Non-nucleoside inhibitor of reverse transcriptase; anti-viral

Stability Hygroscopic Applications Tenofovir (T018500) impurity.

Stability Moisture sensitive Applications Chloromethyl Isopropyl Carbonate is an antiviral agent and a Tenofovir (T018500) intermediate. Tenofovir is an acyclic phosphonate nucleotide analogue and reverse transcriptase inhibitor used as an anti-HIV agent. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Mackman, R., et al.: Bioorg. Med. Chem., 15, 5519 (2007), Baudy, R., et al.: J. Med. Chem., 52, 771 (2009),

Ledipasvir D-tartrate is an antiviral compound, which is a direct-acting antiviral agent used in the treatment of hepatitis C virus (HCV) infection. It originates from synthetic sources designed to inhibit the replication of specific viral proteins. Ledipasvir functions by targeting the NS5A protein of the hepatitis C virus, a key component necessary for viral replication. By binding to this protein, Ledipasvir disrupts and inhibits the HCV replication complex, effectively suppressing the viral load in patients. Utilized primarily in the context of chronic hepatitis C treatment, Ledipasvir D-tartrate is typically employed in combination with other antiviral medications, such as sofosbuvir, to enhance therapeutic efficacy. This combination therapy has shown significant success in achieving sustained virologic response in various genotypes of HCV, reducing morbidity and preventing progression to liver-related complications. The use of Ledipasvir D-tartrate in clinical settings underscores its importance in modern antiviral strategies against chronic HCV infection, representing a critical advancement in the management of this pervasive viral disease.

6-Fluoro-3-hydroxypyrazine-2-carboxamide is a potent RNA polymerase inhibitor, active against both RNA viruses in vitro and in vivo. A four-step approach to the synthesis of 6-Fluoro-3-hydroxypyrazine-2-carboxamide was reported in 2014. 6-Fluoro-3-hydroxypyrazine-2-carboxamide is commercialized and has recently been suggested for the treatment of mild cases of COVID-19.

Inhibitor of HIV-1 integrase strand transfer; antiviral
