Abstract
Currently, clinically approved nucleos (t) ide analogs (NAs) are very efficient in reducing the load of hepatitis B virus (HBV) with minimum side effects. Chronic hepatitis B (CHB) is one of the major causes of morbidity and mortality worldwide. However, the long-term administration of antiviral drugs promotes HBV for potential drug resistance. Herein, 2'-fluoro-6'-methylene carbocyclic adenosine (FMCA) and its phosphoramidate (FMCAP) have been discovered, which may be utilized in combination with therapies for curing drug-resistant chronic hepatitis B. In preclinical studies, these carbocyclic NAs demonstrated potential anti-HBV activity against adefovir, as well as lamivudine (LMV / LAM) drug-resistant mutants. In vitro, these peptides have demonstrated significant activity against LMV / ent Preliminary studies of FMCA / FMCAP in chimeric mice and female Non-obese diabetic / severe combined immunodeficiency (NOD / SCID) mouse models having the LMV / ETV triple mutant shown a high rate of reduction of HBV DNA levels compared to ETV. In this review, we have summarized preclinical studies of FMCA and its phosphoramidate prodrug (FMCAP).
