Development of an AlphaScreen-based HIV-1 integrase dimerization assay for discovery of novel allosteric inhibitors

摘要

Abstract: In recent years, HIV-1 integrase (IN) has become an established target in the field of antiretroviral drug discovery. However, its sole clinically approved inhibitor, the integrase strand transfer inhibitor (INSTI) raltegravir, has a surprisingly low genetic barrier for resistance. Furthermore, the only two other integrase inhibitors currently in advanced clinical trials, elvitegravir and dolutegravir, share its mechanism of action and certain resistance pathways.
