Ledipasvir D-tartrate is an antiviral compound, which is a direct-acting antiviral agent used in the treatment of hepatitis C virus (HCV) infection. It originates from synthetic sources designed to inhibit the replication of specific viral proteins. Ledipasvir functions by targeting the NS5A protein of the hepatitis C virus, a key component necessary for viral replication. By binding to this protein, Ledipasvir disrupts and inhibits the HCV replication complex, effectively suppressing the viral load in patients.

Etravirine is a non-nucleoside reverse transcriptase inhibitor (NNRTI) medication used in the treatment of human immunodeficiency virus (HIV) infections. It works by blocking reverse transcriptase, an enzyme essential for replication of the virus, thereby preventing the virus from multiplying and spreading. Etravirine is often used in combination with other antiretroviral drugs to effectively treat HIV/AIDS. It is commonly prescribed for patients with virus strains that are resistant to other NNRTI medications due to mutations that confer resistance- mutations K103N and Y181C. Etravirine is a diarylpyrimidine (DAPY) and has conformational isomerism meaning that it binds reverse transcriptase in an fleible manner, under multiple conformations. The impact of specific point mutations in the virus is therefore lessened.

Inhibitor of viral protein NS5B

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.

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.

Stavudine works by inhibiting viral replication by preventing the incorporation of viral dNTPs into the growing DNA chain, thus blocking DNA synthesis.

Viramidine is a nucleotide analogue prodrug, which is derived from naturally occurring nucleosides, specifically optimized for enhanced therapeutic profiles. Its mode of action involves conversion into ribavirin triphosphate within the body. This active form inhibits viral RNA polymerase, a critical enzyme necessary for viral replication. By disrupting the synthesis of viral RNA, Viramidine effectively reduces viral proliferation within host cells.

Ombitasvir is a NS5A inhibitor antiviral agent with action on hepatitis C virus replication and is used for treating chronic hepatitis C in combination therapies.

Inhibitor of viral neuraminidase enzyme, effective against influenza A and B viruses. This antiviral compound inhibits neuraminidase-mediated cleavage of host cell sialic acids, which interact with newly synthesised virions from the host cell. This prevents virion budding from the host, resulting in inhibition of virion release and viral infection overall.

Atazanavir is a HIV-1 protease inhibitor, used in the anti-retroviral therapy of adult and sometimes paediatric patients infected with HIV. In in vitro studies with human pulmonary epithelial cells, atazanavir has been studied as a potential inhibitor of SARS-CoV-2 Mpro protease, with the aim of halting viral replication.

Triazavirin is an antiviral drug developed against SAR-CoV-2. The action of triazavirin might be due to its ability to inhibit the Mpro protease from SARS viruses. Triazavirin has been clinically tested in the treatment of COVID-19 patients.

Tenofovir diphosphate is an antiviral compound, which is a key active metabolite derived from the prodrugs tenofovir disoproxil fumarate and tenofovir alafenamide, both originating from chemical synthesis. Its mode of action involves inhibiting the activity of HIV-1 reverse transcriptase by competing with the natural substrate, deoxyadenosine 5’-triphosphate, and causing chain termination after incorporation into viral DNA. This mechanism effectively prevents the replication of retroviral DNA, thus halting the progression of the infection.

Tromantadine hydrochloride is a synthetic antiviral compound, which is a derivative of adamantane. It originates from chemical synthesis, tailored specifically to target viral processes. Tromantadine hydrochloride primarily exerts its effects by inhibiting the penetration of virus particles into host cells and impeding the subsequent stages of viral replication. This mode of action effectively reduces the viral load and hinders the progression of the infection.

Abacavir sulfate is a pharmaceutical compound classified as a nucleoside reverse transcriptase inhibitor (NRTI), which is derived from synthetic sources. Its mode of action involves the inhibition of the reverse transcriptase enzyme, essential for the replication of HIV.
