Description

Technical Field

[0001] This invention relates to the field of biomedicine, specifically to a class of amide compounds for the treatment and / or prevention of hepatitis virus infection, their preparation methods and applications, which can effectively inhibit HBV virus replication and reduce HBV surface antigen (HBsAg). Background Technology

[0002] Hepatitis B virus (HBV) is an enveloped DNA virus belonging to the Hepadnaviridae family. Chronic hepatitis B (CHB) can progress to serious liver diseases such as liver fibrosis, cirrhosis, liver failure, and hepatocellular carcinoma (HCC). The World Health Organization estimates that 2 billion people worldwide have been infected with HBV, with approximately 300 million chronically infected individuals. Around 1.5 million new infections occur annually, and approximately 1 million people die each year from liver diseases caused by HBV infection. Chronic hepatitis B remains a serious global disease threatening human health. Although current treatments can suppress HBV replication and reduce liver damage, they cannot eliminate HBV or achieve a clinical cure.

[0003] Therefore, novel or improved drugs and treatments remain in urgent clinical need. Summary of the Invention

[0004] This invention provides a class of compounds that can effectively inhibit HBV virus replication and suppress HBsAg secretion in HBV-infected cells. Compared to similar compounds known in the art, the compounds of this invention exhibit higher activity, higher selectivity, better in vivo efficacy, better safety, superior pharmacokinetic properties, and better druggability.

[0005] The present invention also provides pharmaceutical compositions containing the said compound and methods of using the compound or composition to inhibit HBV replication and / or treat diseases related to or caused by HBV.

[0006] In a first aspect, the present invention provides a compound, or a pharmaceutically acceptable salt, stereoisomer, solvate, isotopically labeled compound, metabolite, or prodrug thereof, said compound having the structure shown in Formula A:

They may contain opacifying agents, and the release of the active compound or compound from such compositions can be delayed in a portion of the digestive tract. Examples of encapsulating components that can be used are polymeric substances and waxes. If necessary, the active compound may also be formed into microcapsules with one or more of the excipients described above.

[0186] Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, or tinctures.
