Antivirals

YM-53403: Antiviral that combats both RSV subgroup A/B, treats respiratory infections.

Rociclovir has antiviral activity and is used to treat viral infections.

Famciclovir is a guanosine analogue antiviral agent that is used for the treatment of various herpesvirus infections, most commonly for herpes zoster. It works by inhibiting the replication of the herpes virus. Famciclovir prevents viral DNA synthesis by inhibiting the viral DNA polymerase and by blocking viral DNA replication. Its active form is penciclovir.

Anti-viral; NS3/4A protease inhibitor

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.

Inhibitor of viral neuraminidase enzyme, effective against influenza A and B viruses. This antiviral compound inhibits neuraminidase-mediated cleavage of host cell sialic acids, which interact with newly synthesised virions from the host cell. This prevents virion budding from the host, resulting in inhibition of virion release and viral infection overall.

Ombitasvir is a NS5A inhibitor antiviral agent with action on hepatitis C virus replication and is used for treating chronic hepatitis C in combination therapies.

Nucleoside reverse transcriptase inhibitor; anti-Hepatitis B virus

HIV-1 Integrase Inhibitor is an antiretroviral compound with a mode of action that blocks the viral enzyme integrase, preventing the integration of viral DNA into the host genome. It is used for the treatment of HIV infection.

Antiviral; nonpeptidic HIV-1 protease inhibitor

Anti-viral; NS5A protein inhibitor

Triazavirin is an antiviral drug developed against SAR-CoV-2. The action of triazavirin might be due to its ability to inhibit the Mpro protease from SARS viruses. Triazavirin has been clinically tested in the treatment of COVID-19 patients.

Cidofovir is an anti-viral agent that is used to treat Cytomegalovirus (CMV) retinitis in patients with AIDS. This drug suppresses CMV replication by inhibiting viral DNA synthesis.

Inhibitor of viral protein NS5B

Abacavir sulfate is an antiviral drug that belongs to the class of HIV protease inhibitors. It is used in combination with other antiretroviral drugs to treat HIV-1 infection. Abacavir sulfate inhibits viral replication by blocking the activity of HIV-1 protease, which is necessary for the production of new virus particles.
Abacavir sulfate is part of our Bio-X ™ Range. These products are aimed at life science researchers who need high quality ready to use products for assay development, screening or other R&D work. With a solubility datasheet and convenient vials, all of our Bio-X ™ products are in stock across our global warehouses for rapid delivery and ease of use.

Etravirine is a non-nucleoside reverse transcriptase inhibitor (NNRTI) medication used in the treatment of human immunodeficiency virus (HIV) infections. It works by blocking reverse transcriptase, an enzyme essential for replication of the virus, thereby preventing the virus from multiplying and spreading. Etravirine is often used in combination with other antiretroviral drugs to effectively treat HIV/AIDS. It is commonly prescribed for patients with virus strains that are resistant to other NNRTI medications due to mutations that confer resistance- mutations K103N and Y181C. Etravirine is a diarylpyrimidine (DAPY) and has conformational isomerism meaning that it binds reverse transcriptase in an fleible manner, under multiple conformations. The impact of specific point mutations in the virus is therefore lessened.

Cytarabine is also known as cytosine arabinoside (ara-C) and is a chemotherapy drug that works by inhibiting DNA synthesis. It acts as a nucleoside analogue, which is incorporated into the growing DNA chain during replication. Cytarabine combines a cytosine base with an arabinose sugar (1β-arabinofuranosylcytosine) and is an analog for human deoxycytosine. Cytarabine interferes with DNA synthesis as it is rapidly converted to cytosine arabinoside triphosphate, damaging DNA when cells are in the synthesis phase (S phase). Tumor cells which are highly mitotic and growing rapidly are therefore preferably targeted. Cytarabine also inhibits nucleotide reductase enzymes as well as nuclear polymerases, leading to interruption and inhibition of synthesis, strand breaks and cell death.

Emtricitabine is an antiviral drug that is used to treat chronic viral hepatitis, which is caused by the hepatitis B and C viruses. The drug blocks the activity of reverse transcriptase, which is an enzyme necessary for the replication of viral RNA in the body. Emtricitabine has been shown to be effective against acute hepatitis B virus infection and chronic hepatitis B virus infection with or without cirrhosis. It also has been shown to be effective against chronic hepatitis C virus infection with or without cirrhosis.
