  • Patent number: 10669295
    Abstract: Preparation of O,O-dimethyl phosphoramidothioate and O,O-dimethyl phosphoroamidothioate. A process of making O,O-dimethyl phosphoroamidothioate is described including reacting sulfur with PCl3 to form PSCl3, reacting the PSCl3 formed with methanol to form O-methyl phosphorodichloridothioate, and reacting the O-methyl phosphorodichloridothioate formed with methyl lye to form O,O-dimethyl phosphorochloridothioate in solution in CH2Cl2, and reacting the O,O-dimethyl phosphorochloridothioate formed with sodium hydroxide and ammonium hydroxide to form O,O-dimethyl phosphoroamidothioate in solution in CH2Cl2. Reacting the O,O-dimethyl phosphoroamidothioate formed with catalytic dimethyl sulfate to form methamidophos, and reacting the methamidophos formed with acetic anhydride to form N-(methoxy-methylsulfanylphosphoryl) acetamide is also described. Throughout the process, the O,O-dimethyl phosphorochloridothioate and the O,O-dimethyl phosphoroamidothioate formed are maintained in solution in CH2Cl2 at all times.

  • Patent number: 5274162
    Abstract: The composition, methods of synthesis, and applications of a new class of tumor selective antineoplastic drugs is described. These novel antineoplastic agents are of the general structure: A-C-B. The agents are designed with two key functionalities: a trigger which toxifies the drug; (A) and a deactivator which detoxifies the drug (B) The trigger is selected such that it is activated by an enzyme which is present in elevated levels in the tumor. The deactivator is selected such that it is actuated by an enzyme ubiquitous to all tissues. The fate of the drug in a given cell is then determined by the ratio of the enzymatic activity that triggers toxication to the enzymatic activity which detoxifies the drug. The partitioning of the drug between toxic metabolite and nontoxic metabolite defines the resulting specificity of cytotoxic effect.
