Application:

Methyl (S)-2-(Boc-amino)-3-[(S)-2-oxo-3-pyrrolidinyl]propanoate (CAS 328086-60-8) is the intermediate of PF-07321332 Paxlovid (CAS 2628280-40-8) and Boceprevir (CAS 394730-60-0). PF-07321332, the key component of Paxlovid (PF-07321332 and Ritonavir) which is an investigational COVID-19 oral antiviral candidate, is an orally bioavailable 3C-like protease (3CLPRO) inhibitor with potent antiviral effects against SARS-CoV-2 virus and COVID-19. On Nove 6th 2021, Pfizer announced that Paxlovid significantly reduced hospitalization and death, based on an interim analysis of the Phase 2/3 EPIC-HR (Evaluation of Protease Inhibition for COVID-19 in High-Risk Patients) randomized, double-blind study of non-hospitalized adult patients with COVID-19, who are at high risk of progressing to severe illness. Boceprevir (EBP-520) is an HCV protease inhibitor (Ki=14 nM) for the treatment of hepatitis C virus infection. Boceprevir with pegylated interferon and ribavirin (PegIFN/RBV) enabled improvement in sustained virological response rates of patients with genotype 1 HCV. Boceprevir interacts with immunosuppressive therapy (IT) by inhibiting the cytochrome P450 3A enzyme.
