mL and 0.9 μg/mL, respectively. [3] |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
