Abstract
Described is a fluorine-containing compound shown in Formula II/III and its anti-cancer medical use. The present application creatively introduced the fluorine-containing groups such as special trifluoromethyl groups, fluorine-substituted aryl groups, or heteroaryl groups at special positions (such as the position between the nitrobenzene ring and the phosphate amine group) in the structures of the above compounds. After this modification, it was found that all of the resulting compounds were solids (including waxes).
