Our laboratory focuses on translational research of HIV-1 pathogenesis and mechanisms of virus inhibition by novel class of natural small molecules. We investigated a large number of natural products, and from Sargassum fusiforme we isolated and identified several new inhibitors that block virus during different stages of its replication life cycle. Palmitic acid, which binds to the CD4 receptor and blocks gp120-to-CD4 fusion and HIV-1 entry and infection, is being investigated in preclinical studies towards a microbicide application. Several other molecules are being studied to determine their activity and mechanisms of action.
