Antivirales

Alamifovir is an antiviral agent, which is synthetically derived. The mode of action of Alamifovir involves the inhibition of viral replication within host cells by targeting specific viral enzymes crucial for the replication process. This interference with the viral life cycle diminishes the ability of the virus to propagate and spread within the host organism. Alamifovir is primarily used in the treatment of viral infections, potentially offering therapeutic benefits for diseases caused by DNA viruses. Its effectiveness is contingent upon its ability to selectively target viral components with minimal cytotoxic effects on host cells, ensuring a beneficial therapeutic index. The applications of Alamifovir in antiviral therapy highlight its relevance in the continuous search for effective treatments against viral pathogens that pose significant clinical challenges. Research into Alamifovir's pharmacokinetics, safety profile, and resistance patterns is ongoing, with the aim of optimizing its use in clinical settings and expanding its utility across a broader spectrum of viral infections.

Darunavir is a HIV-1 protease inhibitor used orally in the treatment of patients with multi-drug resistant HIV-1 infection (Ghosh, 2007). It has also been shown to be effective against other infectious diseases such as hepatitis C virus and SARS coronavirus. Metabolized by cytochrome P450 3A (CYP3A) isoenzymes, darunavir is often administered together with ritonavir that prolongs its bioavaiability, giving a terminal elimination half-life (t1/2) of 15 hours (Back, 2008). The effect of darunavir on natural compounds such as matrix proteins and toll-like receptor activity has also been studied via high performance liquid chromatography (HPLC) experiments.

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. Cytarabine 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. 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.
