An internal standard for the quantification of saquinavir
Sauinavir-d9 is intended for use as an internal standard for the quantification of saquinavir by GC- or LC-MS. Saquinavir is an HIV protease inhibitor (Kis = 0.12 and <0.1 nM for HIV-1 and HIV-2 protease, respectively) that exhibits antiviral activity with low cytotoxicity.1,2 When co-administered with ritonavir , the bioavailability of saquinavir (20 mg/kg) has been shown to increase 325-fold in mice through a mechanism that inhibits its metabolism by CYP3A.3
