Entry inhibitors, also known as fusion inhibitors, are a class of antiviral drugs that prevent a virus from entering a cell, for example, by blocking a receptor. Entry inhibitors are used to treat conditions such as HIV and hepatitis D .

Antiviral drugs are a class of antimicrobials, a larger group which also includes antibiotic (also termed antibacterial), antifungal and antiparasitic drugs, [3] or antiviral drugs based on monoclonal antibodies. [4] Most antivirals are considered relatively harmless to the host, and therefore can be used to treat infections.
Leronlimab, the anti-CCR5 monoclonal antibody, can stop HIV from entering the cell and stop viral replication. It prevents the virus-cell binding at a distinct site in the CCR5 co-receptor without interfering with its natural activity. Unlike other entry inhibitors, PRO 140 is a monoclonal antibody.
Particularly, these drugs prevent the cleavage of gag and gag/pol precursor proteins. [16] Virus particles produced in the presence of protease inhibitors are defective and mostly non-infectious. Examples of HIV protease inhibitors are lopinavir, indinavir, nelfinavir, amprenavir and ritonavir.
Drugs that disrupt fusion of virus and target cell are termed entry inhibitors or fusion inhibitors. [citation needed] HIV binds to the host CD4+ cell receptor via the viral protein gp120; gp41, a viral transmembrane protein, then undergoes a conformational change that assists in the fusion of the viral membrane to the host cell membrane ...
If you recently tested positive for COVID-19, you may be eligible for antiviral treatments to help reduce your infection. Earlier this year, when the omicron variant was steering the pandemic ...
Maraviroc is an entry inhibitor.Specifically, maraviroc is a negative allosteric modulator of the CCR5 receptor, which is found on the surface of certain human cells. The chemokine receptor CCR5 is an essential co-receptor for most HIV strains and necessary for the entry process of the virus into the host cell.
