Abstract: Disclosed is a 5-fluorouracil derivative having the molecular structure shown in general formula VI, in which Ra and Rb groups are an alkoxy group or a fluorine-substituted alkoxy group having 1, 2, 3, or 4 carbon atoms, and are mono-, bis-, tri-, tetra- or penta-substituted on a phenyl group; a linking group L1 is an alkyl or alkenyl group having 1, 2, 3, or 4 carbon atoms, a linking group L2 is oxygen, or an alkyl or alkoxy group having 1, 2, 3, or 4 carbon atoms, or an amino acid, or an alkyl group having 1, 2, 3, or 4 carbon atoms containing an amino moiety, or a furyl group, and an X group is O or —NH—. Further disclosed is a method for preparing such a derivative and a use of the same in the treatment of cancer, tumor diseases, and diseases caused by abnormal neovascularization in a human or non-human mammal, and a medicament or a composition containing the 5-fluorouracil derivative.

Abstract: The invention discloses CA-4 antitumour drug, their synthetic methods and applications. The CA-4 antitumour drug are obtained by introducing an alkoxy group or a fluorine-containing alkoxy group at the 4? position of the natural product Combretastatin and modified with a functional chemical group at its 3? position. The CA-4 derivated anti-tumor drugs of the invention have inhibitory ability on two targets related to tubulin and arylsulfatase, and can be used for anti-tumor treatment.

Abstract: The present invention relates to compounds which act as modulators of the chloride channel CLC-7, assays for the identification of such compounds and methods of preventing, diagnosing, and treating osteoporosis and related disease states using such compounds.
