Embodiment Construction

[0016] The specific implementation of the present invention will be further described below in conjunction with the examples, and the present invention is not limited to the scope of the examples.

[0017] The raw materials used in the following examples can be purchased from the market.

[0018] Experiment 1. In vitro study of the combination of lovastatin and lamivudine in HBV-infected cells

[0019] Purpose:

[0020] To evaluate the inhibitory effect of lovastatin and lamivudine drug combination on HBV infection.

[0021] method:

[0022] In HepG2.2.15 cells, lovastatin (10, 25 μM concentration), lamivudine (10, 50 μM concentration), and different drug concentrations of lovastatin and lamivudine were added to HepG2.15 cells, and after 6 days of culture, The supernatant was collected, the expression of HBeAg antigen was detected by ELISA, and the content of HBV DNA was detected by RT-PCR.

[0023] result:

[0024] from figure 1 It can be seen that compared with lamivud...

Abstract

The invention discloses an application of a nucleotide inhibitor and statins in preparation of a combined medicine for treating HBV infection. The invention also discloses a combined medicine for treating HBV infection, and belongs to the technical field of medicines. The combined medicine can inhibit HBV infection from multiple aspects of HBV replication, virus assembly and budding, the synergistic effect is achieved, and the effect is better.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a combined medicine for treating HBV infection. Background technique [0002] Hepatitis B virus (HBV) infects about 400 million people and is the most common chronic infectious disease worldwide. It is the main cause of primary hepatocellular carcinoma (HCC), and about 1 million people die from HBV infection every year liver failure, cirrhosis and liver cancer. There are currently two classes of approved drugs for the treatment of chronic HBV infection: nucleotide / nucleoside inhibitors and immunomodulators (such as interferon). Nucleotide / nucleoside inhibitors (such as lamivudine, adefovir dipivoxil, entecavir, etc.) mainly inhibit HBV DNA polymerase, thereby preventing virus replication and leading to a decrease in serum viral DNA. However, the HBsAg seroconversion rate of patients after treatment is low, and side effects such as drug-resistant mutations may occu...
