NSC727447
Based on 1 Customer Validation
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.

NSC727447 inhibits the RT-associated RNase H activities of HIV-1 and HIV-2 with IC50 values of 2.0 μM and 2.5 μM, respectively, while its IC50 values against E. coli and human RNase H are 100 μM and 10.6 μM, respectively[1].
NSC727447 (50 μM) does not inhibit the RNA-dependent DNA polymerase and pyrophosphorolysis activities of HIV-1 RT, demonstrating preferential inhibitory activity against RNase H function[1].
NSC727447 (0-16 μM) exhibits mutually exclusive inhibition with α-thujaplicinol, an active-site RNase H inhibitor, suggesting that NSC727447 modulates RNase H activity via a mechanism distinct from direct metal chelation[1].
NSC727447 (37 °C; 10 min) inhibits wild-type HIV-1 RT RNase H activity with an IC50 of 1.20 μM, while the p51 thumb C280A mutation reduces its inhibitory sensitivity by approximately 3-fold, supporting the involvement of the p51 thumb in the allosteric action of NSC727447[2].
