Tubulysin A
Based on 1 publication(s) in Google Scholar
Tubulysin A (TubA) is an anticancer and antiangiogenic agent with anti-microtubule, anti-mitosis and anti-proliferative activity against a variety of cancer cells with IC50 values in the pmol range. It can induce apoptosis of cancer cells and has no effect on normal cells. Tubulysins are a group of potent cytotoxins consisting of nine members (A-I). Tubulysin A can synthesize ADC as ADC Cytotoxin.

The IC50 values of Tubulysin A in the NCI-H1299 (lung), HT-29 (colon) and A2780 (ovary) cell lines are 3, 1 and 2 nmol/L, respectively[4].
The IC50 values of Tubulysin A against L929 (mouse fibroblast) and KB-V1 (human cervical cancer multidrug resistant cell line) cells were 0.07 and 1.4 ng/ml, respectively[1].
Tubulysin A (1 nM, 10 nM; 24h) has an antiangiogenic effect in HUVEC cells with IC50 values of 2.07-2.97 nM[1].
Tubulysin A (5h) can inhibit cell migration in HUVEC cells with IC50 value of 2.26 nM[1].
Tubulysin A (72h) can inhibit cell growth in HUVEC cells with GI50 value of 0.34 nM[1].

Solvent & Solubility
DMSO : 100 mg/mL (118.47 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light, stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (2.96 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (2.96 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
