Summary
New nucleoside analogs are needed to combat drug-resistant chronic hepatitis B virus (HBV) infection and prevent viral rebound after treatment cessation. This review explores structure-activity relationships of key anti-HBV agents.
Area of Science:
- Hepatology and Virology
- Medicinal Chemistry
- Drug Development
Background:
- Chronic hepatitis B virus (HBV) infection impacts approximately 400 million individuals globally.
- Nucleoside analogs targeting HBV polymerase are crucial for hepatitis B therapy, with lamivudine, adefovir, and entecavir being established treatments.
- Existing therapies face challenges including drug resistance and viral rebound post-treatment, necessitating novel therapeutic strategies.
Purpose of the Study:
- To review the structure-activity relationships (SAR) of significant anti-HBV nucleoside analogs.
- To discuss the latest advancements in the development of novel nucleoside analog therapeutics for HBV infection.
- To address the unmet needs in hepatitis B treatment, focusing on overcoming resistance and preventing viral rebound.
Main Methods:
- Literature review of scientific publications and clinical trial data.
- Analysis of structure-activity relationships for existing and emerging nucleoside analogs.
- Synthesis and evaluation of pharmacological data on anti-HBV nucleoside analogs.
Main Results:
- Detailed examination of SAR for key nucleoside analogs, highlighting molecular features influencing efficacy and resistance profiles.
- Identification of promising new nucleoside analogs with improved potency and reduced resistance potential.
- Overview of recent developments in drug design and medicinal chemistry aimed at enhancing anti-HBV activity.
Conclusions:
- Nucleoside analogs remain a vital class of drugs for managing chronic HBV infection.
- Understanding SAR is critical for designing next-generation analogs that overcome current therapeutic limitations.
- Continued research and development are essential to provide more effective and durable treatments for the global HBV population.

01:10Retrovirus Life Cycles
43.0K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

1.5K
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

01:30Inhibitors of Viral Protein Synthesis
58
Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion...
