Application:
Shanghai Ruifu Chemical Co., Ltd. is the leading manufacturer and supplier of (2S,3S)-1,2-Epoxy-3-(Boc-Amino)-4-Phenylbutane (CAS: 98737-29-2) with high quality, an intermediate typically in the synthesis of Atazanavir (CAS 198904-31-3) and Atazanavir Sulfate (CAS 229975-97-7). Atazanavir is a highly potent HIV-1 protease inhibitor. Has shown to be generally more potent than the five currently approved HIV-1 Prt inhibitors. Atazanavir (BMS-232632) inhibited the proteolytic cleavage of the viral gag precursor p55 polyprotein in a dose-dependent manner, with a EC 50 of approximately 47 nM. Also highly selective for HIV-1 Prt and exhibits cytotoxicity only at concentrations 6,500- to 23,000-fold higher than that required for anti-HIV activity. Atazanavir (BMS-232632) may be an effective HIV-1 inhibitor that may be utilized in a variety of different drug combinations.
