title: Non-HIV antivirals - a review of the recent patent literature.
abstract: This review covers the non-HIV antiviral patent literature from December 2001 to April 2002. Most of the patent applications describe new compounds for the treatment of hepatitis C virus (HCV) by inhibition of the NS3 serine protease. Several examples of both nucleoside and non-nucleoside inhibitors of the HCV polymerase NS5B have been reported. Hepatitis B virus (HBV) therapy continues to be dominated by nucleoside analogs, but several non-nucleoside HBV polymerase inhibitors have also been reported. In addition, a number of patents describing non-nucleoside inhibitors of the human cytomegalovirus (HCMV), the herpes simplex virus (HSV-1 and HSV-2) and the varicella zoster virus (VZV) DNA polymerase are also reviewed. A number of patents that appeared in 2002 hold promise for the treatment of respiratory syncytial virus (RSV) with small molecule inhibitors. Various approaches to the treatment of hepatitis D virus (HDV), picornaviruses and the human papilloma virus (HPV) are also described.
