Method for protection against tumor metastasis formation

Methods and pharmaceuticals for inhibiting or preventing metastasis formation in animals, including humans, having primary tumors, through the administration of phosphorothioates including their thiol and disulfide metabolites are disclosed. These compounds stimulate angiostatin levels, inhibit matrix metalloproteinases (MMPs), and stimulate manganese superoxidase dismutase (MnSOD). Phosphorothioates, of which amifostine is an example, can be administered as a combination therapy with traditional cancer therapies, including chemotherapy, radiotherapy, surgery, immunotherapy, hormone therapy and gene-therapy. Inhibition or prevention of metastasis by phosphorothioates is independent of tumor type, including adenocarcinomas and sarcomas.

Method for preparing amifostine

The invention relates to a method for preparing amifostine, comprising the following steps: a) reacting phthalimide with 1,3-dibromopropane in dipolar aprotic solvents to genenrate N-(3-bromopropyl) phthalimide; and b)reacting N-(3-bromopropyl) phthalimide with 2-oxazolidinone in dipolar aprotic solvents to generate 2,2-[3-(2-carbonyl-3-oxazole)propyl]-1H-isoindole-1,3(2H)-diketone; and using the one-pot process to prepare the amifostine directly from the intermediate 2,2-[3-(2-carbonyl-3-oxazole)propyl]-1H-isoindole-1,3(2H)-diketone, thus the production process can be simplified, and the production cost can be saved. In addition, primary amine is obtained by hydrazinolysis, thus the reaction conditions are mild, the side effect is low, and the post-treatment is simple. The method has the characteristics of easy obtainment of raw materials, low price, safe and convenient usage, little pollution, easy transportation, and the like.
