摘  要:Recently the Chinese Ministry of Health declared that 93 million people wer.e chronically infected with hepatitis B virus (HBV) in China. Four nucleotide analogues (NAs) are currently approved for the treatment of HBV infection, i.e., lamivudine (LAM), adefovir (ADV), entecavir (ETV), and telbivudine (L-dT). In contrast to therapeutic benefits, prolonged use of NAs increases the emergence of drug-resistant mutations in the HBV reverse transcriptase (RT) domain, leading to a progressive accumulation of NAs-resistant patients. Especially, LAM-refractory patients are prone to develop cross-resistance to other NAs. Novel anti-HBV drugs that are able to deal with the cross-resistance are needed in the clinic. Tenofovir (TDF), which was recently approved in Europe and United States of America, has potential to be such a drug. Clinical trials have proven its high potency for inhibiting HBV replication in HBV-infected patients,Recently the Chinese Ministry of Health declared that 93 million people wer.e chronically infected with hepatitis B virus (HBV) in China.
