Antivirals

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.

Ritonavir is a HIV protease inhibitor. It has an anti-retroviral activity as it inhibits the protease enzymes specific of both HIV-1 and HIV-2 and has been shown to be effective in controlling virus replication in humans and animals. Ritonavir works by preventing the HIV viral protease enzyme from cleaving the structural and replicative proteins produced by HIV genes such as gag and pol. Ritonavir 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.

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.
