  • Patent number: 8138200
    Abstract: The invention includes compositions and methods useful for treatment of a virus infection in a mammal by double-targeting the virus (i.e. targeting the virus at more than one stage of the virus life cycle) and thereby inhibiting virus replication. The compositions of the invention include compounds which comprise a phosphocholine moiety covalently conjugated with one or more antiviral agents (e.g. nucleoside analogue, protease inhibitor, etc.) to a lipid backbone. The invention also includes pharmaceutical compositions and kits for use in treatment of a virus infection in mammals. The methods of the invention comprise administering a compound of the invention, a pharmaceutically acceptable salt thereof, or a pharmaceutical composition of the invention, in an amount effective to treat the infection, to a mammal infected with a virus. Additionally, the invention includes compositions and methods useful for combating a cancer in a mammal and for facilitating delivery of a therapeutic agent to a mammalian cell.

  • Publication number: 20100273740
    Abstract: Provided are compounds, methods and pharmaceutical compositions for treating a host, especially a human, infected with a togavirus, herpes virus and/or coronavirus, and in particular SARS-CoV, cytomegalovirus or varicella-zoster virus. The method in one embodiment comprises administering to that host an effective amount of an anti-togavirus, anti-herpes virus and/or anti-coronavirus phospholipid or a pharmaceutically acceptable salt or prodrug thereof. The phospholipid compound is, e.g., a 3-alkylamido-2-alkoxypropylphosphocholine compound or salt thereof. The compound may be administered alone or in combination and/or alternation with one or more other anti-viral agents.
