Biological Activity

Non-nucleoside reverse transcriptase inhibitor (NNRTI). Selectively inhibits HIV-1 reverse transcriptase (RNA-dependent DNA polymerase) over other cellular polymerases (IC50 values are 0.26, 440 and >550 μM for HIV-1 reverse transcriptase, DNA polymerase α and DNA polymerase δ). Prevents HIV-1 spread in vivo and blocks viral replication in peripheral blood lymphocytes. Orally active.

Licensing Information
