Protease inhibitors are used to treat HIV, Hep C etc along with other drugs. These drugs act as a scissor to cut the polypeptides that are produced by the translation of the viral RNA, thus stopping the viral replication.
There are so many of them currently in existence.. eg atazanavir, lopinavir, ritonavir etc
But these do have side-effects and also several drug interactions - even with the commonly used statins.
