HIV-2 Infection

NSC727447 is a vinyl urea-based allosteric inhibitor of HIV reverse transcriptase-associated RNase H with IC₅₀ values of 2.0 μM and 2.5 μM against HIV-1 and HIV-2 RNase H, respectively, and IC₅₀ values of 100 μM and 10.6 μM against Escherichia coli and human RNase H, respectively. NSC727447 exerts allosteric inhibitory effects mainly by interacting with the region adjacent to α-helix I in the thumb subdomain of the p51 subunit of HIV-1 reverse transcriptase. Cys280, Lys281 and the RNase H primer grip region are involved in its action, and it may inhibit the catalytic activity of RNase H by altering the positioning of nucleic acid substrates or the geometry of the RNase H active site. NSC727447 can be used in studies related to HIV infection, the function of HIV reverse transcriptase RNase H, and allosteric inhibition mechanisms.

INDOPY-1 (Indolopyridone-1) is a selective, reversible, and competitive HIV-1 reverse transcriptase inhibitor. INDOPY-1 reversibly binds to the active site of reverse transcriptase. INDOPY-1 inhibits DNA synthesis. INDOPY-1 exhibits antiviral activity against various retroviruses, including HIV-1 IIIB, HIV-1 HXB2 K103N Y181C, HIV-2 ROD, and SIV Mac251. INDOPY-1 can be used in the research of immunodeficiency virus infection.
