Antivirales

<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>

BMS 806 is an antiretroviral agent and is used for the treatment of HIV. It inhibits the fusion of the HIV virus with the host cell membrane.

<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>Valacyclovir is a guanine nucleoside antiviral drug that is used to treat herpes exacerbations. This drug inhibits DNA polymerase and prevents viral DNA synthesis. Valacyclovir is the L-valine ester of acyclovir.</p>

Anti-viral; HIV integrase inhibitor

Anti-viral; capsid inhibitor

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.

HIV-1 integrase inhibitor; inhibits DNA strand transfer

<p>Applications Intermediate in the preparation of Ribavirin.<br></p>

<p>Applications A highly reactive thiol-specific spin-label. A specific conformational probe of thiol site structure by virtue of its minimal rotational freedom and distance from the covalent disulfide linkage to the macromolecule under study.<br></p>

<p>Applications (S)-2-(3-((2-(2-Hydroxypropan-2-yl)thiazol-4-yl)methyl)-3-methylureido)-3-methylbutanoic Acid Methyl Ester is an intermediate in the synthesis of Ritonavir (R535000) derivatives.<br></p>

<p>Applications T-705RMP TEA Salt is a metabolite of T-705RMP (CAS# 356783-08-9), which is a reagent used for the preparation of pyrazine-ribofuranose derivatives as antiviral agents that are useful in the treatment of viral infections. T-705 (Favipiravir) [F103350] gets converted to T-705RMP by host cells, but T-705RMP has little inhibitory effect on the replication of the host cells based on biological studies.<br>References Zhong, B., et al.: Faming Zhuanli Shenqing, 2014:924257 (2014); Yousuke, F., et al.: Antimicrob Agent Chemother., 49, 981 (2005)<br></p>
