New antiviral agents.
During the last three decades, a better understanding of viral replication and disease states caused by viral infections have led to the development of newer antiviral agents with enhanced activity and better tolerability. This review focuses on newer systemic and topical antiviral agents that are used in treatment of herpes viruses including herpes simplex type-1 (HSV-1) and type-2 (HSV-2), varicella-zoster virus (VZV) and cytomegalovirus CMV) as well as the human papilloma virus (HPV). Included in this article are the agents famciclovir, penciclovir, valganciclovir, imiquimod, docosanole and brivudin.

Antiviral agents for non-human immunodeficiency virus infections.
Several new agents for treating viral infections have been developed in recent years. All available agents are virustatic, inhibiting specific steps in the process of viral replication. No agent is active against nonreplicating or latent viruses. Acyclovir is useful in the treatment of genital herpes, herpes simplex encephalitis, mucocutaneous herpetic infection, varicella infection in the immunosuppressed host, and herpes zoster infection in the normal and the immunosuppressed host. It can also be used for prevention of herpesvirus infection in immunocompromised patients. Ganciclovir is indicated for the treatment of cytomegalovirus retinitis in patients with the acquired immunodeficiency syndrome and is effective in the treatment and prevention of cytomegalovirus infection in other immunocompromised patients. Famciclovir and valacyclovir are effective in the management of herpes simplex and varicella-zoster infection. Amantadine and rimantadine are useful therapeutically and prophylactically in the management of influenza A virus infection. Chronic hepatitis B infection can respond to lamivudine therapy, and the optimal treatment of hepatitis C is the combination of interferon alfa and ribavirin. Despite pronounced toxic effects, foscarnet and cidofovir are effective antiviral agents in specific settings.

Synthesis and preliminary evaluation of 9-(4-[18F]-fluoro-3-hydroxymethylbutyl)guanine ([18F]FHBG): a new potential imaging agent for viral infection and gene therapy using PET.
Synthesis and preliminary biological evaluation of 9-(4-[18F]-fluoro-3-hydroxymethylbutyl)-guanine ([18F]FHBG) is reported. 9-(4-Hydroxy-3-hydroxymethylbutyl)-guanine (penciclovir) 4 was converted to 9-[N2, O-bis-(methoxytrityl)-3-(tosylmethybutyl)]guanine 7 by treatment with methoxytrityl chloride followed by tosylation. The tosylate 7 was reacted with either tetrabutylammonium fluoride or KF in the presence of kryptofix 2.2.2. to produce the 4-fluoro-N2-O-bis-(methoxytrityl) derivative 8. Removal of the methoxytrityl groups by acidic hydrolysis produced FHBG 5. Radiolabeled product [18F]FHBG was prepared by fluorination of the tosylate 7 with [18F]KF and kryptofix 2.2.2. The labeled product was isolated by HPLC purification on a reverse-phase C18 column, and eluted at 12 min with 15% acetonitrile in water at a flow rate of 2.25 mL/min. Radiochemical yield was 8.0-22.3% with an average of 12% in 7 runs (corrected for decay). Synthesis time was 90 to 100 min including HPLC purification with radiochemical purity >99%, and average specific activity of 320 mCi/micromol. In vitro studies of the compound in HT-29 colon cancer cells revealed 18.2-fold higher uptake into transduced cells compared to control in 3 h. The agent may be useful for imaging viral infection or transfected cells in gene therapy.
