These protease inhibitors prevent viral replication by selectively binding to viral proteases (e.g. HIV-1 protease) and blocking proteolytic cleavage of protein precursors that are necessary for the production of infectious viral particles. Protease inhibitors that have been developed and are currently used in clinical practice include:
Protease inhibitors may be classified either by the type of protease they inhibit, or by their mechanism of action. In 2004 Rawlings and colleagues introduced a classification of protease inhibitors based on similarities detectable at the level of amino acid sequence. [4]
Tipranavir is a nonpeptidic HIV-1 protease inhibitor [11] and reached the market in 2005. [18] Unlike other HIV protease inhibitors on the market, tipranavir was developed from a nonpeptidic coumarin template and its antiprotease activity was discovered by high-throughput screening. [23]
The majority of the sequences having this domain belong to the MEROPS inhibitor family I2, clan IB; the Kunitz/bovine pancreatic trypsin inhibitor family, they inhibit proteases of the S1 family [5] and are restricted to the metazoa with a single exception: Amsacta moorei entomopoxvirus, a species of poxvirus. They are short (about 50 to 60 ...
Protease inhibitor can refer to: Protease inhibitor (pharmacology): a class of medication that inhibits viral protease; Protease inhibitor (biology): molecules that ...
The 3C-like protease inhibitor ensitrelvir received authorization to treat COVID-19 in Japan in 2022. [19] [20] In 2022, an ultralarge virtual screening campaign of 235 million molecules was able to identify a novel broad-spectrum inhibitor targeting the main protease of several coronaviruses. It is unusually not a peptidomimetic. [21]
HIV protease inhibitors work by specifically binding to the active site by mimicking the tetrahedral intermediate of its substrate and essentially becoming “stuck,” disabling the enzyme. After assembly and budding, viral particles lacking active protease cannot mature into infectious virions.
Since MALT1 protease activity is a promising therapeutic target, several different screenings have been performed which have resulted in different types of protease inhibitors. [30] There is active competition between multiple pharma companies and independent research groups in drug development against the MALT1 protease activity.
