HIV-1 integrase (IN) active site inhibitors are the latest class of drugs approved for HIV treatment. The selection of IN strand-transfer drug-resistant HIV strains in patients supports the development of new agents that are active as allosteric IN inhibitors. Here, a docking-based virtual screening has been applied to a small library of natural ligands to identify new allosteric IN inhibitors that target the sucrose binding pocket. From theoretical studies, kuwanon-L emerged as the most promising binder and was thus selected for biological studies. Biochemical studies showed that kuwanon-L is able to inhibit the HIV-1 IN catalytic activity in the absence and in the presence of LEDGF/p75 protein, the IN dimerization, and the IN/LEDGF binding. Kuwanon-L also inhibited HIV-1 replication in cell cultures. Overall, docking and biochemical results suggest that kuwanon-L binds to an allosteric binding pocket and can be considered an attractive lead for the development of new allosteric IN antiviral agents.
