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. By incorporating itself into the viral DNA chain during replication, Abacavir effectively halts the process, preventing further multiplication of the virus within the host cells. This antiretroviral medication is primarily used in the management and treatment of human immunodeficiency virus (HIV-1) infections. Abacavir sulfate is a critical component in highly active antiretroviral therapy (HAART), contributing to the reduction of viral load, enhancing immune function, and improving the long-term clinical outcomes in patients living with HIV. Its application in combination therapies has been instrumental in transforming HIV from a fatal disease into a manageable chronic condition.

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.

Galidesivir dihydrochloride is an investigational antiviral drug, which is a synthetic nucleoside analogue with broad-spectrum activity. It is derived from a modified adenosine analog structure, targeting viral RNA-dependent RNA polymerases. Galidesivir functions through the incorporation into viral RNA, leading to premature termination of RNA synthesis, effectively inhibiting viral replication. This mechanism aligns with its utility in combating various RNA viruses. The primary applications of Galidesivir dihydrochloride are in the treatment of viral infections caused by viruses such as Ebola, Marburg, and potentially other emerging viral pathogens. Research has shown promise in its capacity to limit viral proliferation, which is crucial in both therapeutic and pandemic preparedness contexts. The compound’s versatility against diverse viral targets makes it a significant subject of ongoing research in virology and pharmacology, with potential implications for public health interventions against viral epidemics.
