ChEBI: Phosphoric acid in which one of the hydroxy groups is replaced by a carboxylic acid group. It is used as the trisodium salt as an antiviral agent in the treatment of cytomegalovirus retinitis (CMV retinitis, an inflamation of the retina that can lead to bl ndness) and as an alternative to ganciclovir for AIDS patients who require concurrent antiretroviral therapy but are unable to tolerate ganciclovir due to haematological toxicity.

Phosphonoformic acid is phosphoric acid in which one of the hydroxy groups is replaced by a carboxylic acid group. It is used as the trisodium salt as an antiviral agent in the treatment of cytomegalovirus retinitis (CMV retinitis, an inflamation of the retina that can lead to blindness) and as an alternative to ganciclovir for AIDS patients who require concurrent antiretroviral therapy but are unable to tolerate ganciclovir due to haematological toxicity. It has a role as an antiviral drug, a sodium-dependent Pi-transporter inhibitor, a HIV-1 reverse transcriptase inhibitor and a geroprotector. It is a one-carbon compound, a member of phosphonic acids and a carboxylic acid. It derives from a phosphonic acid and a formic acid. It is a conjugate acid of a phosphonatoformate and a phosphonoformate(2-).|An antiviral agent used in the treatment of cytomegalovirus retinitis. Foscarnet also shows activity against human herpes viruses and HIV.|Foscarnet is a Pyrophosphate Analog DNA Polymerase Inhibitor. The mechanism of action of foscarnet is as a DNA Polymerase Inhibitor, and Chelating Activity.|Foscarnet a simple pyrophosphate molecule which has antiviral activity against many viruses and is used intravenously in therapy of serious cytomegalovirus infections, largely in immunocompromised patients. Foscarnet has been associated with mild-to-moderate serum aminotransferase elevations during intravenous therapy, but not with episodes of clinically apparent liver injury.|Foscarnet is a synthetic organic analog of inorganic pyrophosphate with activity against several types of viruses, but primarily used for the treatment of cytomegalovirus retinitis. Foscarnet selectively blocks the pyrophosphate binding site of virus-specific DNA polymerases at concentrations that do not affect cellular DNA polymerases. Because this agent crosses the blood brain barrier, it may be used in the treatment of viral infections of the central nervous system.|An antiviral agent used in the treatment of cytomegalovirus retinitis.
