Application:
Shanghai Ruifu Chemical Co., Ltd. is the leading manufacturer and supplier of (2R,3S)-1,2-Epoxy-3-(Boc-Amino)-4-Phenylbutane (CAS 98760-08-8) with high quality, an intermediate of Atazanavir (CAS 198904-31-3) and Atazanavir Sulfate (CAS 229975-97-7). Atazanavir is a novel azapeptide HIV protease inhibitor (PI). Atazanavir is an inhibitor of human immunodeficiency virus type 1 (HIV-1) protease, an enzyme that is essential for the processing of Gag and Gag-Pol polyproteins into structural and enzymatic proteins required for viral replication. It has a similar pharmacophore motif to the other six widely marketed HIV protease inhibitors, most of which are based upon a hydroxyethylamine template. Uniquely, it possesses an aza-peptide motif but maintains many similar pharmacophore elements including lipophilic moieties that presumably bind to S2, S1, S′1, and S′2 positions.
