Abstract

A series of amino acid prodrugs of NVR3-778, a potent anti-HBV candidate currently under phase II clinical trial, were designed and synthesized as new anti-HBV agents. Except for 1e, all of them displayed roughly comparable anti-HBV activity (IC50, 0.28-0.56 µM) to NVR3-778 (IC50, 0.26 µM). Compound 1a, a l-valine ester prodrug of NVR3-778, was found to show significantly improved water solubility (0.7 mg/mL, pH 2) as we expected, and lower cytotoxicity (CC50 > 10 µM) than NVR3-778 (CC50, 4.81 µM). Moreover, 1a also exhibited acceptable PK properties and comparable in vivo efficacy in HBV DNA hydrodynamic mouse model to that of NVR3-778, suggesting it may serve as a promising lead compound for further anti-HBV drug discovery.
