- Design, synthesis and anti-proliferative effects in tumor cells of new combretastatin A-4 analogs
-
Abstract A total of 11 novel combretastatin A-4 (CA-4) analogs were designed, synthesized, and evaluated for the anti-proliferative effects in tumor cells. The compounds represent four structural classes: (i) hydrogenated derivatives, (ii) ethoxyl derivatives, (iii) amino derivatives and (iv) pro-drugs. Biological evaluations demonstrate that multiple structural features control the biological potency. Three of the compounds, sit-1, sit-2 and sit-3, have potent anti-proliferative activity against multiple cancer cell lines. Their pro-drugs were synthesized to increase water solubility. Structure-activity relationship study and Surflex-Docking were studied in this paper. These results will be useful for the design of new CA-4 analogs that are structurally related to the SAR study.

- ETHOXY DIPHENYL ETHANE DERIVATES, PREPARATION PROCESSES AND USES THEREOF
-
The invention discloses an ethoxydiphenylethane derivative and a synthetic method and uses thereof 4' position of phenylethane B aromatic ring is chemically modified by ethoxy and hydroxy at position 3' thereof is simultaneously modified to water soluble prodrug such as phosphate, and similarly, amino acid side chain is introduced to amino at position 3' to form amino acid amide water soluble prodrug having the structure shown as formula (I) the ethoxydiphenylethane derivative and the prodrug thereof include strong tubulin aggregation inhibiting ability and obvious target damage effect for tumor vessels, selectively cause dysfunction and structural damage of tumor vessels and induce apoptosis of vascular endothelial cells in order to play the role of killing tumor cells or inhibiting tumor metastasis in case that the tumor cells are free from the support of nutrition and oxygen.

- THE PREPARTION AND THE USE OF ETHOXY COMBRETASTATINS AND THEIR PRODRUGS
-
The invention disclosed a total synthesis process of novel ethoxy combretastatins and their prodrugs. Combretastatins are chemically modified by ethoxy substituted on the 4'-position of their B aryl ring and are converted to be their soluble prodrugs of phosphate or their inner salt of phosphorylcholine by modifying the hydroxyl on the 3'-position of their B aryl ring. Similarly, 3'-amino combretastatin is 4'-ethoxy chemically modified and further side chain of amino acid can be introduced to the amino to form soluble prodrug of amino acidamide. The structure of the said compound is showed as formula (I). Ethoxy combretastatins possess potent tubulin polymerization inhibitory activity and can be used for the treatment of inhibiting tumor or neovascular.
