An HIV protease inhibitor which acts as an analog of an HIV protease cleavage site. It is a highly specific inhibitor of HIV-1 and HIV-2 proteases, and also inhibits CYTOCHROME P-450 CYP3A. There was some evidence of in vitro activity against SARS-CoV-2, but no clinical trial data was found to support use in the treatment of COVID-19.
