Area of Science:

  • Virology and Antiviral Drug Discovery
  • Molecular Biology of Viral Entry

Background:

  • The replication cycle of human immunodeficiency virus (HIV) involves critical initial steps of virus adsorption and fusion with host cells.
  • These early events are mediated by interactions between viral envelope glycoproteins (gp 120) and cellular receptors (CD4, CXCR4).

Purpose of the Study:

  • To explore the potential of metal-binding compounds as antiviral agents targeting HIV entry.
  • To investigate the mechanisms by which specific compounds interfere with HIV adsorption and fusion processes.

Main Methods:

  • Investigating the effects of polyanionic compounds (polysulfates, polysulfonates, polycarboxylates, polyoxometalates, sulfonated/carboxylated metalloporphyrins), bicyclams, and G-octet-forming oligonucleotides.
  • Analyzing the interference of these compounds with the interaction between viral gp 120 glycoproteins and cellular CD4/CXCR4 receptors.

Main Results:

  • Metal-binding compounds demonstrate potential as inhibitors of initial HIV infection events.
  • The study focuses on understanding how these compounds disrupt the gp 120-CD4/CXCR4 binding crucial for viral entry.

Conclusions:

  • Metal-binding compounds represent a promising class of antivirals targeting HIV adsorption and fusion.
  • Further elucidation of their molecular interactions with viral and cellular components is warranted for therapeutic development.
