Benefits of technology

This patent is about a new compound that can be used to treat infections caused by the hepatitis B virus (HBV). The compound has specific chemical properties that make it a potentially effective treatment for HBV. The patent also covers a pharmaceutical composition that contains this compound, as well as a method for using it to prevent or treat HBV infections in humans. The patent also mentions the combination of this compound with other HBV inhibitors.

Problems solved by technology

An effective and well-tolerated vaccine exists, but direct treatment options are currently limited to interferon and the following antivirals; tenofovir, lamivudine, adefovir, entecavir and telbivudine.
Amongst the problems which HBV direct antivirals may encounter are toxicity, mutagenicity, lack of selectivity, poor efficacy, poor bioavailability, and difficulty of synthesis.

Abstract

Inhibitors of HBV replication of formula (I)including stereochemically isomeric forms, and salts, hydrates, solvates thereof, wherein X, R1 to R7 have the meaning as defined herein. The present invention also relates to processes for preparing said compounds, pharmaceutical compositions containing them and their use, alone or in combination with other HBV inhibitors, in HBV therapy.

Description

BACKGROUND ART[0001]The Hepatitis B virus (HBV) is an enveloped, partially double-stranded DNA (dsDNA) virus of the Hepadnavirus family (Hepadnaviridae). Its genome contains 4 overlapping reading frames: the precore / core gene; the polymerase gene; the L, M, and S genes, which encode for the 3 envelope proteins; and the X gene.[0002]Upon infection, the partially double-stranded DNA genome (the relaxed circular DNA; rcDNA) is converted to a covalently closed circular DNA (cccDNA) in the nucleus of the host cell and the viral mRNAs are transcribed. Once encapsidated, the pregenomic RNA (pgRNA), which also codes for core protein and Pol, serves as the template for reverse transcription, which regenerates the partially dsDNA genome (rcDNA) in the nucleocapsid.[0003]HBV has caused epidemics in parts of Asia and Africa, and it is endemic in China. HBV has infected approximately 2 billion people worldwide of which approximately 350 million people have developed chronic infections. The virus...
