Abstract:
The disclosed invention is a bicyclo[4.2.1]nonane and its pharmaceutically acceptable salt or prodrug, and its composition and method of use to treat Flaviviridae (Hepacivirus, Flavivirus, and Pestivirus) infections on a host, including animals, and especially humans.
Abstract:
The disclosed invention is a composition for and a method of treating a Flaviviridae (including BVDV and HCV), Orthomyxoviridae (including Influenza A and B) or Paramyxoviridae (including RSV) infection, or conditions related to abnormal cellular proliferation, in a host, including animals, and especially humans, using a nucleoside of general formula (I)-(XXIII) or its pharmaceutically acceptable salt or prodrug. This invention also provides an effective process to quantify the viral load, and in particular BVDV, HCV or West Nile Virus load, in a host, using real-time polymerase chain reaction ("TR-PCR"). Additionally, the invention discloses probe molecules that can fluoresce proportionally to the amount of virus present in a sample.
