Antivíricos

<p>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.</p>

<p>Nucleoside reverse transcriptase inhibitor; anti-Hepatitis B virus</p>

<p>Anti-viral; RNA polymerase inhibitor; sofosbuvir metabolite</p>

<p>GS 5734, also known as remdesivir is a nucleoside prodrug with broad spectrum antiviral activity against RNA viruses. As remdesivir / GS 5734 is a prodrug, it requires to be triphosphorylated by cellular kinases in order to compete with ATP for incorporation in newly replicated viral RNA. A major benefit of remdesivir in comparison with other antiviral nucleoside analogs is its resistance to proofreading exonucleases, which occur in coronaviruses. This means remdesivir can overcome the repair mechanism and preserve its antiviral activity. Remdesivir was reported to have a therapeutic as well as prophylactic efficacy in a mouse model infected with SARS-CoV-1.</p>

<p>Potent inhibitor of viral RNA polymerase called non-structural protein 5B (NS5B). This nucleotide analog is effective against Hepatitis C virus (HCV) infection since it inhibits viral RNA replication. Sofosbuvir is a prodrug and gets triphosphorylated in the liver cells, generating biologically active compound with anti-viral activity.</p>

<p>Zalcitabine (also known as dideoxycytidine or ddC) is a nucleoside analogue reverse transcriptase inhibitor (NRTI) medication used in the treatment of human immunodeficiency virus (HIV) infections. It works by blocking reverse transcriptase, an enzyme essential for replication of the HIV virus, thereby preventing the virus from multiplying and spreading. Zalcitabine is often used in combination with other antiretroviral drugs to effectively treat HIV/AIDS.</p>

<p>Anti-viral; HIV protease inhibitor</p>

<p>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.</p>

<p>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.</p>

<p>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.</p>

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

<p>Anti-viral; inhibitor of cytomegalovirus-terminase complex</p>

<p>N-Boc-protected -Guanidino Oseltamivir is a fine chemical that belongs to the group of versatile building blocks. It is a complex compound that has been used in research as a reagent and speciality chemical. N-Boc-protected -Guanidino Oseltamivir is an important intermediate for the synthesis of a variety of useful compounds, such as pharmaceuticals and natural products. This compound is also used as a reaction component in organic syntheses, especially for the preparation of high quality and useful scaffolds.</p>

<p>Anti-viral; NS3/4A protease inhibitor</p>

<p>Antiviral; nonpeptidic HIV-1 protease inhibitor</p>

<p>A compound with antiviral activity against Ebola virus that targets the surface-exposed glycoprotein and inhibits viral entry into host cells. In vitro studies in Vero cells revealed the compound inhibits the viral replication with EC50 of 0.38 µM.</p>

<p>Dasabuvir is a non-nucleoside NS5B polymerase inhibitor with action on hepatitis C virus RNA replication and is used for treating hepatitis C in combination therapies.</p>

<p>Potent and selective inhibitor of influenza A and B sialidases. Zanamivir belongs to the class of drugs known as neuraminidase inhibitors. This compound is a sialic acid analogue that occupies viral neuraminidase active site, inhibits enzyme’s hydrolytic activity and cleavage of sialic acid residues from host cell surface glycans. It therefore prevents shedding newly produced virions from infected cell surface and reduces infection of surrounding cells. In in vitro studies with influenza A and B virus isolates, zanamivir inhibited the plaque formation by 50% in canine cells (MDCK) with concentrations between 0.004 and 0.014 μM and 0.02 and 16 μM, respectively.<br>Zanamivir hydrate is part of our Bio-X ™ Range.

<p>Dapivirine is a non-nucleoside reverse transcriptase inhibitor with action on HIV-1 reverse transcriptase and is used for preventing HIV infection through vaginal rings.</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.
