英文摘要: Combretastatins (CA4), originally isolated from the South African willow tree Combretum caffrum, are the potent inhibitors of tubulin ploymerization. A series of gem-difluorinated CA4 derivatives will be designed and synthesized based on the structural analysis of CA4 and target tubulin complex, using the computer-aided drug design strategy.The inhibitions of tubulin polymerzation and the anti-tumor effects of all the derivatives will be assayed in vitro.The binding mechanism of CA4 derivatives with tubulin will be studied with docking and molecular dynamics. The relationship between different fluoro-aubatitutions and bioactivities will be figured out with 3D-QSAR study. All the results can help us to discover independent intellectual property rights small molecules as high efficiency and low toxicity targeting anticancer drugs.
