| In vitro study | Combretastatin A4 inhibits the growth of MDA-MB-231,A549,Hela,HL-60,SF295,HCT-8,MDA-MB435,PC3M,OVCAR-8,NCI-H358M, and lymphocytes with IC50 of 2.8,3.8,0.9,2.1, respectively, 6.2,5.3,7.9,4.7,0.37,8, and 3.2 nM. 1 μm Combretastatin A4 inhibited tubulin polymerization by 35% and 10 μm almost completely blocked tubulin polymerization. Combretastatin A4 showed a high relative binding capacity, reaching 78% of the colchicine binding capacity. |
| In vivo study | In NT2 and MDA-MB-231 breast tumor models, Combretastatin A4 (100 mg/kg, I. p.) A significant decrease in lipid R1 was induced and a decrease in pO2 was measured by electron paramagnetic resonance (EPR) oximetry. Combretastatin A4 (100 mg/kg, I. p.) significantly reduced K in male NMRI mice |

Combretastatin A4 117048-59-6 - Reference Information
| introduction | compretin A4 is an effective tubulin polymerization inhibitor with strong inhibitory activity on tumor cell growth. It can inhibit tumor growth of many cell lines, including IMR32 (neuroblastoma), Hs746T (gastric cancer), CFPAC-1 (pancreatic cancer) and MCF-7 (breast cancer), with IC50 values of 2.16, 5.20, 3.46, and 18.47 nM, respectively. CA4 inhibits tubulin polymerization with an IC50 value of 2.2 μM. |
| pharmacological effects | compretin A4 has the effects of inhibiting angiogenesis, inhibiting tumor growth and resisting cancer. |
| mechanism of action | CA4 targets tubulin in vivo, inhibits its polymerization, and further destroys tumor blood vessels, thus playing an anti-tumor effect, which is effective in various tumor models. CA4 has little effect on normal cells, selectively destroys the vascular endothelial cells of tumor tissue, closes the blood vessels of tumor tissue, and leads to tumor hypoxia and hypoxia. |
| Biological activity | Compretin A4 is a reagent targeting microtubule, which binds to β-tubulin, and Kd is 0.4 μM. Phase 3. |
| Target | Value |
| β-tubulin | 0.4 μM(Kd) |
