Abstract/OtherAbstract:
In recent years HIV-1 integrase (IN), has emerged as an attractive target for novel anti-AIDS agents. In particular nonactive-site-binding IN inhibitors would display synergy with current strand-transfer-specific IN inhibitors and other antiretroviral drugs in clinical use. An effective allosteric inhibitory approach would be the disruption of protein-protein interaction (PPI) between IN and cellular cofactors, such as LEDGF/p75. To date, several small molecules have been reported to be inhibitors of the PPI between IN and LEDGF/p75. In this study, we investigated the most relevant interactions between five selected PPI inhibitors and IN comparing them to the naturally occurring IN-LEDGF/p75 complex. We calculated the binding free energies by using the method of molecular mechanics-generalized born surface area (MM-GBSA). Total energy was decomposed on per-residue contribution, and hydrogen bond occupancies were monitored throughout the simulations. Considering all these results we obtained a good correlation with experimental activity and useful insights for the development of new inhibitors.
