Inhibitors of human immunodeficiency virus integrase

Abstract

Integration of the viral DNA into a host cell chromosome is an essential step for HIV replication and maintenance of persistent infection. Two viral factors are essential for integration: the viral DNA termini (the att sites) and IN. Accruing knowledge of the IN structure, catalytic mechanisms, and interactions with other proteins can be used to design strategies to block integration. A large number of inhibitors have been identified that can be used as leads for the development of potent and selective anti-IN drugs with antiviral activity.
