Mechanism of Action |
The HIV lifecycle is comprised of 3 distinct stages: assembly, involving creation and packaging of essential viral components; budding, wherein the viral particle crosses the host cell plasma membrane and forms a lipid envelope; and maturation, wherein the viral particle alters its structure and becomes infectious. At the center of this lifecycle is the Gag polyprotein which, along with the products of its proteolysis, coordinate these stages and function as the major structural proteins of the virus. The HIV-1 protease enzyme, a dimeric aspartic protease, is the enzyme responsible for cleaving the Gag polyprotein and thus plays a critical role in many aspects of the HIV viral lifecycle. Saquinavir is an inhibitor of the HIV-1 protease enzyme. Its design is based on the "peptidomimetic" principle, wherein the molecule contains a hydroxyethylene scaffold that mimics the normal peptide linkage (cleaved by HIV protease) but which itself cannot be cleaved. By preventing HIV-1 protease activity, and thus the proteolysis of the Gag polyprotein, saquinavir results in the production of immature, non-infectious viral particles., While the complete mechanisms of antiviral activity of saquinavir have not been fully elucidated, saquinavir apparently inhibits replication of retroviruses, including human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2), by interfering with HIV protease. The drug, therefore, exerts a virustatic effect against retroviruses by acting as an HIV protease inhibitor., Saquinavir is a selective, competitive, reversible inhibitor of HIV protease. HIV protease, an aspartic endopeptidase that functions as a homodimer, plays an essential role in the replication cycle of HIV and the formation of infectious virus. During HIV replication, HIV protease cleaves viral polypeptide products of the gag and gag-pol genes (i.e., p55 and p160) to form structural proteins of the virion core (i.e., p17, p24, p9, and p7) and essential viral enzymes (i.e., reverse transcriptase, integrase, and protease). Because saquinavir is a structural analog of the HIV Phe-Pro protease cleavage site, the drug inhibits the function of the enzyme. By interfering with the formation of these essential proteins and enzymes, saquinavir blocks maturation of the virus and causes the formation of nonfunctional, immature, noninfectious virions. Saquinavir is active in both acutely and chronically infected cells since it targets the HIV replication cycle after translation and before assembly. Thus, the drug is active in chronically infected cells (e.g., monocytes and macrophages) that generally are not affected by nucleoside reverse transcriptase inhibitors (e.g., didanosine, lamivudine, stavudine, zalcitabine, zidovudine). Saquinavir does not affect early stages of the HIV replication cycle; however, the drug interferes with the production of infectious HIV and limits further infectious spread of the virus., Unlike nucleoside antiretroviral agents, the antiviral activity of saquinavir does not depend on intracellular conversion to an active metabolite. Saquinavir and other HIV protease inhibitors (e.g., amprenavir, indinavir, lopinavir, nelfinavir, ritonavir) act at a different stage of the HIV replication cycle than nucleoside and nonnucleoside reverse transcriptase inhibitors, and results of in vitro studies indicate that the antiretroviral effects of some nucleoside reverse transcriptase inhibitors and HIV protease inhibitors may be additive or synergistic. | |
