Biological Activity
Avanbulin (0-4 μM) binds to tubulin in the site as Colchicine with an apparent Kd value of 244 nM.[1].
Avanbulin (50 μM; 0, 10, 20, 30, 60 min) induces the proteolysis of tubulin[1].
Avanbulin (33 nM; 0, 10, 20, 30, 60 min; HeLa-tubGFP cells) collapses the mitotic spindle and forms the tiny tubulin aggregates[1].
Avanbulin does not induce the formation of tubulin oligomers[1].
Avanbulin induces growth inhibition of 23 tumor cell lines with a median relative IC50 of 13.8 nM (96 hours) [2].
Avanbulin (6 nM and 20 nM) inhibits the migration of GBM6 and GBM9 cells[3].
Avanbulin (6 nM and 20 nM; GBM6-shEB1 and GBM6-sh0 cells) triggers astrocytic differentiation of GBM6 in an EB1-dependent manner[3].
Avanbulin (12 nM; 4 h) reduces kinetochore-microtubule (KT-MT) occupancy of MG132(10 μM; 2h) treated hTert-RPE1 eGFP-α-tubulin cells[4].
Avanbulin (12 nM; 4 h) reduces average inter-KT distances of cells, shows intact spindle morphology, and lacks obvious chromosome alignment defects[4].

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.
