Antiviraux

<p>Abacavir is an antiviral nucleoside reverse transcriptase inhibitor that is used for the treatment of HIV. This drug inhibits the activity of HIV-1 reverse transcriptase (RT) both by competing with dGTP and by its incorporation into viral DNA.</p>

<p>CCR-5 chemokine receptor antagonist; inhibits HIV entry via gp120 protein</p>

<p>EIDD 2801 is an orally bioavailable prodrug of β-D-N4-hydroxycytidine and was shown to inhibit SARS-CoV-2 replication in human airway epithelial cells. EIDD 2801 was also tested in mice infected with SARS-CoV and MERS-CoV viruses. EIDD 2801 targets the RNA-dependent RNA polymerase (RdRp) and reduces virus titer and improved pulmonary function in experimental animals when used in prophylactic and therapeutic regime.</p>

<p>Efavirenz is a non-nucleoside-based reverse transcriptase inhibitor (NNRTI) of the reverse transcriptase of HIV-1. It inhibits the viral enzyme reverse transcriptase by binding to its active site. In certain cell culture assays, Efavirenz showed great efficiency when inhibiting wild-type HIV-1 replication. In the treatment of HIV, Efavirenz has been studied in combination with Emtricitabine and Tenofovir disoproxil fumarate for ease of administration in some clinical studies. Recent in vitro cell studies indicated Efavirenz is a potential treatment for pancreatic, prostate and triple-negative breast cancers due to its cytotoxicity against cancer cells.Efavirenz 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>Darunavir is an HIV protease inhibitor that is used in the treatment of HIV-1 infection. This drug inhibits HIV-1 protease from binding and catalyzing by attaching to the enzyme and preventing HIV replication.</p>

<p>BMS 806 is used as an anti-viral agent. It has been shown to inhibit the replication of HIV. BMS 806 inhibits viral life by binding to the surface glycoproteins and inhibiting viral entry into cells. The drug also inhibits viral replication by preventing DNA transcription and translation.</p>

<p>Adefovir is an antiviral drug that is used for the treatment of hepatitis B infections. This drug works by blocking the enzyme reverse transcriptase, therefore preventing the replication of the virus in the body.</p>

<p>**Ivermectin 8α-hydroperoxide** is a derivative of the antiparasitic agent ivermectin, which is synthesized through chemical modification. Ivermectin originally derives from the fermentation products of the bacterium *Streptomyces avermitilis*. The modification to form 8α-hydroperoxide involves the addition of a hydroperoxide group, potentially altering its biological properties.</p>

<p>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.</p>
