Fosamprenavir is an orally active inhibitor targeting HIV-1 protease and is a prodrug of Amprenavir (HY-17430). Fosamprenavir is hydrolyzed into Amprenavir (VX-478) by cell phosphatases in the intestinal epithelium. Amprenavir binds to the active site of HIV-1 protease, preventing the processing of viral gag and gag-pol polyprotein precursors, thereby inhibiting the formation of mature infectious virus particles and exerting anti-HIV-1 infection activity. Fosamprenavir can be used for the study of human immunodeficiency virus (HIV-1) infection.

Rosamultin is a 19 α-hydroxyursane-type triterpenoid isolated from Potentilla anserina?L. Rosamultin has inhibitory effects against HIV-1 protease. Rosamultin has the potential for treating H₂O₂-induced oxidative stress injury through its antioxidant and antiapoptosis effects.

ddCTP trilithium solution (100 mM) is a chain-terminating dideoxynucleotide. ddCTP trilithium is a type of chain-terminating deoxynucleotide. ddCTP trilithium can be incorporated into the extension primer chain that lacks the 3'-hydroxyl group, thereby terminating primer extension, viral genome replication, and DNA synthesis. ddCTP trilithium can distinguish almost identical RNA through distinguishable extension products in primer extension inhibition experiments. ddCTP trilithium is the active metabolite of Zalcitabine (HY-17392), which can competitively inhibit HIV reverse transcriptase, terminate the synthesis of viral DNA chains, and thereby inhibit HIV replication.

Indinavir (MK-639 free base) is an orally active and selective HIV-1 protease inhibitor with a K_i of 0.54 nM for PR. Indinavir exhibits anticancer activity by inhibiting the activation of MMPs-2 hydrolysis, anti-angiogenesis and inducing apoptosis. Indinavir is also a SARS-CoV 3CL^pro inhibitor.
