Identification of Anti-HIV Compounds Inhibiting Virus Assembly and Binding of Nucleocapsid Protein to Nucleic Acid
Description of Invention:
The subject invention identified two groups of active anti-viral compounds. The first group comprises aromatic, antimony-containing compounds, while the second group comprises aromatic tricarboxylic acid. Both groups were shown to inhibit viral particle assembly and inhibit the binding of nucleocapsid protein to nucleic acid. Recently, the first group also demonstrated the capability of blocking HIV-1 viral entry into CD4+ cells through binding to CD4 and inhibiting gp120-CD4 interaction, and they are well tolerated in vivo. Hence, these compounds are potent inhibitors of HIV and act via a novel mechanism, ideal for developing a new generation of anti-HIV medicine.
Applications:
HIV treatment and prevention
Development Status: In vivo preclinical data available, including data from efficacy, pharmacokinetics and preliminary toxicity studies.
