专利号:US-RE37623-E 优先权日:1993-11-02 标题:Enzyme inhibitors, their synthesis, and methods for use 发明人:EL KOUNI MAHMOUD H; NAGUIB FARDOS N M; SCHINAZI RAYMOND F 权利人:EL KOUNI MAHMOUD H; NAGUIB FARDOS N M; SCHINAZI RAYMOND F 摘要:Novel compounds are provided that are effective to inhibit the activity of DHUDase or UrdPase. Such compounds have the general formula n where X is S or Se; Y is H, I, F, Cl, Br, methoxy, benzyl, selenenylphenyl, or thiophenyl, and R 1 is H or an acyclo tail having the general formula n where R 2 is H, CH 2 OH or CH 2 NH 2 ; R 3 is OH, NH 2 , or OCOCH 2 CH 2 CO 2 H; and R 4 is O, S, or CH 2 . n The compounds can be used in pharmaceutical compositions, along with various chemotherapeutic agents to increase the efficacy of the treatment. These compounds can also be used in methods of treating patients by coadministering or sequentially administering the enzyme inhibiting compounds with a chemotherapeutic agent effective to treat cancers, or viral, fungal, bacterial, or parasitic infections. The compounds have further utility in enhancing imaging. Further, they can be administered alone to prevent and/or treat disorders of pyrimidine catabolism and other physiological disorders.
