Subviral Agents

452
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...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

49.1K
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...

Retroviruses

14.5K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Summary

Quinolines are crucial in developing HIV integrase inhibitors, offering a privileged scaffold for new drug discovery. This review explores their structural advantages for creating effective HIV treatments.

Area of Science:

  • Medicinal Chemistry
  • Virology
  • Drug Discovery

Background:

  • HIV integrase is a key target for antiretroviral therapy.
  • Drug development was slow due to assay and structural limitations.
  • The first integrase inhibitor, raltegravir, emerged in 2007, followed by numerous others.

Purpose of the Study:

  • To review quinoline-based compounds as HIV integrase inhibitors.
  • To investigate if the quinoline scaffold is privileged for this activity.
  • To identify structural features contributing to their efficacy.

Main Methods:

  • Literature review of quinoline derivatives targeting HIV integrase.
  • Analysis of structure-activity relationships.
  • Examination of published structural and biological data.
