protease inhibitors
protease inhibitors is a Protease inhibitor Small molecule drug developed by French National Agency for Research on AIDS and Viral Hepatitis. It is currently FDA-approved for HIV-1 infection (in combination antiretroviral therapy), HIV-1 treatment-experienced patients with protease inhibitor-resistant virus.
Protease inhibitors block the activity of viral proteases, preventing the cleavage of viral polyproteins necessary for viral replication and maturation.
Protease inhibitors are medications that interfere with enzymes that cleave proteins, and they are used to treat conditions such as HIV-1 Infection, AIDS, and Chronic Hepatitis B. They work by selectively binding to viral proteases and blocking proteolytic cleavage of protein precursors necessary for viral replication.

Mechanism of action
Protease inhibitors are a class of antiretroviral drugs that bind to and inhibit HIV protease, an enzyme essential for processing viral proteins during HIV replication. By preventing protease activity, these drugs block the production of mature, infectious viral particles, thereby reducing viral load and slowing disease progression. They are typically used in combination antiretroviral therapy (cART) regimens.
