<p>Anti-viral; NS5A protein inhibitor</p>

<p>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.</p>

<p>Baloxavir marboxil is a selective inhibitor of the cap-dependent endonuclease of RNA polymerase, an acidic protein in influenza A and B viruses. In patients, baloxavir marboxil reduces the time to recovery by alleviating the symptoms of the influenza A and B infection, in both adults and children.</p>

<p>Anti-viral; non-nucleoside reverse transcriptase inhibitor</p>

<p>Tenofovir is an acyclic nucleoside phosphonate that exhibits anti-viral properties through its inhibition of reverse transcriptases. In particular, Tenofovir is a potent inhibitor of Human Immunodeficiency Virus (HIV) and chronic Hepatitis B Virus (HBV) reverse transcriptases, thus preventing the replication of genetic viral material. This property is beneficial in virus research areas and developing antiviral treatments. Once inside the body tenofovir is metabolized into its active form, tenofovir diphosphate, by the lysosomal protease cathepsin A, nucleotide kinases and adenylate kinases. <br>Tenofovir 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&amp;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.</p>

<p>Lamivudine (commonly called 3TC) is a potent nucleoside analogue reverse transcriptase inhibitor. It is one of the front line treatments for HIV.  It is an analogue of cytidine, and can inhibit both types (1 and 2) of HIV reverse transcriptase as well as the reverse transcriptase of hepatitis B. It needs to be phosphorylated to its triphosphate form before it is active.</p>

<p>Raltegravir is an antiretroviral agent that is used for the treatment of HIV infections. It inhibits HIV integrase in order to prevent viral genome from being inserted into the human genome. It binds to the active site of the enzyme and prevents it from binding to a target sequence on the viral DNA. This drug is metabolized by glucuronidation.</p>

<p>Inhibitor of hepatitis C viral enzyme NS3-4A serine protease</p>

<p>Inhibitor of viral protein NS5B</p>

<p>Pimodivir is a non-nucleoside-derived inhibitor of the polymerase basic protein 2 (PB2) subunit found in the polymerase complex of the influenza A virus. In general, pimodivir is indicated for the treatment of patients with severe influenza although knowledge about possible rise of resistance is not available.</p>

<p>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.</p>

<p>Galidesivir dihydrochloride is an investigational antiviral drug, which is a synthetic nucleoside analogue with broad-spectrum activity. It is derived from a modified adenosine analog structure, targeting viral RNA-dependent RNA polymerases. Galidesivir functions through the incorporation into viral RNA, leading to premature termination of RNA synthesis, effectively inhibiting viral replication. This mechanism aligns with its utility in combating various RNA viruses.</p>

<p>Emtricitabine is a nucleoside analog that is an antiviral drug used to treat HIV/AIDS. It is a synthetic nucleoside analog of cytidine, in which the 3' phosphate and 5' hydroxyl groups have been replaced with a fluorine atom and a methoxy group, respectively. Emtricitabine has been shown to inhibit the synthesis of viral DNA by competing for incorporation into the viral DNA strand during the elongation phase of viral replication. Emtricitabine also has anticancer activity, but no other known therapeutic uses.</p>

<p>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.</p>

<p>Tenofovir diphosphate triethylamine (mixture of diastereomers) is an antiviral compound, which is a synthetic chemical product derived from the parent compound, tenofovir. This formulation includes a mixture of diastereomers to enhance its solubility and bioavailability. The compound primarily functions as a nucleotide reverse transcriptase inhibitor (NRTI). It targets viral reverse transcriptase enzymes, inhibiting DNA synthesis and subsequent viral replication by causing premature chain termination.</p>

<p>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.</p>
