Amprenavir-d₄ is intended for use as an internal standard for the quantification of amprenavir by GC- or LC-MS. Amprenavir is an inhibitor of HIV protease (K_i = 0.04 nM).¹ It inhibits the cytopathic effects of HIV-1 in MT-4 cells (IC₅₀ = 150 nM). Formulations containing amprenavir have been used in combination with other antiretroviral agents in the treatment of HIV-1 infection.
