Integrase

Retroviral integration is promoted by the viral integrase (IN) enzyme, which enters the cell as a component of the virion particle. Integrase enables retrovirus genetic material to be integrated into the host chromosome. It is essential to retrovirus replication. Integrase catalyzes two spatially and temporally distinct reactions within the context of the preintegration complex (PIC), a large structure derived from the virus core. The integrase inhibitors provide a novel target for antiretroviral therapy.

S2005 Raltegravir Raltegravir is a potent integrase (IN) inhibitor for WT and S217Q PFV IN with IC50 of 90 nM and 40 nM in cell-free assays, respectively. It shows greater than 1000-fold selectivity for HIV-1 IN over several related Mg2+-dependent enzyme such as HCV polymerase, HIV reverse transcriptase, HIV RNaseH and human α-, β-, γ-polymerases.
