Description

Technical field: The invention relates to antitumor compounds for use in therapy, methods of their use, formulations containing them and methods of their production. technical background: Combretastatin is isolated from the South African tropical plant Combretum Caffrum. It can quickly combine with tubulin, has a good selective anti-mitotic effect, destroys tumor blood vessels, causes the death of tumor vascular endothelial cells, and leads to the death of secondary tumor cells, and has extremely high anti-tumor activity , has great clinical application value. However, the water solubility of combretastatin and its derivatives is extremely poor, which largely limits the clinical use of combretastatin and its derivatives, and the design and preparation of water-soluble prodrugs is a research hotspot. Invention content: The purpose of the present invention is to provide a new derivative of combretastatin compound for treating tumors. Its structure is: R 1 -O-(CH 2 ) ...
