Bottom Line: In recent years, the emergence of numerous useful information of protein-protein interactions (PPI) in the HIV life cycle and related inhibitors makes PPI a new way for antiviral drug intervention.In this study, we identified 26 core human proteins involved in PPI between HIV-1 and host, that have great potential for HIV therapy.In addition, 280 chemicals that interact with three HIV drugs targeting human proteins can also interact with these 26 core proteins.

ABSTRACT
Acquired immune deficiency syndrome (AIDS) is a severe infectious disease that causes a large number of deaths every year. Traditional anti-AIDS drugs directly targeting the HIV-1 encoded enzymes including reverse transcriptase (RT), protease (PR) and integrase (IN) usually suffer from drug resistance after a period of treatment and serious side effects. In recent years, the emergence of numerous useful information of protein-protein interactions (PPI) in the HIV life cycle and related inhibitors makes PPI a new way for antiviral drug intervention. In this study, we identified 26 core human proteins involved in PPI between HIV-1 and host, that have great potential for HIV therapy. In addition, 280 chemicals that interact with three HIV drugs targeting human proteins can also interact with these 26 core proteins. All these indicate that our method as presented in this paper is quite promising. The method may become a useful tool, or at least plays a complementary role to the existing method, for identifying novel anti-HIV drugs.

Mentions: CCR5, a membrane protein, is an important target of anti-HIV therapy as it is one of the major co-receptors for HIV-1infection. There are seven trans-membrane helix structures in CCR5, which formed a “pocket” structure (Fig. 2) [53]. In this “pocket”, aromatic amino acid residuals, hydrophobic amino acid residuals, polar amino acid residuals and hydrophilicity amino acid residuals could bind with chemicals by π-π stacking interaction, hydrophobic interaction, hydrogen bonding interaction and salt-bridge interaction [54], [55], [56], [57].
