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.

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. 
Tenofovir 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.

Inhibitor of DNA replication; inhibitor of theophylline and caffeine metabolism

Griseofulvin is an antifungal drug used to treat several types of dermatophytosis (ringworm). This includes fungal infections of the nails, scalp and the skin when antifungal creams have not worked. It is suggested that it prevents nuclear acid production and fungal cell mitosis. Additionally, through binding to alpha and beta tubulin, it interferes with the function of the spindle and cytoplasmic microtubules.

Moxalactam Sodium Salt (Mixture of diastereomers) is an oxacephem antibiotic with action on bacterial cell wall synthesis and is used for treating infections caused by gram-negative bacteria like Escherichia coli and Pseudomonas aeruginosa

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.

Anti-viral; inhibitor of cytomegalovirus-terminase complex

Bacitracin is a polypeptide antibiotic and is used for the treatment of bacterial infections, particularly skin infections. It interferes with bacterial cell wall synthesis by inhibiting the dephosphorylation of bactoprenol.

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.
