The present invention provides a fructose analogue and a composition thereof which can be used for cancer treatment, has a targeting effect and has little effect on normal cells, particularly when used in the treatment of acute myeloid leukemia (‘AML’) and pancreatic cancer and other types of cancer having similar metabolic characteristics. In the present invention, the fructose analog is selected from the group consisting of 2,5-anhydro-D-mannitol and the 5-anhydro-D-mannitol derivative substituted at the 1-position or 6-position by an amino group, an alkyl group or an aryl group, anhydro-D-mannitol tetraacetate and 2,5-anhydroglucitol and the like. The fructose analogs of the present invention can be used to prepare and treat cancer drugs and can be prepared as injectable preparations or oral preparations. The fructose analogues of the present invention can be used in combination with conventional anticancer drugs when used in the preparation of a medicament for the treatment of cancer. The fructose analogs of the present invention can be used in combination with glucose analogues in the treatment of cancer or organ fibrosis.
