Background:
- HIV-1 integrase (IN) is vital for viral replication, making it a key target for antiviral therapies.
- Human cells lack an equivalent enzyme, enhancing the specificity of IN-targeted drugs.
- Existing HIV-1 integrase strand transfer inhibitors (INSTIs) provide a foundation for new drug development.
Purpose of the Study:
- To review the structural and functional characteristics of HIV-1 IN.
- To analyze the binding interactions of known and investigational INSTIs.
- To identify structural features that correlate with bioactivity for novel inhibitor design.
Main Methods:
- Structural and functional overview of HIV-1 IN.
- Analysis of binding modes for established drugs, clinical candidates, and lead compounds.
- Application of computational clustering techniques to identify structure-activity relationships.

01:30Inhibitors of Viral Protein Synthesis

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...

01:10Retrovirus Life Cycles
50.8K
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...

01:26Size and Structure of Viral Genomes
1.2K
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...
