🥰Excellent
A-259745 is an orally active antimitotic agent that binds to the colchicine site on tubulin. It exhibits potent in vitro cytotoxic activity against both multidrug-resistant and non-multidrug-resistant cancer cell lines, with ED50 values of 0.018 μM for HCT-15 and 0.028 μM for NCI-H460 cells. A-259745 inhibits tubulin polymerization, disrupting the dynamic equilibrium of the mitotic spindle, causing dividing cells to arrest in the metaphase-anaphase transition, which subsequently induces apoptosis (apoptosis). In mouse tumor models, A-259745 demonstrates dose-dependent antitumor efficacy and is useful for cancer research.

In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
